Our daily work, study and entertainment are inseparable from the computer, desktop and laptop although the degree of portability is not the same, but its functions and parts are also similar. There are fans inside the computer to play a role in heat dissipation, but after a long time with the computer, the sound of the computer fan will be particularly loud, and even affect the original volume of the computer, so what is happening in this case?
A computer fan sound how to do
1. Clear the dust on the fan
Dust is one of the major causes of increased fan noise, because the ubiquitous dust will always enter the not completely sealed casing. When the CPU fan rotates at high speed, the vortex effect makes the dust easy to attach to the fan. For desktop computers, remove the side cover of the case and use professional dust removal equipment to remove dust; use a soft brush and duster for laptops to clean the cooling fan.
2. Add lubricant
The fan bearings are used for too long, the fan coil is aging, and the lack of oil will cause the sound to become louder. You can add lubricating oil to this position, and it is recommended to use mechanical lubricant or gasoline engine oil. Of course, you must be careful not to spill the lubricant when adding it.
3. Reduce the ambient temperature
High ambient temperatures in summer cause the cooling fan to continue to run at high speed, thus making the sound louder. If you do not want to disassemble the computer in order to clean the dust, you can use it in a cool air-conditioned environment in summer. Then you can buy a cooling base and other auxiliary cooling devices.
Second, how to solve the sound of computer chassis
1. check whether the alignment of the chassis is reasonable, if the cooling fan is encountered, you can rearrange the alignment;
2. tighten the screws used to fix the computer fan, so as not to loosen the computer fan, thus making a lot of chassis noise;
3. regularly remove the dust accumulated in the chassis, especially on the computer fan must be cleaned up, and can be used to remove it with a small soft brush.
Third, the laptop fan how to clear the dust
First, remove the external power supply and battery of the laptop computer, and make sure that the power is cut off. Then, remove the screws on the fan housing of the laptop computer, and then remove the housing.
At this time, you will see a lot of adsorbed dust inside the casing, please use a rag to wipe the casing first, and then wipe the dust on the surface of the fan.
3. Unscrew the laptop fan fixing screws, first cover the board with paper towels, then wipe the dust on the fan with a cotton swab dipped in a small amount of water, then use tweezers to remove the large blocked fiber dust, then clean the air outlet.
4. First cover the circuit board below the air outlet with paper, then use a cotton swab dipped in a small amount of water to gently stick the dust on the fan outlet, and finally use the swab to wipe off the dust on the surface of the circuit board.
5. After cleaning, install all the removed screws, first fix the fan with two screws, and then fix the four screws on the back cover.
