What to do if the computer unit is buzzing. What to do if your computer is very noisy? Clean from dust! The power supply is noisy

Often, comfortable work at the computer is interfered with by loud noise from the system unit. And relaxing with your favorite TV series while the coolers howl cannot be called complete.

Noise haunts us at work and accompanies us at home, annoying during gaming battles and unbearable during late-night movie shows. The noise of a working device makes it difficult to enjoy the rustling of a summer night and the singing of nightingales, or to focus on solving a complex problem.

Noise is truly evil, and now we will look at why the computer is noisy during operation and how to reduce the sound of the ill-fated computer.

Why does the computer make noise when working?

Let's find out why the computer makes noise when working. The first thing you need to know about a loud system unit is that the higher the fan rotation speed and the lower the cooler itself, the louder the system unit howls. This is pure physics - a small eight-centimeter cooler operating at a rotation speed of one and a half thousand revolutions is inferior in cooling and noiselessness to a twenty-centimeter big guy lazily rotating at eight hundred. If the fan on your computer is making a lot of noise, the cooler itself may be too small. The smaller the fans are installed in your system unit, the louder the sound from it.

Worn-out, old and broken equipment (not only system coolers, but also hard drives, power supplies) periodically fail and begin to make loud noise. Replacing loose fans and power supplies can reduce sound pollution from your computer.

A cheap computer case - with large cracks, without rubber anti-vibration inserts, and also made of thin sheet metal, the components of which are precariously fastened to each other - a real ode to resonance and loud vibrations. The more ill-conceived the housing design, the worse the sound insulation.

How to reduce computer noise

Standard system units contain the following noise sources:

But sometimes the problem can be solved much easier. It is possible that the computer's BIOS has high values ​​for all coolers. Sometimes it is enough to go to the Hardware Monitor menu and change the FAN settings from Performance Mode to Standard or Quiet Mode.

The computer makes noise when turned on

If your computer makes noise when you turn it on, you probably shouldn’t worry. During the startup and initialization of all systems, the computer spins up all coolers at full power, which then quiet down and begin to operate at specified speeds. But if the system unit shakes abnormally, creaks and howls, the bearings of the coolers of your system unit may have worn out. Until the fans spin up to standard speeds and the centrifugal force takes over, vibration from uneven rotation can be transmitted to the entire system unit. As a rule, replacing outdated components, including the power supply, will avoid this daily torment.

Finally

To be honest, most problems with a loud system unit can be solved by cleaning, replacing or upgrading components. Of course, you can take the computer to another room or to the balcony. Or invest a lot of money and achieve real silence. For example, the author of these words, in pursuit of silence, purchased a heavy, massive case with blank soundproofed walls. I replaced the standard system cooler with water cooling, abandoned the DVD drive and hard drives, and invested in a power supply and a video card with passive cooling that can be connected if necessary. I bought additional SSD drives and replaced the system coolers with special, silent and expensive ones from Noctua.

Was it worth it? The computer could still be heard during in-game battles. But in operating mode the system unit is silent. So much so that I had to additionally turn the backlight brighter so that I could see whether the PC was working and whether it was not wasting electricity. But my sleep became much stronger. True, it was worth a brand new game console with a bunch of games in addition.

Be that as it may, loud noise from a PC is evil, and we hope this article will encourage you to clean or upgrade your computer.

Hi all! If you have visited this page, it means that your computer has started to emit too loud sounds when working, which you can no longer endure. In fact, most people will look for the cause of excessive computer noise before it becomes a problem for their hearing. After all, non-standard sound from the system is a sure sign of a problem and an impending failure.

Causes of noise in a computer

So, in this article we will talk about what to do if The computer is very noisy, and where this noise comes from. It turns out there may be several reasons, and therefore it is impossible to accurately diagnose a possible malfunction just by the fact of a loud sound. However, the most common source of this noise is the computer's power supply. The following devices inside our system unit may also be the cause:

How to solve a problem

If the fan of the power supply, or processor, or video card makes loud noise, then you definitely need them clean(a regular vacuum cleaner with a fine attachment will do). Also, do not forget to lubricate the bearings with special grease. If this does not help, then most likely the cooler is faulty and requires replacement.

When the cause of loud noise lies in the contact of vibrating elements with the body or other devices, then you need to find these elements and return everything back to the way it was. Maybe just some nut has become loose and is rattling.

If possible, try to change the hard drive if it makes a whistling sound. After all, this is not only annoying, but also slows down the computer... which is even more annoying

I hope you found the reason why the computer power supply is making a lot of noise and were able to eliminate it with minimal losses. Good luck!

Noise from the system unit is always a bad sign of computer operation. We should get rid of it not only because it irritates our ears, but it can also affect the performance of the computer, as well as the wear of parts. Today, in this article, you will learn why a computer (in particular, its system unit) is noisy and what needs to be done to remove excess noise, returning the computer to its previous sound level during operation.

7 reasons why the computer system unit is noisy

1. Hard drive problem. The cause of the noise is the way the hard drive works. Moreover, it may not be noise, but crackling, grinding and even tapping. This is especially noticeable when you copy or write something to your hard drive. Such sounds indicate either wear of the mechanism or poor quality material. Therefore, noise can occur both after long and persistent use of a PC, and immediately after purchase. You should not delay this, because if the HDD completely fails, you will lose the files and documents stored on the computer forever and irrevocably. Therefore, you should choose a hard drive carefully, paying attention to reviews from other owners, as well as advice from sales consultants. Of course, our article about that is worth paying attention to.


2. Dusty video card. This device always creates maximum noise, or even better, hum in the room. To be precise, the cooler (fan) that cools the board is most likely to blame. It is often small in diameter, but even one is enough to create a loud and unpleasant noise. It is usually located “upside down” and its blades can touch the edge of the video card box. It is quite difficult to avoid such noise; it is easier to install it in your system unit. You can solve the issue without buying a new device, but to do this you will need to disconnect the video card from the motherboard, and then disassemble it to get to the cooler and lubricate it, which is very problematic! Also remember that this component is very fragile and can be easily broken. If you still manage to get to the axle, then it needs to be checked for integrity, and then lubricated with silicone oil, which will remain inside the cooler for a long time and thereby prevent noise from occurring. If the axis has already shifted and torsion creates friction against the edges of the box, then the box can be slightly trimmed or sawed off. It won’t look very aesthetically pleasing, “but it will be cheap, reliable and practical” (c)!


3. The processor cooler is clogged. Another reason that creates a lot of inconvenience for the computer user. As you know, any motherboard has a processor installed, which is also called a “stone,” and a radiator with a cooler is additionally installed on this stone. The created design is quite bulky and collects dust well, since the cooler blows air (from the system unit) to cool the radiator, which in turn transfers the temperature to the processor. As a result, a large layer of dust accumulates between the cooler and the radiator, which gradually grows, thereby complicating the movement of the fan. The dust layer adds extra noise, and it also gets into the axis, which causes the speed to be lost and a hum begins to be heard. It's very easy to get rid of everything! First, disconnect the fan, clean it and the radiator from dust. Now disassemble the radiator itself and lubricate the axle with the same silicone oil. Now put everything back together, tightening it thoroughly with screws so as not to create unnecessary vibration.







4. Old power supply. The power supply is a device that is recommended to be changed every 2-3 years, since it is responsible for the safety of the entire PC. In addition, this time frame is just enough to dust all the internal parts of the power supply. After all, there is the same cooler that blows in air from outside to cool the parts as on the processor. The air carries particles of debris and dust. As a result, noise occurs in the same way as in the case of a video card or processor cooler. However, there can be much more noise here, since the rotation speed of the power supply cooler is higher, since its diameter is larger, and to be honest, not all manufacturers think about creating a quiet fan in the power supply. Of course, you can get rid of the noise yourself by disassembling the unit, cleaning it and lubricating it. But again, not all models have the ability to easily access content. The site’s specialists strongly advise purchasing a new power supply rather than disassembling the old one, because the new one will produce less noise and will give you additional confidence in the serviceability of this personal computer device.


5. Incorrectly selected optical drive. Rarely, but it still happens that noise is created not by the entire system unit, but only by the optical drive, which is more familiar to users under the name “CD-DVD ROM”. The reason for the noise is the rather low quality of the device. However, be careful here, noise can only occur when a disc is inserted into the optical drive. If there is nothing there, then there will be no noise coming from it. If you notice noise precisely when this device is operating, then we have to disappoint you, because... it is practically beyond repair. Even in warranty service centers they are not repaired, but replaced with new ones. We would generally advise you to abandon their use in favor of flash drives, since today with the help of the latter you can carry out all the same operations, even .


6. The motherboard or other device is cracked. Noise from the system unit can come not only due to flaws in the operation of the cooler or due to manufacturing defects, but also for completely physical reasons: a cracked motherboard, large debris in the system unit, a cracked video card box, etc. This will cause various kinds of rattling and whistling noises due to the effect of air pumped by coolers on the part. To do this, you need to disassemble the system unit and check its “internals” for defects. This could only happen due to a fall or an accidental/intentional blow. For example, many PC users, when they slow down, hit the system unit with their foot or hand out of anger. Such actions may cause chips, cracks, dents and similar defects.


7. Poor fastening of parts. If you are asking the question “Why is the computer system unit noisy?”, then you need to check all the fasteners in the system unit. To do this, first open the unit cover. Now take a screwdriver (phillips) and try to tighten all the screws and screws that you can see. Start with the motherboard, since it contains a large number of components, so if each of them is poorly secured, then when they work, the “motherboard” will begin to move in waves, each time touching the metal case of the system unit. Next, check the fastening of the processor (especially the cooler) and video card. Then examine the hard drive mounting. If it does not have anti-noise fixation using slotted gaskets or plastic holders, then rest assured that the noise arises precisely because of poor fastening of the hard drive. Therefore, try to lay a small layer of rubber between the metal beams, which would soften the vibration without spreading it throughout the entire system unit. You also need to attach an optical drive. The last thing you need to check is the power supply. Tighten its mounting bolts as well. If there are additional coolers in the system unit case, check them too.

What to do to get rid of noise from the system unit?

If you don’t see any problems with the components, but simply want not to hear the computer operating, then you can do just a few steps that will help almost completely absorb the noise.

1. Change the cooling system. Only a radical change in cooling, namely replacing it with liquid cooling, will help get rid of noise once and for all. Thus, it is not fans that will cool the computer components, but liquids, using pumps, heat sinks, radiators, hoses, sensors and similar devices. The difference will be quite noticeable, but such a system costs about 500 (and sometimes more) US dollars. Too expensive!


2. Change the system unit box. Sometimes it is enough to change the system unit box to reduce the noise level. For example, you can choose a box with noise and vibration insulation (or even make one yourself). Also think about the legs on which the system unit stands; they should be soft and absorb vibration well, i.e. rubberized.


3. Change coolers. The most optimal option for reducing noise (low-cost and noticeable by ear) is to replace all old coolers with new, more modern and silent ones. However, here it will not be possible to waste time on trifles, otherwise you will not feel the effect as such! Some can even be customized by choosing either a quiet rotation mode or a loud, but more powerful one (it is needed for those cases when the PC will be used for a long time without interruptions).


4. Carry out regular. If you regularly read our magazine, then in almost every article we mention cleaning your computer, since it is really very important and useful for the system unit, so do not miss this point from our recommendations. After all, regular reading will save you from unnecessary problems associated with noise coming from the system unit.

Now you know about all the causes of noise from the system unit, as well as how to get rid of it.

Has your computer become significantly louder than usual? Does it buzz or hum loudly, especially when turned on?

In 99% of cases, one or more cooling fans fail, and if you do not solve this problem, then you will face not only a migraine from constant noise, but also the very likely death of your computer from overheating.

REMEMBER!

Any actions inside a computer system unit or its parts can be carried out ONLY with experience working with electrical appliances and electronics, clearly understanding the mechanism of operation of the device and the essence of the operations performed. All actions inside any devices and mechanisms are carried out EXCLUSIVELY when the power is turned off. Including - the cord must be pulled out of the outlet and the body must be grounded.

In general, don't be idiots - follow the electrical safety rules and be reasonable. I warned you.

So, the first thing you should do is find out which cooler (fan) started acting up. To do this, remove the side cover, simply turn on the computer and listen - you can localize the source of the noise with sufficient accuracy.

There aren't that many of them.

Case fan

Most often, case coolers located on the rear end or side covers of the system unit fail. Replacing them is not difficult.

Firstly After turning off the computer, carefully unplug the power cable. It can either connect to the power supply using a standard molex connector, or to the motherboard using a small 3 or 4 pin connector. If you have little knowledge of computers, remember where the fan was connected. After this, use a Phillips screwdriver to unscrew the four screws that secure the cooler to the case. Take it out (cooler).

Although if you really need to replace it, but don’t have the money to buy a new power supply or call a technician, you can try. I will tell you about the method of replacing the cooler on the power supply a little later, in a separate note.

Are you familiar with the situation when you hear extraneous noise from the system unit? This is not only unpleasant, but it is also always a warning that some part of the system unit may soon fail. You need to get rid of this phenomenon as soon as possible so that the coming sound does not irritate your ears, and the computer’s performance does not decrease due to increased wear of parts. Offering to understand in detail the problem, why the computer is noisy and what needs to be done to get rid of excess noise during its operation and return the computer to its original operating mode.

The main causes of computer noise

Computer noise is not as noticeable during the day as it is at night. Imagine that you need to work or just relax by watching a movie or browsing the Internet. Agree to do this accompanied by strange sounds emanating from the system unit, which is not entirely pleasant, and sometimes even irritating. Therefore, I will now talk about the main malfunctions that lead to the appearance of strange sounds from the computer system unit in the sequence of their possible appearances.

Hard drive problems

The cause of extraneous noise may be the operating characteristics of the hard drive. This often becomes noticeable when some information is copied and recorded. In this case, not only noise can occur, but also tapping and grinding. The occurrence of such sounds may indicate poor-quality material or wear of the mechanism, so noise may appear either immediately after purchasing a PC, or after its long and persistent use.

I would like to note that the hard drive can make some sounds in the form of crackling sounds from the first time it starts working. This applies to inexpensive or older models. High-quality expensive models operate quietly or almost silently.

There is no point in delaying the solution to such a problem (especially if the hard drive was working quietly before), because if the HDD drive stops working, you will irretrievably lose all documents and files stored on the computer. In order to avoid such an unpleasant situation, you need to carefully consider the choice of hard drive, pay attention to the advice of sellers and reviews of owners.

If you already own a noisy hard drive and there is no way to buy a new one, I suggest two ways to solve this problem:

1. Reliable fastening (fixation) of the disk in the system unit case using special soft gaskets. This will get rid of resonance and vibrations.
2. Reduced read head positioning speed (Automatic Acoustic Management or AAM for short), which creates a characteristic crackling sound. This can be done using the quietHDD program in the AAM Settings section. The program must be added to startup.

Video card

It is this device that always creates the maximum amount of noise (hum) in the room where the computer is installed. The reason is not the video card itself, but the cooler (fan), which serves to cool the board. Basically, it is quite small in size, but this is quite enough that it can become a source of loud and unpleasant noise. Modern powerful video cards are equipped not with one fan, but with two or even three, which can increase the noise many times over.

Most often, fans are made on bushings, and when dust gets into it, the bushing breaks. Because of this, the fan blades can reach the edges of the video card case. Getting rid of such a source of noise is not easy. The simplest solution would be to replace the cooler.

There is another way to solve this problem. To do this, you initially need to disconnect the video card from the motherboard, disassemble it in order to get to the cooler and lubricate it, which is very problematic. Please remember that this device is quite fragile and can be easily damaged. If you still manage to get to the axle, then you must first check it for integrity and then lubricate it with silicone oil. It perfectly prevents noise during operation.

If the axis has nevertheless shifted and during operation the fan blades rub against the edges of the housing, then the housing itself can be cut down or cut off. True, it should be noted that this will not look entirely aesthetically pleasing, but it will allow you to get rid of annoying noise without extra costs.

CPU fan

This reason is very common and creates a huge amount of inconvenience for users. The motherboard contains a processor, which is also often called the “stone”. So, a radiator with a cooler is additionally installed on it. This design is very bulky in appearance and at the same time collects dust well, which accumulates between them. A large layer of dust gradually increases and complicates the movement of the fan and creates noise. In addition, dust enters the axle, which causes a decrease in speed and a hum appears.

Solving this problem is quite simple. First of all, you need to disassemble the processor cooling system and clean the fan and radiator from dust. Then you need to disassemble the radiator itself and lubricate the axle with the same silicone oil. During assembly, make sure that the screws are well tightened to avoid vibration.

power unit

Experts recommend replacing this device every 2-3 years, since it is responsible for the safety of the entire computer. During this time period, all internal parts of the block become dusty, since the block also contains a cooler, which serves to cool the parts. With the blown air, dust and debris particles get inside the device, which, as in the case of a video card and cooler, cause noise. However, in this case, the noise level is much higher, since the rotation speed and diameter of the fan are much larger, and not all computer equipment manufacturers care about creating a silent fan in the power supply.

You can get rid of the noise yourself by disassembling, cleaning and lubricating the fan. However, it should be taken into account that not all block models allow easy access to the content. You can also remove the protective grille near the fan, which will help reduce noise or eliminate it altogether.

In order to get rid of noise and be sure that the power supply is working properly, the best solution would be to purchase a new device to replace the old one.

Optical drive

In one of the least common situations that still occurs in practice, the cause of noise may not be the entire system unit of the computer, but only the optical drive, which is better known to users as “CD DVD ROM”. The reason for the noise in this case is the poor quality of the device. In this case, you need to be quite careful, since noise can only occur when the disk is in the device. If there is nothing in it, then there will be no noise.

If this particular device is the cause of the hum, we have to disappoint you, since it is practically beyond repair. It should be noted that they are not repaired even in warranty service centers, and in case of breakdown they are simply replaced with new ones. The best solution would be to completely abandon the use of such devices in favor of flash drives, which today are already very common and are used everywhere. In addition, with their help you can carry out all the necessary operations, including even installing Windows.

Any device or motherboard is cracked

Noise can arise for various reasons and this can occur not only due to manufacturing defects, clogging or defects in the operation of the cooler, but also for completely physical reasons. For example, the cause may be a crack on the motherboard, a crack in the video card case, or the presence of various debris in the system unit, etc. Due to the effect on the part of the air pumped by the coolers, whistling, rattling or other extraneous sounds may occur, which are usually not observed during normal operation of the system unit.

In order to determine the cause, you need to disassemble the system unit and check the contents for any defects that could arise as a result of an intentional or unintentional impact. For example, some PC users may hit the system unit out of anger while the computer freezes. As a result of such actions, all kinds of defects arise, including dents, chips, cracks, etc.

Fastening parts

If the computer is noisy or makes an unusual noise, you need to check all the fasteners inside it.

In order to carry out this check, you first need to open the unit cover. After this, tighten all the screws and screws that you can reach with a screwdriver (Phillips). You need to start with the motherboard, to which a large number of components are attached. If any of the blocks is poorly secured, during operation the motherboard begins to vibrate and at the same time touch the metal case of the system unit.

Then you should check the fastening of the video card and processor (especially the cooler). Next, you should pay attention to the mounting of the hard drive. If it does not have an anti-noise fixation that uses slotted gaskets or plastic holders, you can be sure that extraneous noise arises for this very reason due to poor fastening of the hard drive. In order to make the noise level significantly lower, you can lay a small layer of rubber between the metal fasteners. It will soften the vibration that occurs during operation, preventing it from spreading throughout the system unit. The optical drive needs to be secured in the same way. After this work is completed, check the power supply. Don't forget to tighten the mounting bolts and screws. If there are additional coolers in the system unit, then you need to check them too.

A very important point will be the correct installation of connecting wires and cables. All of them must be connected to each other with plastic ties (clamps) and laid so as not to touch the fans.

What needs to be done to get rid of noise from the system unit?

If the problem of extraneous noise does not lie in the components, but you do not want to hear the computer operating at all, you can take several actions that will allow you to almost completely get rid of the noise of the system unit.

Changing the cooling system

If you want to eliminate noise once and for all, you should radically change the cooling system, namely, replace it with a liquid one. When using this system, computer components are cooled not by fans, but by liquid using specialized pumps, heat sinks, sensors and other devices.

A liquid cooling system can almost completely eliminate noise, but the cost of such a system is quite high and amounts to about 500 (and in some cases more) US dollars. This is quite an expensive pleasure that not every PC user can afford.

Replacing the system case

In order to significantly reduce the noise level, sometimes it is enough to replace the system unit case. You can purchase a case with vibration and noise insulation, or make it yourself. Also think about whether the legs on which the system unit is located are capable of absorbing vibration well, for example, being rubberized.

Replacing fans

One of the most acceptable ways is to replace coolers with modern, quieter ones. It should be noted that when carrying out this action, you should not waste time on trifles, otherwise there will be no noticeable effect.

You may need to install a more powerful fan that will not work at its maximum capacity, thereby creating noise or hum.

Regular PC cleaning

Regular cleaning of your computer is very important and beneficial for the system unit, so this operation should be carried out periodically (once every six months). This will save you from various problems, including the occurrence of various noises in the computer system unit.

I hope I explained to you in detail why the computer is noisy and what needs to be done to get rid of extraneous sounds. Take care of your computer and it will work properly for many years!

The computer is noisy. What to do?

Hello. I remembered today that computers have such a bad property as making various unpleasant, alarming, and sometimes irritating sounds. Therefore, today I will try to tell you where and why these sounds can appear and how to eliminate them.

If a computer is noisy, not a laptop, but a personal one, it is most likely the system unit that is making noise. But I used to have a monitor that had a built-in fan, and it really made noise, no, it didn’t even make noise, it hummed :). And I was still afraid to turn it off, lest the monitor burn out, such a sad story, but let's get back to the noise that comes directly from the system unit. First, let's figure out what can make noise, whistle, or hum in the system unit.

1. Fans (coolers). There are quite a few of them in a modern computer. At least one on the processor, a second on the power supply, and most likely one more on the video card. Of course, they all spin and make a little noise, this is quite normal. But today we are talking about strange and unnatural sounds. These fans can make such sounds when they are all covered in dust, or when they break and the lubricant can still be worn off.

2. The case itself and the components in it. I saw one computer that beeped a lot, after it crashed it stopped. This indicates that something has come loose somewhere, has become unscrewed, and when the computer is running, of course, it vibrates a little, so it whistles.

3. Hard drive. To determine where the strange noise is coming from, you need to turn off the fans, and if it turns out that this unpleasant noise is coming from the hard drive, then this is bad, as most likely it will completely fail soon. Save the information before it’s too late, of course I can’t say for sure, but it’s better to be safe.

4. CD/DVD drive, although it only makes noise when there is a disc in it, so you don’t have to pay attention to it.

Is your computer noisy? Let's solve the problem.

Let's now look at an option on how to solve problems with computer noise.

1. If the fans are noisy, then everything is very simple, either you can simply clean the fans from dust, or lubricate them with a special lubricant, or simply replace them. Usually, if the computer is not very old, then simply cleaning it from dust will save you from noise. Just be careful and clean carefully.

2. If you have fixed problems with the fans or simply turned them off, but the noise remains, then most likely the problem is in the case or components. No, they don’t break, something must have come loose. Just take a screwdriver and check all the bolts and tighten them well.

3. I think everything is clear with the hard drive. It usually makes a nasty whistling sound, usually this happens in old hard drives that have already served their purpose. And I advise you to replace it.

Of all these tips, you will most likely only need to clean your computer; I know from my computer that after cleaning the fans it runs much quieter and, of course, cools much better, which is very good. Good luck!

What to do if your computer is very noisy?

Now we will tell you what to do if your computer is noisy (or “buzzing” - depending on who you like). First, let's figure out what is the source of noise in the system unit of your computer. The greatest noise comes from fans (coolers) that are designed to cool those computer components that are subject to the greatest cooling during operation.

During operation, the power supply, central processor and video card become very hot. If you do not have water cooling installed, then all these components are usually cooled using coolers (some video cards can come with passive cooling, that is, without a fan). Also, many system units have additional fans installed that “drive” air inside the case.

If your computer starts to make a lot of noise, the first step is to clean it from dust. We have already described how this is done in this article. If after removing the dust the situation has not changed, then you should determine which fan began to make increased noise.

You will have to check each fan individually when you turn on the computer. To begin with, you can take a regular pen refill (not metal, of course) and insert it into the power supply fan (of course, not the side with the metal tip), then turn on the computer and after 1-2 seconds remove the refill. If, after you remove the rod, the sound increases sharply compared to normal, then you need to replace the power supply fan. You can check the other fans in the same way.

Attention! Don’t even think about stopping a running fan - there is a high probability that it will “live for a long time.” I checked :)

The fact is that the operation of the fans can be controlled by a special circuit that changes the fan rotation speed depending on the temperature; it is this circuit that can fail. If the fan starts to make a lot of noise only when you turn on games or other resource-intensive applications, then it is most likely that the cooling system of your CPU is not effective. Let’s say I was unlucky with the processor, I got a Pentium 4 (don’t be surprised that in 2011 I have such an old “stone”; I don’t play games, but I have enough resources for the rest) of the 531 series with high heat dissipation. The processor cooling fan began to howl under any slight load, for example, when archiving files.

Since I often sit at the computer at night, when there is silence around me, the extra noise began to “get me” pretty much. For this reason, I decided to purchase a powerful cooling device. After wandering around the store and listening to the recommendations of the sales assistant, I chose the Cooler master gemin II.

Cooler master gemin II

As you can see, the system is quite serious - with a copper base and six copper heat pipes. The design provides for the installation of two 120 mm fans. To be honest, when I bought this miracle of technology, I had some doubts whether the power supply would interfere with the installation of the cooling system. My doubts were not without reason, since I had to unscrew and lift the power supply to install the device. This is what Cooler master gemin II looks like in my system unit.

Cooler master gemin II in the system unit

What is good about this cooling system is that it installs exactly 120 mm fans, because... they operate almost silently. Moreover, since the cooling fins of the system are located perpendicular to the motherboard, both the board chips and the RAM are cooled. And in general, air circulates well throughout the entire case, which makes it possible not to use additional “purge” fans.

In principle, for the Cooler master gemin II cooling device to operate efficiently, one fan is sufficient. For the sake of experimentation, I tried to “drive” the computer by turning off both fans of the processor cooling device, but alas, temperature control showed that without fans the device does not provide normal cooling. The processor temperature increased to 70 degrees, which was even worse than with a boxed cooler.

Conclusion: it’s not worth using even such powerful cooling systems for processors as Cooler master gemin II without a fan.

After I installed Cooler master gemin II into my system unit, the main source of noise was the power supply fan. My power supply had an 80 mm fan installed, which is much louder than the 120 mm fans that are installed in almost all modern power supplies.

For fun, I conducted the following experiment: I opened the cover of the power supply, turned off the “native” 80 mm fan, and instead of it, attached one of the fans from below that was previously installed on the Cooler master gemin II. The effect exceeded all expectations: the computer began to work almost silently under any load, but... the sounds that the Seagate Barracuda hard drives made during operation (I have two of them) began to be heard.

In general, Seagate Barracuda hard drives are very reliable, but some models (specifically, the ones I have) are absolutely noisy if nothing drowns them out. In short, the periodic grinding of hard drives at night irritated me even more than the monotonous noise of the power supply fan. For this reason, I found a compromise: I replaced the original fan of the power supply with an 80 mm, quieter Glacial Tech fan (of course, you can install other “branded” fans, for example ZALMAN).

As a result of the actions taken, I received a fairly quiet computer, which is what I actually wish for you.

The computer system unit is noisy

Regardless of the computer model and the hardware it has, sooner or later certain problems may arise. The system unit is noisy - this is one of the common problems that PC owners encounter. This malfunction not only irritates the user's hearing, but can also negatively affect the performance of the computer and also lead to failure of the machine. Let's figure out why this happens and what to do if the system unit is noisy.

Causes of noise and ways to eliminate them

In order to return the PC to its previous sound level during operation, it is first necessary to determine the location and cause of the malfunction. Typically, the occurrence of this problem is associated with a malfunction of ventilation elements, cooling systems or hard drives. Sometimes the computer makes a loud noise from system overload, which causes the temperature inside the processor case to rise above normal. Please pay attention to the following frequently occurring factors that cause an increase in noise levels during operation of the system unit.

Dust accumulation on the CPU cooler

Perhaps the very first thing to do is check the fan that is responsible for cooling the processor.

This is where the most dust accumulates, which over time disrupts the normal cooling process and leads to overheating of the computer's heart. For this reason, the fan begins to spin faster and hum louder, the hardware heats up, and the operating system freezes and is not stable. In some cases, dust clogging the fan causes the computer to stop starting. In addition to accumulated dust, over time the thermal paste located between the heatsink and the microprocessor retainer, which serves to improve the transfer of thermal energy, loses its properties, which also negatively affects the cooling of the system.

Advice! If the computer is under warranty, then under no circumstances open the system unit, even if you are sure that you can fix the problem yourself. Use the services of the service center. To independently correct the operation of the main fan, you must do the following: 1. completely turn off the computer's power; 2. open the side panel of the system unit; 3. disconnect the fan from the motherboard; 4. disconnect the cooler along with the radiator; 5. clean using cotton swabs and a vacuum cleaner or hair dryer; 6. if the thermal paste has lost its quality and looks like dried gray chewing gum, it needs to be replaced; 7. After cleaning, reassemble in reverse order.

If you have a relatively new computer, then you can clean the cooler without removing it, using cotton swabs or a brush and a vacuum cleaner.

Attention! Do not use a damp cloth to remove dust from the fan or motherboard, as this may cause a short circuit. Thermal paste can be found in almost any computer store. It is sold in small tubes or syringes of several grams. Usually one tube is enough for 2-3 applications.

If necessary, you can disassemble, clean and lubricate the fan itself. But if you're not sure you can handle it, just peel off the top sticker, remove the plastic cover and drop a couple of drops of silicone grease onto the motor shaft. If the cooler is old, this procedure will help make it less noisy.

Power supply cooler is dirty

Another common problem that causes loud noise and overheating of the computer is the accumulation of dust in the power supply fan.

To eliminate it, you must: 1. turn off the power and disconnect the network cable from the processor; 2. remove the side panel of the system unit; 3. remove the power source without disconnecting the wires; 4. remove the top cover of the unit; 5. clean the inside using a vacuum cleaner and a brush; 6. remove the fan and lubricate it (as in the previous case);

7. assemble everything in reverse order.

Advice! Do not use an old Soviet vacuum cleaner, which produces electrostatic interference, for cleaning, this may damage the board. This procedure will help increase the air flow blown by the fan, as well as reduce the noise of the system unit.

Hard drive failure

Sometimes when your hard drive is running, especially if you are copying something to it, you may hear loud noises, grinding noises, and knocking noises. Such sounds indicate either poor quality of the hard drive or wear of the mechanism. In such a situation, the hard drive can fail at any time, which threatens the loss of all information stored on it. Therefore, if such a problem occurs, do not delay and contact a service center if the computer is under warranty, or replace the hard drive with a new one.

Video card malfunction

Dust accumulation in the graphics card cooler can also cause loud and unpleasant noise.

The fact is that the video card is in an upside-down state and the accumulation of dust over time leads to a displacement of the cooler axis. In this case, the blades begin to touch the video card case, producing a strong hum. Removing dust and lubricating the cooler axis does not always help in this situation. Alternatively, you can try to trim or saw off the edges of the metal case where contact occurs.

Advice! The video card components are very fragile and easy to break, so be extremely careful when disassembling.

Other solutions to the problem

Loud noise from the system unit can come not only from the above problems. Sometimes old or low-quality hardware can be the reason why your computer is humming. In such a situation, in order to absorb unpleasant sounds, it is necessary to upgrade the machine.

Replacing the cooling system

The noise can be significantly reduced by replacing the air cooling system with a liquid one. This option is almost silent and is capable of perfectly cooling the PC filling. The only disadvantage of a liquid cooling system is its high price.

Installing new coolers

Today you can find modern, almost silent coolers that also do their job well. Alternatively, you can replace all the old fans with them.

Changing the system unit box

On sale you can find boxes that have vibration and noise insulating properties, which are easily capable of completely absorbing sound waves and vibrations. Finally, a few more tips that will help reduce the noise level of your computer: regularly clean the system unit from dust, thanks to this you will also significantly increase the service life of your PC; make sure that the system unit has rubberized feet that absorb vibration well;

Do not leave the computer constantly on; if possible, put it into sleep mode or turn it off, this way it will overheat less.

The computer is very noisy. What to do?

Computer noise bothers many users. Some modern computers are designed with acoustics in mind, but many still use cheap cooling components that create noise. Rotating parts, motors and case cooling fans make the most noise. The fans make the loudest noise. Also, hard drives and fans vibrate, and the chassis design and surface only increase vibration noise. Modern video cards and processors require cooling, which means the fans will make even more noise. High-speed disk drives spin disks at high speeds and make loud noise. Winchesters don't work silently either. But you can reduce the noise while maintaining cooling. There are several components available for assembling low-noise computers.

Sound-absorbing housing

When building your own computer, consider purchasing a case with quiet fans and wider vents.

Fans

There are at least two fans installed in the system unit case. One is on the processor heatsink, the other is in the power supply. Today's processors require constant heat dissipation, which can only be provided by a very powerful and noisy fan. How to reduce fan noise? The easiest way to do this is to lower the fan supply voltage. Most fans operate at a standard voltage of 12 volts. It can be lowered to 5 or 7 volts. It will be equally effective to directly suppress the noise of moving mechanical parts of the cooler. The loudest fan is the one on the CPU heatsink, and there are three reasons for this:

1) It forces a large amount of air through the needle-shaped surface of the radiator.

2) It has a worn out or poor quality mechanism.

3) It is clogged with dust.

The last two problems are easy to fix. Dust is removed using an alcohol-soaked cotton wool wound around a match. Mechanical parts will need to be lubricated with machine oil.

Fans with temperature sensors.

These fans are equipped with temperature sensors, and when the temperature drops, the rotation speed of the blades slows down.

The power supply fan is larger than the processor fan, but it is less noisy. Voltage reduction and lubrication techniques apply to it as well.

Hard disks

A hard drive in a protective shell is quieter. You can muffle the noise from the hard drive by placing foam strips where it touches the case. Then the hard drive will not be in contact with the computer case, and the foam will absorb all vibration. However, you should not completely wrap the hard drive in foam rubber, because it requires air.

High speed CD-ROM drives

Modern CD-ROM drives create noise that easily drowns out all other computer noise. What to do? Creative Labs has developed iNFRA drives, which have a button on the front panel that reduces the rotation speed of the disk by half. This keeps noise to a minimum. Owners of other drives can achieve a similar effect by setting their drive to maximum operating speed.

Move your PC to a different location

An elementary solution - if your computer is on the table, right under your nose, just move it to the floor (of course, if the case is not designed for vertical installation). The computer vibrates, which often causes the desk to vibrate in response, turning into a resonator. This problem can also be solved by simply relocating the computer. The best option would be to place the computer on the carpet. If the floor of your room is paved with parquet or tiles, then you can place a piece of foam rubber or carpet under the system unit. You can even buy extension cords for the monitor, keyboard and mouse, and take the system unit even to the next room. You just have to get up every time to install the disk.

Down with vibration!

In some cases, the loudest noise comes not from the motors and fans, but from the vibration of the computer components. To solve this problem, sometimes you just need to remove the case and tighten the fastening screws of all elements. But this must be done carefully so as not to break anything. Special anti-noise screws with rubber or plastic washers are sold.

Almost all computer sounds can be muffled using sound-absorbing foam that is installed inside the case. It is installed very simply - a gasket is cut out that corresponds to the dimensions of the inner surface of the housing walls. Hard drives are encased in special soundproofing shells. But remember that in addition to sound insulation, these gaskets also impair heat dissipation, and you need to use them carefully.
