During PC operation, its components are heated. HDD, rAM and disk drive Mix a minor amount of heat, which is dissipated by naturally. And here cPUThe video card and the power supply is warm much stronger, so they are installed cooling radiators with fans (coolers).

It is their sound that is heard when working. In normal condition, the coolers should not interfere with the user. But if one day the hum became so strong that it is impossible to focus, it means it's time to find out and eliminate the cause of the unpleasant sound.

We decided to independently eliminate the problem, it means that we boldly open the side cover and proceed to the search for the culprit. Most fast way Find noisy fan - it is a little slow down each of them on a working PC.

Arming with a soft tassel and light touches to the impeller slow down the processor propellers, video cards, power supply and housing (if available). When a particularly noisy "Carlson" is found, turn off the computer and try to eliminate the unpleasant sound.

Small dust particles inevitably accumulate inside the system unit, forming a whole layer. Therefore, it is very important to monitor the internal state of the PC and on time to clean. With the help of the same tassel and the vacuum cleaner, carefully clean the blades, and at the same time other places where dust is present.

Special attention is paid to cooling radiators, as the entire mud bundles are sometimes accumulated. After the completion of the procedure, we turn on the PC again and listen. If the fan is very much noise on the computer, go to the next step.

The noise level depends on the speed of rotation. And the rate is adjustable depending on the temperature of the internal environment. Therefore, if one day the system started to buzz, we recommend checking the temperature sensors using any free program.

For example, when overheating is central or graphic processor It will be necessary to remove the cooler and replace the dry thermal chaser. Most likely, after that, the efficiency of the radiator will increase, and the speed of rotation and the noise will come back to normal. If the problem is not gone, "digging" further.

Low quality details

It happens that the computer is loudly noisy immediately after purchase or shortly after it. In such a situation, the reason can be wounded in a cheap cooler. There are uneven edges in such details of the propeller blade, and the sole of the radiator is too rough. If you caught such an instance, then either come across loud soundOr replace a more advanced model without such defects. For example, on tested brands - Zalman, Thermaltake, Cooler Master.

Worn iron

The fans bearings are designed for the entire service life, but this moment occurs when the lubricant sweeps into them, and metal parts are stepping. The noise of such a cooler will increase gradually, increasing every time. At the initial stage, you can try to extend the resource by adding lubricants to the bearing. For this:

• Remove the sticker from the central part of the propeller.
• Drip several droplets of the machine oil into the hole.
• Tighten the blades slightly so that the oil is separated.
• Run the computer.

If the wear is small, then the noise should decrease. Otherwise, you will have to replace the item.

Another cause of a strong humus can be a cabinet fan of a small diameter. Often, when choosing cam propellers, they do not think about the size and buy the valves of small diameter. But that there is at least some sense from them, the speed of rotation must be quite high, which means that the sound will be appropriate.

Therefore, when choosing an additional "Carlson", take the most large diameters of the blades, so that it is not to suffer with a terribly buzzing cooler.

Power supply cooler

Cooling video card

Cooler processor

Noisy fans in PCs are a big problem if you prefer to listen to music at a computer, read books or do business requiring concentration. Annoying distracting buzz, especially on increased speeds, does not help, but only distracts from what you do. But there are a number of ways to avoid or at least reduce this attack.

How to protect yourself from noise

The reasons for - a lot. They are conventionally divided into those that can be eliminated independently and those that require a professional intervention from the service center. Since it is obvious that the help of a specialist is an extreme case for those who know how to use elementary tools and modern software, it is worth considering what is available to each user.

The fan may be noise due to high revolutions or small diameter, and sometimes on both reasons. Help in solving this problem can replace a small fan for a larger in diameter. The large size of the blades gives the best air flow that does not require high speed and is usually less noisy.

It also happens that the fan begins to make noise due to drying the oil in the rotating part. You will need a screwdriver and a little special lubricant to return everything in a normal state. Specialized computer stores sell the necessary oils for fans. If you are experiencing difficulty choosing, contact your seller consultant, it will prompt the best option.

In addition to the reduction of noise from the fan rotation, you can resort to other methods of noise protection. For example, there are system blocks laid out from the inside soundproofing materials. This gives a good result if the fans themselves are impossible. You can make such protection yourself with the help of foam rubber or special materials.

As a radical way to combat noise, it is possible to offer the replacement of conventional water cooling fans. In this case, all parts are changed to a special system of tubes, pumps and radiators. The advantages of such a system are that there is no noise except water bouffaging. Cooling efficiency is even higher than in many other systems. There is a lack of bulky equipment and water leak opportunities.

Special PO

It is possible to reduce the noise using special programs. The simplest thing is to take advantage bIOS settingswhere there is a Speedfan option. In some systems, this value can be adjusted, exposing optimally suitable in your case. So that no overheating occurred and there was no excess noise.

In addition, there is separate program with the name of the same name. It is convenient what works from Windows and does not require knowledge of BIOS. It makes it the same, only much easier.

The noise coming from the system unit can signal a variety of problems. But even if it is known that it comes from one of the fans, it should not relax, because high-quality uninterrupted cooling is the key to the long service of the computer.

Most people trying to keep up with progress, constantly update their PCs and seek to replace them with new, more advanced. Nevertheless, the option is not excluded that the fan is noise due to the fact that it is an old model, apparent loud on the background of modern, almost silent. If the sound appeared recently or unexpectedly, there are several fault options that can cause it.

Power supply cooler

The cooling system of the power supply unit can make noise. If the room is dust or the entire system without replacing elements has been running for several years, pollution is even there, bypassing all the protective boundaries. Noise usually most of all from this detail, since the cooler has a large diameter and a very high speed of rotation. To clean and purging the power supply will have to be disassembled.

Some models disassemble enough easily, the main thing is to remember where what bolt is unscrewed. Then, clearing and smearing the necessary parts, assemble the block and install in place. Options that do not assume simple disassembly will have to be changed. In any case, experts advise to put a new power supply every two or three years, regardless of the presence of noise and failures.

Cooling video card

The problems often arise due to the fact that to achieve maximum efficiency it is in most cases installed in an inverted form. With large long-term loads, it can gradually shift, starting to touch the static surfaces with blades. If this happens, even the fan is such a small diameter can noise very much.

The easiest way to solve the problem of purchase new video card. But if desired old noisy option can be separated from motherboard, Check the fan axis and lubricate it. If the axis has shifted, you will have to write a little edges of the video card box so that the blades stop touching them.

Cooler processor

The cooler of the processor is also quite often noise. It hits the most dust, and it is the least protected. The main layer accumulates between the fan and the radiator, where the air is rushed for the subsequent cooling. To clean the system, the fan is disconnected and clean both items separately, if necessary, lubricate.

Extremely undesirable to use a vacuum cleaner when cleaning coolers. This is convenient, but sliding particles of dust create static electricity, which can lead to a breakdown of the system.

Noise or hum from a computer is what annoys all users. But, some computers are noisy so strongly reminded by a transformer booth. If this is your case, then this article should help you. Here you will know why the computer is buzzing or noise and what to decrease this noise.

Why buzzing or noise computer

Usually, only two noise sources are in the computer, it is noise from fans (coolers) and noise from hard disks. Noise from hard drives is so insignificant that it can be seen only if the fans work very quietly either do not work at all. Therefore, hard drives can not be taken into account at all and focus on reducing noise from the fans.

The coolers in the computer are cooled only three components, it is:

• Power Supply.

Plus, usually in a computer case there is at least one so-called body cooler. The problem of body coolers output the heated air from the computer case, as well as drive inside the fresh and cooler air.

As for the noise level, which produces each of the fans, it depends on the following parameters:

• Fan rotation speed. The faster the fan rotates, the more noise from it.
• Fan size. The smaller the fan, the more he is noise and, the less benefit from it.
• Quality of fan performance. The fans are very different at the price and as a result of quality. Cheap fans are usually produced using cheap bearings and low-quality plastics. Therefore, cheap fans are no longer no longer.

Also on the noise level that hears the use of the computer, the housing itself affects. Cheap enclosures are made of thin metal, which rattles and thus enhances the noise from the fans. In addition, there is no interlayer of the soundproofing material in cheap corps.

What to do if the computer is very buzzing or noise

So, we dealt with the causes of the noise and the roast from the computer. Now you can disassemble the main ways to reduce noise.

Method No. 1. Reducing the fan speed.

The easiest I. effective method Reduce the noise level from the computer is to reduce the turnover of fans. The speed of the fans that connect to 4 to the contact connector can be adjusted via BIOS or through special software, for example, for this often use the Speedfan program.

Speedfan program

If the cooler is connected through 3 pin connector, then its rotation speed can be reduced using special adapters that reduce the voltage to the fan and thereby reduce its turnover. There are also so-called refuses or coolers controllers through which you can adjust the speed of rotation of any coolers.

Reobeas for coolers

When reducing fan speeds, it is important to monitor temperatures. Since there is a possibility of overheating. It may be necessary on the processor and video card in order to maintain the normal temperature with a reduced blowing.

Method No. 2. Replacing coolers on a quietest.

A more complex reduction in the noise level from the computer is to replace the existing coolers to better and as a result of a quieter.

New cooler

Replacing coolers on the computer case and on the processor is the easiest option. To do this, measure the size of the installation location and buy a new cooler of the corresponding diameter. When choosing a new cooler, it is best to take the most big fan.

In the case of a video card and power supply unit, the fan replacement process is a bit more complicated, since in this case it is more difficult to get to the fan. However, the cooler replacement process itself is no different. We determine the size of the fan, we buy a new one and install the old one.

If the replacement of fans is combined with a decrease in their revolutions, you can achieve a significant reduction in the noise level from the computer.

Method number 3. Disconnecting cabinet fans.

If the computer is used only as an office machine, then you can generally abandon body fans. Disconnect them and watch the temperature components of the computer. Most likely, the temperature will rise by about 8-15 degrees, but will remain in the tolerance limits.

Corrugated cooler

It should be noted that disabling enclosures only for computers used in office mode. If you work with heavy programs or play in computer games, it is impossible to disconnect the case fans.

Also, you cannot turn off the fans on the processor, the video card or power supply. Since this will lead to overheating of these components.

Method No. 4. Replacing a computer case.

Case replacement is also a good option. If you purchase a quality-absorbing material with a layer, you can significantly reduce the noise level from the computer.

Sound absorbing material on the cover of a computer case

Usually such housings from the box are equipped with high-quality coolers, so you do not have to look for suitable, buy them separately and independently install.

Today's question

Good day.

Tell me, I have a problem with a new laptop (he is 1 month). At night, I clearly hear the lightweight rumble when you run the game WOT (tanks) - the volume of the buzz increases, and with time the laptop is buzzing already as a tractor! It strains me very much, because It happens that relatives are already sleeping (and I get it difficult to ...).

Is it possible to somehow reduce the noise? For guarantees, I can't pass the laptop no longer, more than 2 weeks have passed after buying a device (it happened that I did not check the device completely, because I was leaving).

Alexey, Moscow.

Hello.

Alexey, I immediately want to say that noise-noise mint. Moreover, if there was no noise earlier, and now it appeared - this can signal the appearance of hardware problems with the device. In your case, most likely, when buying, you simply did not pay attention to the features of the laptop. Nevertheless, something can still be done.

In this article, they will raise the main reasons because of which the laptop may be noise, and what can be done with it ...

Immediately I want to say that in a laptop, much less mechanical devices were rather than in a PC, from which there may be noise. On the one hand, this fact helps to determine the source, on the other - in view of the compactness of the device is not always easy to eliminate the cause ...

Cooler. Probably the largest source of noise that is in most classic laptops. As a rule, if you do not load a hard device (i.e., you do not run games, viewing high-quality video, etc. Tasks) - then his work is almost silent. Although a small buzz is heard on some laptops, if you get closer to the side ventilation holes on the device case.

HDD. The most cunning source of noise. First, some models can easily skip and crack during operation (some models do it under load). You can only hear this noise in full silence (i.e., at night in silence, 100% will be annoyed). Secondly, this is not a warranty case, and in replacing the device for this reason will refuse you.

Also, at high load on the disk - can be heard as soon as a noticeable hum may be heard, like a cooler noise.

CD | DVD drive. It makes sufficiently strong noise when working: it goes like a root from the rotation of the disk and light crackle. By the way, many users simply forget to remove discs from it, and the laptop often spins the disk in the tray and noise appears.

Cause №1: Cooling system is clogged (if the cooler tahar)

Perhaps the most basic reason for which begins to bury it hard (or as many people say "taural") cooler is a large dust cluster that closes the ventilation holes, accumulates on the impeller and interferes with normal air circulation.

Due to dust, the cooling system does not cope with the load, the cooler begins to work faster, and as a result, noise increases.

Dust cleaning of the laptop Depends on its configuration. Some laptops will not be difficult to clean on their own even for a very novice user, others - to get to the cooler it will need to disassemble the entire device!

Therefore, look here: either in service, or an attempt to try to do everything on your own. His soaps and recommendations, how to do it, led in one of the articles (reference below).

Detail how to clean the laptop from dust on your own -

In general, 1-2 times a year is extremely desirable to led the cleaning of the device and remove excess dust. Not excess with this procedure will lubricate the cooler. If the inches of the impeller, periodically assisted about the housing (for example, it can be damaged during non-accurate cleaning) - it is easier to replace the cooler completely.

cleaning the impeller with a cotton wand

Reason # 2: High temperature and laptop load

Perhaps this reason partly intersects with the first. The fact is that the laptop cooler works dynamically - i.e. rotates at different points in time with different speed. The higher the temperature of the processor and the load above it is the load - the faster the cooler begins to rotate, in order to cool down more and time to divert heat. And such a work of the cooler in turn leads to the appearance of a hum and noise from a laptop ...

By the way, during this Gruty, when the cooler works at the limit, as a rule, hot air begins to go from the ventilation holes of the laptop. The keyboard can also become warm, it may not be comfortable to work (especially sin acer laptops on AMD processors).

And so, how to find out the temperature of the processor, the video card in the laptop?

The easiest way is to use a special utility - AIDA64 (reference to it is given below). To view the temperature of all components (CPU, video cards in AIDA64 hard disk etc.) - go to the tab "Computer / Sensors" .

The best utilities for viewing the characteristics of the computer (including AIDA64) -

Its modest view about what temperature I consider normal, and when you need to do something, told in this article: . I recommend to get acquainted!

1. use a laptop only on flat, dry, solid and clean surfaces (and many use a laptop lying on the sofa - and because of this, the ventilation openings may be overlap, which leads to overheating);
2. regularly (1-2 times a year) to clean the device from dust;
3. if you like to play games (as well as beam by heavy applications: video and graphic editor, etc.) - purchase a coolant coolant for a laptop. It is a way to reduce the temperature of 5-10 degrees (though pay attention, some of them are noisy ☺);
4. see if a large load on the CPU is connected with something else, and not just with launched game (I recommend to get acquainted with this article :);
5. also B. manual mode Customize the speed of rotation of the cooler (carefully! Do it step by step, does not hurry and watching the temperature) -
6. if you have very hot outside the window - try not to use a laptop in the sun, if possible, load it in the morning, evening hours when the temperature becomes below.

Reason # 3: Gul, crackling and handling from hard disk

Some models of hard drives, with their work, make mechanical noise: crackling and snapshoting. If the room is very quiet - then these clicks are very annoying. There is a similar due to fast movement Block with magnetic heads. Running forward will say that the speed of movement can be reduced due to which noise will decrease ...

How to reduce the noise level from the disk:

1. replace the disk to another (which is not noise). The best option is to install a SSD disk (he is a priori silent, because there are no mechanics in it), moreover, such discs are much faster! Comparison of the SSD disk and classical HDD, presented in this article:
2. check in task Manager (To call it - press the Ctrl + Alt + Del combination) - there is no application that loads your disk strongly (most often these are torrents, P2P programs for downloading files);
3. reduce head positioning speed using QuietHDD and HDDScan utilities. On how to do this, see this article -
4. if you have before hDD no noisy, and now began - this is an alarming symptom, I recommend checking the HDD -

Cause # 4: Forgot to remove the CD | DVD drive from the drive

CD / DVD drive is in many computers and laptops (although it does not put it at all). Because This is a mechanical device (like HDD) when the disk is promotion (especially for maximum speeds), it begins to buzz. Noise from it is stronger than from the actively working cooler.

If you forget to remove the disk from it - then each time you open the conductor (folders) - the drive will spin the disk, trying to provide you with information. As a result, noise will appear, and for 1-2 seconds. The computer will hide ...

I will give below what can be done and the reasons why the CD / DVD-ROM drive makes noise:

1. check if there is scratches on the carrier (disk), it is smooth? The victim disks are no longer no more;
2. you can try to install specials. utilities that can limit the speed of rotation of the disk, for example, Nero Drive Speed;
3. try to insert different discs: CD-R, CD-RW, DVD-R, etc. I also recommend trying to use licensed discs of a known brand, and not purchased in the transition in an unknown counter;
4. if there is a label on the disk - then the reason for it is possible, it can be unevenly applied (some thick labels can also affect the noise level of the drive);
5. noise in the drive may appear due to foreign objects, for example, a piece of a sloppy disk (if you did not have this, didn't you get into the drive?).

Cause No. 5: Not optimal BIOS work and drivers

Many underestimate the work of BIOS and drivers, meanwhile, they can have a big impact on the work of the laptop. As for noise - how you probably have already noticed - the cooler in the device works dynamically, i.e. The higher the load and temperature, the faster it rotates. This mode is enabled by default in BIOS laptop (Sometimes it can be customized, sometimes no). It is called, as a rule, like this: Q-Fan, CPU Fan. Control, Fan Monitor, Fan Optimize, etc.

In some versions of the BIOS, this cooler adjustment mode works out of hand bad - i.e. The cooler works much faster than it is required at the moment. In consequence, there are constant noise and hum of it (regardless of the load).

There are a couple of ways: Try to update BIOS (Caution! When updating - you can easily spoil the performance of the device) on more new version (if it is on the manufacturer's website).

Second output: Disable automation mode to BIOS and customize the operation of the cooler yourself with the help of specials. utilities. View an example, as is done, you can in this article:

I hope my modest advice helped get rid of "loud" noise and calm the nerves ☺.

For additions to the article - a separate MERSI.

On the sim all, good luck!

If you have a fan with a laptop when working with a laptop, then this instruction is designed specifically for you. In this article we will deal with why the fan is noise and what should be done to get rid of the annoying sound.

The reasons

There are several obvious reasons why Laptop is very buzzing:

• Overheating and, as a result, the high speed of rotation of the blades of the cooler, which leads to high level noise.
• Dust and dirt in the cooling system, which interfere with its full and uninterrupted operation.

Everything is quite simple, but there is a couple of nuances. For example, if your device is very noise, only when certain games or programs are included, then you should not worry and make any actions, as it is quite normal.

All that is needed in this situation is preventive actions every six months in the form. If your laptop is very noise when the non-loading computer program is running, it is worth trying to do something.

What actions can be taken

There are several options for troubleshooting data:

• Cleaning from dust and dirt;
• BIOS update;
• Application of the program to change the speed of the cooler;

Cleaning from dirt and dust

If the cooler in your laptop has become very skin and overheat, then it may mean its excessive contamination. It is recommended to regularly clean the laptop, but it is not necessary to carry it at all service centerAfter all, everything can be done at home.

If you decide to clean the laptop yourself, you need:

If there was a lot of dust in the device, then after cleaning you will immediately notice a positive result: the computer will warm up less and much quieter. However, prevention does not always help, for example, when the mechanism is depreciated, in this case it may be complete.

BIOS and Drivers Update

Developers often produce driver and BIOS updates, which have previously needed errors. It is in BIOS that the temperature of the sensors and the speed of rotation of the blades of the cooler is set. Therefore update software Can help eliminate fan noise.

Sites with the necessary drivers for users of the most popular models:

• Acer.;
• HP.;
• Toshiba;
• Lenovo.;

Changing the speed of the cooler

If the fan is too much noise in the laptop, then maybe it will help you special program Speedfan, which will change the speed of turns of the blades. She gets all necessary information From the temperature sensors, which is equipped with your laptop, and makes it possible to take into account the data obtained. Adjusting the indicators correctly, you can remove the noise of the cooler by limiting the speed of its rotation.

If the processor temperature rises too high, then the program in automatic mode Run the fan to full power to ensure the protection of the laptop from overheating. Therefore, if the laptop began to noise after the settings you made, then there is nothing terrible.

How to prevent the appearance and reduce the noise of the laptop?

Now you know how quickly and without any problems to reduce the fan noise yourself at home, and you can help not only yourself, but also to your friends and friends.
