The sound of the computer fan, the squeak of the computer fan, what s going on

What a cup, it's not a fan, if there's a problem with the fan, I'll keep thinking about it, the landlord is talking about the hard disk, because of the sound when reading and writing, the hard disk you've used for a long time, you have to clean up more than the junk files, and the C drive, try not to apply.

Abnormal. Generally speaking, the computer's fan is a little louder when it is turned on, and it will be normal after a while.

There are two possible reasons why your fan is loud and quiet.

One is that there is friction between the fan blades and the plug-in cables in the chassis, even if the chassis is not motivated, this situation may also occur.

The second is that there is a lot of dust on the fan blades, which should be cleaned up.

Whatever the reason for this situation, it should be checked and cleaned up, and don't underestimate this fan.

It should be the cooling fan of the CPU, unplug the CPU fan and clean it up, put the lubricating oil on the shaft in the middle, and the CPU will be better if you have a little silicone grease on the picture above, it is normal to have a sound, and the sound depends on how well you maintain it.

No big problem, add some clock oil to the fan.

See if the cable in the computer has hit the fan. If you don't add less oil to the fan! It should be the first case!

It may be that the fan blades have touched the line.

Try to keep your computer in a ventilated place, as it needs to dissipate heat!

I guess the CPU is overheating. Take it apart to see if the fan is dirty. Or scrape the line inside. It shouldn't be a big problem.

As long as it's not a hard disk, the optical drive is generally no problem, and the fan is very loud when you are pregnant, and the sound is generally not too loud due to cooling and speed regulation.

The most important component of lubricating the bearing fan is the bearing, which lacks lubricating oil for a long time. In addition, poor quality cooling fans are used for polishing fan blades, and due to defects in the process of making this type of fan, the center of gravity of the fan blade may not be on the axis, forming an "eccentric".

In general, the speed of the fan is indicated on the manual of the radiator. Generally speaking, 30% of the heat dissipation effect of a radiator depends on the speed of the fan. But the higher the fan, the better.

The correct fan speed should be determined according to the heat generation of the CPU, and the speed selection of fans of different specifications should be differentiated, the basic principle is: under the premise of generating the same air volume, the larger the fan speed, the lower the speed, and the noise will also be smaller, generally between 3500 rpm and 5200 rpm is more conventional.

The higher the power, the stronger the fan and the better the heat dissipation. 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. Generally, the best fans in the computer market are DC 12V, and the power varies from W to W, so the power needs to be selected according to the CPU heat.

If the power is too large, not only will the cooling effect not be greatly enhanced, but it may increase the workload of the computer, and ultimately shorten the life of the CPU and fans. Therefore, when choosing the power of the CPU, you should measure the "heat". And the opening in front of the fan should be kept clean at all times to avoid blockage.

Question: My computer was looking for a ** store to reinstall the system, and now I have used it for a while, and the computer suddenly drops frames, that is, not only the game drops frames, but also the normal system uses a bit of frames, and the fan has a sound of bang, I wonder if there is a problem with heat dissipation.

Ask questions, they are only responsible for reloading, basically if there is a problem, let me reload, I think of other ways to solve it.

The main question is that the computer is dropping frames, and I suspect that there is a problem with the fan cooling because he has been dissipating heat, and there are strange sounds.

Answer: It is recommended to clean up the dust, you can do it yourself, or you can go to the repair shop to clean the dust. If it still doesn't work, it is recommended to install a temperature monitoring software, such as Master Lu, to detect the temperature of the hardware device, if the temperature is low and the fan is still running, it is recommended to enter the BIOS to check the fan running temperature setting, if it is too low, you can increase the temperature appropriately (many of these are automatic, only some models can be adjusted). In other ways, you can also buy a cooling base or an exhaust radiator to increase the internal heat dissipation capacity of the laptop and reduce the operation of the laptop's own fan.

Ask if you need to remove the back cover to clean up the dust.

The rotation of the fan is related to the temperature of the CPU, such as the ambient temperature is high, the running of too many programs or the CPU occupancy is too high, which will cause the CPU temperature to rise, and the fan will rotate more frequently when the CPU temperature increases.

It is recommended to clean the ash, or check if the fan is faulty and replace the fan.

That's because of the aging of the fan, the lack of lubricating oil between the stator and the fan, resulting in abnormal noise, you can disassemble and carefully clean the fan, add some lubricating oil appropriately, first of all, you have to be able to disassemble and assemble! Otherwise, it will cause destruction!

If your computer is assembled, the quality of the fan is not up to par, and the fan shaft is grinding off.

Computer fans include: power supply fan, CPU fan, graphics card fan, and case cooling fan, make sure that the fan is squeaking.

There is a problem with the fan bearing, if the sound is not harsh, and the computer has not crashed for no reason, the temperature is high, just bear with it!

If you really can't buy a good one - such as Cool, or other brands.

As long as you are not an audiophile, all fans made by regular manufacturers are fine.

The fan is aging... I suggest you go and change the fan.

Reasons why laptop fans are loud:

1. If the use time is too long, the coil of the fan is aging and there is a lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The position of the fan is offset due to excessive dust accumulation or loose fixing screws.

4. Power supply problem.

1. Remove dust

Generally speaking, newly purchased fans are always less noisy, and they become significantly louder after a period of use. In fact, dust is one of the main causes of fan noise, because pervasive dust can always penetrate into a chassis that is not completely sealed. When the CPU fan spins at high speeds, the vortex effect makes it easy for dust to adhere to the fan.

There is no doubt that it is necessary to remove the CPU fan and clean it properly at this time, and when removing dust, everyone should pay attention to the gap between the back of the fan and the heat sink, which is the easiest to forget.

2. Add lubricating oil

For fans with oil-impregnated bearings, it is not uncommon for the motor shaft to become inflexible after a long period of operation. For this reason, it is recommended that you add lubricating oil to this location, and it is recommended to use mechanical lubricants or gasoline engine oil. Of course, care must be taken when adding lubricating oil and never allow it to spill.

3. Reduce vibration

In addition, the vibration problem also needs our attention, usually the high-speed rotating fan will have a high-frequency collision with the heat sink, if the fan and the heat sink are stable and appropriate, the vibration and noise caused by the collision can be greatly reduced. For example, holding a CPU fan that spins at high speed in your hand is much less noisy than holding it to a heatsink because the soft human hand absorbs a lot of vibration. According to this principle, adding a 1 2 mm thick soft gasket (such as leather and rubber) between the four corners of the fan and the contact surface of the heatsink can effectively reduce the noise caused by the vibration of the fan and the heatsink.

What should I do if the laptop fan is loud and low?

In the process of using the notebook, the sound is sometimes loud and small, many people are worried about whether there is a fault problem, in fact, if it rings every once in a while, it is normal, mainly because the laptop heat dissipation is not good, so the CPU fan will make a sound when it is cooling. However, if it is a short interval and continuous ringing (about 2 times in an average of 2 minutes), it is not normal, and it may be that there is a problem with the graphics card driver, and the heat dissipation is large, and it needs to be dealt with.

Laptop fan is loud, generally speaking, the most important thing is the problem of dust accumulation, but there is also a situation of aging and lack of oil in the first circle, which requires everyone to check and eliminate their own computers, if you really can't deal with it, you can find the personnel of the maintenance center for help.

After the computer has been used for a long time, there will be a lot of dust inside the computer, which is the main reason for the loud fan, so if there are conditions, it is best to clean up the dust inside the computer after a certain period of use, which can make the computer run more smoothly.

What should I do if the desktop CPU fan is too loud? How do I reduce the sound of a desktop computer CPU fan turning? Let me briefly introduce it to you!

Workaround:

1. Let's take a look at the front of the CPU fan first.

2. There is also the back.

3. Remove the non-sticky paper on the back of the CPU fan.

4. After that, we can see a round iron buckle.

5. We use a smaller flathead screwdriver to gently buckle the iron buckle. Pry it off (note: don't break the iron buckle).

6. Look at the back of the CPU fan after the buckle is removed.

7. Then we remove the main structure of the fan from the front of the CPU fan.

8. Below is the main body of the fan blade that has been removed.

9. After removing the main body of the fan blade, you can see the motor part, which is the main component of the CPU fan rotation.

10. The main body of the fan housing on the back.

11. In the middle of the motor (on the roller), we smear some butter or other roller lubricating oil.

12. After that, touch the middle of the shell a little, not too much, touch it, and distribute it evenly with a paper towel or brush.

13. Reinstall the main structure of the fan, and then use it on the hole in the center of the back of the CPU fan (don't forget to buckle it!) Tape encapsulation.

14. Put it back on the CPU, turn it on and listen, is it much quieter?

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, please feel free to use it. The rotation of the fan is related to the temperature of the CPU, such as the ambient temperature is high, too many programs are running, or the CPU usage is too high, which will cause the CPU temperature to rise, and the fan will rotate more frequently when the CPU temperature rises.

1. In this case, there are generally the following two situations:

1. The fan will run at full speed when the computer is turned on, and the noise will be louder when it is just turned on.

2. The dry and astringent lubricating oil of the fan does not play a lubricating role, and the friction between the fan spindle and the lubricating oil will dilute the lubricating oil, and the diluted lubricating oil can play a lubricating role.

2. Solution:

This kind of problem will occur when the computer has been used for a certain number of years, it is the lack of lubrication of the fan bearing, you can remove the computer cooling fan, there is a place on the fan that is sealed with adhesive tape, take off the adhesive tape, you can see the ball bearing of the fan, add one or two drops of lubricating oil to it, and reinstall the fan.

The fan rings due to the cold weather, and the lubricating oil (butter) in the fan is not soft enough, resulting in abnormal noise, and the machine will heat up after a break in time. If the sound persists after the computer is turned on for a period of time (after the machine heats up), it is recommended to clean the fan. Otherwise, the fan is broken and needs to be replaced.

Maybe it's broken, or it'll be fine in a few days.

There is a problem with the fan and it needs to be replaced.

Generally, the fan life is the worst, but it can operate normally for more than a year.

There are two reasons for this.

1.The fan is a variable speed fan, and when the CPU temperature is high, the speed automatically increases, and the noise becomes higher. When the landlord first bought it, he had less chance of running a large 3D game. Later, when I was playing, I felt the sound getting louder.

2.There is a little bit of a psychological effect.

Solution: Replace a dedicated silent fan.

Try to place the case away from you (it sounds dirty, but it actually works).

After opening, there is a card on the shaft, use a small screw, gently pry it, and open it. The fan can be pulled out, and then greased, preferably with some pencil foam in it, for unexpected effects. After two years, it won't ring.

Then it is loaded and sealed with hot melt adhesive.

Later lubrication of the fan requires a special low-viscosity synthetic lubricant.

Most of the well-known electric fan factories such as Beriaco use fully synthetic electric fan lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless, low temperature resistance, no dust. Tao has a 120 ml white needle-nosed small oil bottle, drop a few drops, easy to use.

It is not advisable to use ordinary engine oil and butter, which will volatilize quickly in summer and will have an unhealthy smell.
