Computer fans are loud, why are computer fans so loud

1.The ambient temperature is low in winter, and the general power supply fan is louder when starting, and the sound gradually decreases after preheating. CPU fans are less affected inside the case. In addition, in winter, outdoor personnel activities are reduced, the outside noise is reduced, and the noise of the chassis is increased.

2.The reason for the loud fan may also be that there is a lot of dust. For CPU fans can be removed and cleaned with a small brush, including the heatsink.

It is best not to refuel the CPU fan, there is a certain chance that it will affect the power supply and cause damage to the motherboard. In addition, the original fan generally runs very stable after cleaning, and the sound is smaller. If you use a non-original CPU fan and the noise is still loud after cleaning, it is recommended to replace the brand fan, and you get what you pay for.

For the power fan, you can remove the power supply and turn it on for cleaning, which is very simple. Be careful not to use brute force to avoid desoldering of the solder joints of the internal components. In addition, you can turn on the power fan for refueling, tear off the label and open the leather cushion and use watch oil or sewing machine oil to add two drops, and pay attention to wipe the excess oil on the fan after adding.

3.In addition, the silica gel on the contact surface of the CPU fan and the CPU under the CPU should be thinly wiped evenly, and the grooves on the heat sink should be filled to make them in good contact, which can improve the heat dissipation performance, so that the CPU fan speed will not be too high, and the sound will naturally decrease.

4.In general, in a relatively clean home environment, the chassis should be cleaned once a year (like people, it will take a year every year :) You can use a hair dryer (note that you can only use the cool breeze block, not hot air on the motherboard and other components), leather tigers, etc., you can borrow an electric sootblower if you have the conditions, and after cleaning, the sound will be much smaller.

You might as well give it a try.

5.In addition, fix the screws of the chassis panel, etc., firmly hold the chassis against other objects, and put some leather pads underneath to reduce the vibration of the chassis, which can also have a certain noise reduction effect.

Sometimes it's good to reinstall the system.

Summary. The reasons for the loud sound of the computer fan are as follows: 1. The layout of the cable in the case is unreasonable, and the computer fan touches the cable when it rotates, which causes the problem of large noise in the case; 2. The computer fan in the chassis is not installed firmly, and the vibration occurs when the fan rotates, resulting in a sudden louder sound of the chassis; 3. If there is dust accumulation in the case fan, and the resistance of the fan increases when it rotates, the computer fan will be loud. 4. The last one may also be caused by viruses and Trojans, the current computer fans are basically automatic temperature control fans, if the computer is poisoned, the CPU occupies extremely high and causes the CPU to heat up, then the computer fan will automatically speed up the rotation speed to reduce the CPU temperature, this situation may also lead to the computer case loud.

Why are computer fans so loud.

The reasons for the loud sound of the computer fan are as follows: 1. The layout of the cable in the case is unreasonable, and the computer fan touches the cable when it rotates, which causes the problem of large noise in the case; 2. The computer fan in the chassis is not installed firmly, and the vibration occurs when the fan rotates, resulting in a sudden louder sound of the chassis; 3. If there is dust accumulation in the case fan, and the resistance of the fan increases when it rotates, the computer fan will be loud. 4. The last one may also be caused by viruses and Trojans, the current computer fans are basically automatic temperature control fans, if the computer is poisoned, the CPU occupies extremely high and causes the CPU to heat up, then the computer fan will automatically speed up the rotation speed to reduce the CPU temperature, this situation may also lead to the computer case loud.

The solution is as follows: (1) Clean up the dustAfter a long period of use, the computer will absorb a large amount of dust. The fan is the heat dissipation part of the computer, and if the dust accumulates too much, it will not only cause loud noise, but also affect the heat dissipation performance of the computer! At this point, ash cleaning becomes a must.

2) Replace the fan due to the quality problem of the fan. The fan is old, or there is a problem with the sash page. If the computer doesn't heat down well, the fan will spin faster, resulting in a very loud sound.

When this happens, you have to replace the fan with a new one. Try to choose a silent fan. (3) Check the layout of the wiring and re-deploy the layout in the computer case, or the fan screws are not installed firmly, check and reinforce.

4) Replace the antivirus software Win10 has built-in Windows Defender antivirus software, which is a good design for netizens who usually don't like to install antivirus software manually. However, the system usage of Windows Defender is a bit high, especially for some low-configuration computers, the CPU soars and the running lag is often directly related to Windows Defender. In fact, we can install a set of low-occupancy antivirus software for win10.

Windows Defender system consumption is very large adjustment method: directly install third-party antivirus software, win10 will automatically close the built-in windows defender.

Hello dear, the above is why the computer fan is loud and how to solve it, for your reference <>

1. The layout of the cable in the chassis is unreasonable, and the computer fan touches the cable when it rotates, which causes the problem of high noise in the chassis; 2. The computer fan in the chassis is not installed firmly, and the vibration occurs when the fan rotates, resulting in a sudden louder sound of the chassis; 3. If there is dust accumulation in the case fan, and the resistance of the fan increases when it rotates, the computer fan will be loud. 4. The last one may also be caused by viruses and Trojans, the current computer fans are basically automatic temperature control fans, if the computer is poisoned, the CPU occupies extremely high and causes the CPU to heat up, then the computer fan will automatically speed up the rotation speed to reduce the CPU temperature, this situation may also lead to the computer case loud.

It should be a problem inside the fan, which can be disassembled and dealt with as follows:

1. First remove the fan from the case, and you will find a sticker on the back.

2. Use tweezers to remove the post. Some fans have stickers on both sides, and I don't know which side is sealed, so let's uncover both sides.

3. After uncovering, it is found that there is a bearing in it, and if you look carefully, you will find that there is a small retaining ring. Many friends may inject lubricating oil into the fan at this step. This often does not play a role, the small retaining ring plays a sealing role, and the lubricating oil basically does not have much to enter, and the lubricating oil volatilizes quickly.

4. Carefully remove the retaining ring with tweezers, do not use brute force.

5. These steps are to remove the dust on the fan blades, and it is recommended to clean them with a vacuum cleaner and a small brush if possible.

6. Lubricating oil is a liquid lubrication product, with strong fluidity and easy volatile. The lubricant can firmly produce a layer of lubrication ring on the bearing, which is not easy to volatilize, can produce a long-lasting lubrication effect, and effectively reduce the fan noise.

7. Let the bearing show sufficient contact lubricant to achieve the purpose of lubrication evenly.

8. If the uncovered self-adhesive is glued on, it will not be too sealed. Therefore, we can make a new sticky sheet, which can effectively achieve the purpose of sealing and reduce volatilization.

9. Install the fan on the main unit and try again. The noise has decreased a lot, and the world is finally quiet. Some fans may not have a small retaining ring, so it is very convenient when disassembling.

However, be sure to inject lubricant or oil into the bearings and copper rings, and finally stick the stickers. In this way, the lubrication purpose can be achieved in a sustainable manner.

1. The power of the fan is directly related to the speed of the fan, that is to say, the higher the speed of the fan, the more powerful the fan. At present, the best fans in the general computer market are DC 12V, and the power varies from W to W, so the power needs to be selected according to the heat generated by your CPU.

2. Special reminder is that you can't emphasize high power one-sidedly, you only need to match the power of the CPU itself, if the power is too large, not only the cooling effect is not much enhanced, but it may increase the workload of the computer, and ultimately shorten the life of the CPU and fan.

3. Therefore, when choosing the power of the CPU, it should be measured "hot". And the opening in front of the fan should be kept clean at all times to avoid blockage.

When the fan is working, it will produce a certain sound due to the rotation of the fan and the flow of air, which is a normal phenomenon. The rotation of the fan is related to the temperature of the CPU, such as the use of high ambient temperature, too many running programs or large software will cause the CPU temperature to rise, when the CPU temperature increases, the fan will rotate more frequently, and the sound will be louder. If the sound is particularly loud or you feel that it is abnormal, it is recommended to go to the nearest official service center to test and confirm, and it is better for the engineer to test it on site.

The computer cooling fan is loud, mainly due to these reasons and solutions.

What to do if the computer fan is loudThe first is that the fan is clogged with dust, so just clean it up.

Second, the shaft of the fan is rusty, just lubricate it with oil.

Thirdly, the eccentricity of the fan blades is the main cause of high noise, so it is necessary to reinstall the fan firmly.

Fourth, if the fan scrapes any foreign objects, disassemble and check them, such as removing foreign objects.

Fifth, the configuration of the computer equipment is not high, resulting in a large power and louder sound during the boot period, and the computer will be fine after a period of time.

Finally, if it is not for these reasons, there is a problem with the hard drive, and you need to check the hard drive.

Our daily work, study and entertainment are inseparable from computers, although the degree of portability of desktops and laptops is different, but its functions and parts are also similar. There are fans in the computer, which play a role in heat dissipation, but after the computer is used for a long time, the sound of the computer fan will be very loud, and even affect the original volume of the computer, so what is going on in this situation?

1.Remove dust from the fan Dust is one of the important reasons for increasing fan noise, as the ubiquitous dust will always get into the enclosure that is not completely sealed. When the CPU fan spins at high speed, the vortex effect makes it easy for dust to adhere to the fan.

For desktop computers, the side cover of the case can be removed to remove the dust with professional dust removal equipment; Use your notebook's soft-bristled brush and dust collector to clean the cooling fan.

2.Add lubricating oil If the fan bearing is used for too long, the fan coil unit will deteriorate, and the lack of oil will cause the sound to become louder. Lubricating oil can be added to this location, it is recommended to use mechanical lubricant or gasoline engine oil. Of course, care must be taken when adding lubricating oil and never allow it to spill.

3.Lower the ambient temperature The ambient temperature in the summer is very high, causing the cooling fan to continue to run at high speeds, which makes the sound louder. If you don't want to disassemble your computer to clean up dust, you can use it in a cool, air-conditioned environment in the summer.

You can purchase auxiliary heat dissipation devices such as cooling bases.

1.Check whether the wiring in the case is reasonable, and if you encounter a cooling fan, you can rearrange the wiring;

2.Tighten the screws used to secure the computer fan so that the computer fan does not come loose and thus make a lot of case noise;

3.Regularly remove the dust that has accumulated in the case, especially the dust on the computer fan, which must be cleaned and removed with a small soft brush.

1.First, remove the laptop's external power supply and battery, and make sure to cut off the power supply. Then, remove the screws on the laptop fan casing and then remove the casing.

2.At this time, you will see a lot of adsorbed dust inside the case, please wipe the case with a rag first, and then wipe off the dust on the surface of the fan.

3.Unscrew the set screws of the laptop fan, first cover the circuit board with a paper towel, then wipe the dust off the fan with a cotton swab dipped in a small amount of water, then use tweezers to remove the large pieces of blocked fiber dust, and then clean the air outlet.

4.First, cover the circuit board under the air outlet with paper, then use a cotton swab dipped in a small amount of water to gently stick the dust to the fan air outlet, and finally use a cotton swab to wipe off the dust on the surface of the circuit board.

5.After cleaning, install all the removed screws, first secure the fan with two screws, and then attach four screws to the back cover.

Here's how to deal with a loud computer fan:

1. If you are facing a loud fan caused by a cable problem, we can open the case and rearrange the cables in the case.

2. If we are faced with a loud fan caused by the computer configuration, then we need to upgrade the computer, such as changing the computer power supply, CPU, graphics card, etc.

3. If the fan is loud due to dust blockage, then we can also open the computer case and use a vacuum cleaner or brush to clean up the dust accumulated in the case.

The reason why the computer fan is loud

1. Wiring problems.

The loud computer fan is most likely due to a problem with the wiring of the computer case. The wiring of the computer case is messy, and the fan touches the noise of the cable next to it when it rotates.

2. Computer configuration problems.

When running some games or software with high computer configurations, the computer is running at full load, and the heat generated is high, and the fan needs to be selected faster to dissipate heat, which will also cause the fan to become louder.

3. Dust blockage.

In the computer case, if dust accumulates on the computer's cooling fan, the fan will also make a louder sound when it rotates because of the dust in the process of computer heat dissipation.
