Computer power supplyCooling fanNoise treatment methods are as follows:

First, clean up the dust.

1 We need you to take down the power supply (as long as the four screws connected to the power box behind the host are removed, the power box can be taken out), and prepare medium-hard brushes, air pumps or hair dryers. In order to prevent the static electricity on our hands from damaging the power supply, it is recommended to hold a large metal object, such as a metal railing.

We need to hold a hair dryer in one hand to blow at the fan and a brush in the other hand to comb the dust. it is recommended that everyone wear a mask. there will be more dust. if the fan blades can be removed, it is best to clean them up with clean water.

The host is not only cleaned up the power supply fan, but also the processor and graphics card fan.

Second, oil the fan. The fan has no lubricating oil or the lubricating oil is very viscous, which will have a great impact on the fan and produce a loud sound.

Refueling is very effective in eliminating the noise of the fan. Remove the fan and stick a sticker disc in the center of the fan on the side of the heat sink. Picking up the wafer, you can see the fan shaft. If the inside is relatively clean, it is enough to directly drop a drop of light lubricating oil. If it is found to be dirty, it is necessary to remove the rotor for cleaning. It can be found that there is a stopper at the end of the shaft. Carefully remove the stopper and the rotor can be removed for cleaning. Clean can use gasoline or anhydrous alcohol, wipe clean, wait for complete drying, and then add oil to reset the rotor. Finally, stick a sticker wafer, and you can install the heat sink.

Some fans can tear off the label on the fan to refuel, but some fans can't, can only remove the blades, take out the bearing to refuel. Use liquid oil such as sewing machine oil; There are others, such as butter, etc., which can sometimes be mixed and used with better oil if conditions permit.

Third, sometimes the power screw is not tightened, it will also produce resonance, resulting in slight noise. It is recommended to check that the power supply is stable and suitable for even installation.

In the last step, we should not forget to clean the dust on the power supply shell and chassis dust-proof net. Just like cleaning the fan, use an air pump and brush to clean while blowing. The dust-proof net can be removed and cleaned best.
