The CPU fan is loud when it is turned on

The cleaning of the sash does not affect the noise of the fan. Pour lubricating oil into the bearings of the fan. If you want to change the fan, you can buy a fan according to the type of CPU. That is, tell the fan seller that the type of CPU you have is fine.

The computer will automatically adjust the speed of the fan to the highest when it is just turned on, and the fan can quickly reach the maximum speed and start working, which is normal, it sounds like pressing the power button, and soon I hear a loud fan noise, and then slowly disappear.

If the system works under high load for a long time, the CPU temperature rises, and the fan will also start to spin at high speed, producing noise.

There are two conditions that will cause the fan to rotate at high speed for a long time;

1.The speed control function of the motherboard or fan is invalid.

A damaged card slot causes the CPU to overheat continuously, so the fan doesn't stop.

The maintenance method is not complicated, but it is best to find a professional person or DIYER to help.

The above is a personal opinion.

CPU with a fan, right?

Let's get a better fan, but AMD's fans are guaranteed. It can be repaired, but it takes time.

Clean up the dust, put some oil on it, but I don't know if you're going to get it.

The easiest way to do this: change the fan.

It is recommended to change to a new one, if you don't want to change, clean it up yourself, but be careful, he is very expensive.

There are several reasons why CPU fans are loud:

1. The computer runs a lot of programs, the CPU workload is large, and it needs to dissipate heat, so the fan speed is very high and the sound is very loud;

2. If the vent is blocked, if the air flow of the vent is not smooth, the CPU will not be able to dissipate heat well, resulting in the fan needing to rotate at high speed to take the heat away;

3. There is a lot of dust inside the computer, resulting in poor heat dissipation, high-speed rotation of the fan, and loud sound;

4. The CPU fan has been working for a long time, and the sound is loud due to lack of lubricating oil.

Solution: 1. Remove dust.

Generally speaking, newly purchased fans are always less noisy, and they become significantly louder after a period of use. 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. 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. 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 so that it does not spill.

4. Check the layout of the cables.

Reconfigure the layout of the computer case, or the fan screws are not installed firmly, just check and reinforce.

5. Computer housekeeper is a comprehensive anti-virus.

The main cases are as follows:

Some computers may not have a high configuration of the equipment, and the sound is relatively loud when it is turned on, and it will slowly become smaller later, which is a relatively normal phenomenon.

If the fan is still loud after a long time, it may be that the shaft of the fan is rusty, you can apply less oil on the shaft and lubricate it.

It may also be because the fan has scratched something, you can open the fuselage to take a look.

Dust behind fan blades and radiators should be cleaned frequently.

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

If none of these can solve the problem, it may be that there is a problem with the hard drive, and you can find a professional to see.

If you want to make the sound high, just go to the BIOS control interface, find the CPU Fan option, and turn the speed down. Generally, non-original fans run at full speed by default, and there is another situation that the fan rotates wildly when it is turned on, and it slows down normally after turning on, which is a protection setting, and the full-speed operation before booting can blow off the dust stuck to the heat sink, which is conducive to better heat dissipation.

Newly bought and didn't use it much, it should be that there is a problem with the quality of the fan itself, send it to the after-sales maintenance point to take a look, and add a ghost oil.

The sound is loud, it is two conveniences, one is that the time is long, the weather is cold, and the run-in place needs to be refueled, if you want to add, take off the fan, turn it over, and add some lubricating oil to the middle bearing.

It may also be that there is a problem with the handover place.,Then it's going to be a bad one.,The fan below i3 is about 20 yuan.,It is recommended to change to a new one.。

If there is a problem with the quality, it will affect the CPU heat dissipation!

No, it should be louder when it is turned on, and then it will slowly decrease.
