The Elimination Of Fan Noise Is Mainly Caused By Power Fan And CPU Fan Noise.

The issue of power fan noise is relatively easy to solve, just purchase a silent power supply.
The method of noise reduction for power fans is generally to reduce the fan speed, and if the CPU fan speed is reduced, it will inevitably affect the heat dissipation of the CPU. Therefore, the main method of noise reduction for CPUs still lies in the lubrication of bearings and the structural design of fan blades.
Due to the high speed of the CPU fan, it is still a bit difficult to achieve the noise level of a silent power supply, but we still try to choose a fan with a silent function. Of course, adding some lubricating oil to the fan bearings yourself is also a good way.
The noise generated by graphics card fans and chassis fans is relatively small, but installing too many chassis fans inside the chassis can also increase computer noise. Installing as few fans as possible is an effective way to reduce noise, but for computers that must have multiple chassis fans installed, it is possible to choose some large diameter and low speed chassis fans.
