The old computer many years ago was very noisy. What is the reason? The reason is as follows: CPU fan is the biggest noise source of the old computer. It used to be quiet, but after a few years, it became noisy and disturbing. As the owner, let me solve the problems. Follow Xiaobian to see what makes it so noisy.

CPU fanThe reason why the noise is so loud is that a thick layer of dust accumulates, which increases the noise in two ways.

1. The dust hinders the rotation of the fan, and friction produces noise.

2. The dust hinders the CPU's heat dissipation. The fan must run faster to dissipate heat.

Years of dust can be terrible.

The first thing we do is clean up the dust. Take out the fan from the CPU. Note that there are four compression springs on the fan, and each spring has a clip:.

Just turn it in the direction of the arrow on the pressure spring and pull it upwards. If so, the fan can be removed. Use a small brush to remove dust and dust from the fan and dust cover of the chassis.

After reinstallation, we can also confirm whether the intelligent fan control or Q-Fan control in the BIOS is turned on (different motherboards have different names):.

Restart: Do you feel quiet around now?
