What happens when the fan buzzes when the computer is turned on, and the laptop fan buzzes?

This is because the cooling fan is short of oil, which will cause the sound of dry grinding.

Try to clean the dust off the fan before refueling, and consider refueling if the effect is not obvious. Don't add cooking oil, common engine oil for bicycle repair, sewing machine oil, etc. are OK. Let's talk about how to add it, first of all, tear the sticker on the fan shaft, and then use a small screwdriver or small tweezers to pry open a small rubber plug in the middle, you can drip oil into the shaft, don't add too much, one drop is enough.

Attach the rubber stopper again and put the sticker on your back back to its original place. If the sticker is no longer sticky, you can use a small amount of glue to stick it. Turn the fan and let the oil seep in.

After a few seconds of fan rotation, the oil enters the metal hole and then into the bearing, and you notice that the fan is spinning faster and quieter than before. However, the method of adding lubricating oil is not a panacea, and it is better to replace the fan if it has been used for too long.

Learn more about the causes of fan noise and how to deal with it.

Here are a few details about filling the fan with oil:

If you use sewing machine oil or engine oil.

Sealing problems after oil injection.

Solve this problem with a thorough analysis.

An excessively loud fan may be caused by too much dust accumulation on the fan, so you can remove it and clean it up or consider replacing the fan.

As long as it's not the CPU and graphics card's fan, the other fans can be unplugged and won't be so noisy.

Maybe it's been a long time. When there is a lot of dust in the fan blades, there will be a sound of asking. I've had it before. Take the case apart、Just wipe it with a dry cloth strip、Hope。

If the fan is aging or there is too much dust, the solution: remove the fan to remove the dust.

Reason 1: There are many reasons why the fan is loud, and we need to eliminate it step by step. Let's start with the software.

If the high temperature continues, then it may be that there are a large number of programs running in the background of the computer, resulting in the high heat generation of the CPU running at high speed, and the fan must be maintained at a large wind speed to achieve the purpose of heat dissipation.

Reason 2: The cooling fan is damaged, the fan will gradually wear out after a long period of use, or due to the lack of oil in the bearing, it will make the fan produce a loud sound when it rotates. Moreover, due to the low degree of fineness of workmanship, the center of gravity of the fan blades will deviate from the center of gravity of the fan blade, which will cause the fan to be abnormal.

Reason 3: After the computer is used for a long time, it will accumulate a lot of dust on the fan blades, which will increase the load of the fan and reduce the speed, in order to achieve the standard air supply volume, the fan will rotate at a higher speed, causing the fan to be abnormal.

It is normal for the laptop's fan to produce a certain sound when it is working because of the rotation of the fan and the flow of air.

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 contact the official after-sales service for testing.

The main ones that make such sounds are CPU fans, graphics card fans, power supply fans, etc.

1. The computer host has not been cleaned for a long time, and there is too much dust.

2. The cooling fan has no lubricating oil or the lubricating oil is very viscous, which will have a great impact on the fan, resulting in a loud sound.

3. If the computer fan in the case is not installed firmly, the vibration of the fan when the fan rotates will cause the case sound to suddenly become louder, so it is recommended to tighten the fans of each radiator, and it is recommended to check whether the cable in the case is reasonable.

4. The resonance of the radiator can also produce noise, but not every computer will produce resonance noise, and the way to eliminate resonance noise is actually very simple, adjust the placement of the chassis or add some soft cushions. It is not a good idea to add sound-absorbing cotton to the inside of the case, which will often affect the heat dissipation of the case.
