What is the reason for the loud noise of computer host?

Many friends have encountered computer noise problem, let's talk about the computer noise is the reason. Generally speaking, the computer produces the noise mainly has the following several possibilities.

　　How to solve the computer noise?

The noise of the computer comes from these aspects: the power supply fan, the CPU fan, the chassis fan, the video card, the noise of the power supply fan, the noise of the hard disk and the optical drive, and the sound of the chassis resonance. We hear the computer running "hum" sound, is the superposition of these sounds, to effectively reduce computer noise, the use of a separate mute power supply or mute CPU fan, often does not achieve good results, need to start from each source of noise to solve the problem.

For some old computer noise is large, mostly due to the old fan or ash too much, the solution is to clean up the dust or replace the cooling fan. This article mainly introduces the new computer noise how to solve, here will not involve dust and other interference, mainly from the fan speed and so on to solve.

　　How to solve the noise of new computer?

　　1, the fan noise elimination

The power supply fan and the CPU fan noise are the main sources of noise. The problem of the power supply fan noise is easier to solve, directly buy a mute power supply on it.

Power noise

Power supply fan noise reduction is generally to reduce fan speed, and CPU fan if the speed reduction, it is bound to affect the CPU cooling, so the CPU noise reduction method is mainly in the lubrication of bearings and fan-leaf structure design.

CPU Noise

Due to the high speed of the CPU fan, so that the CPU fan noise value to achieve the level of mute power is still a bit difficult, but we still try to choose a mute function of the fan. Of course, it is also a good idea to add lubricating oil to the fan bearing.

The video card fans and chassis fans have a relatively small amount of noise, but too many chassis fans are installed in the chassis, which can also increase computer noise. Installing fewer fans is an effective way to reduce noise, but for computers that must have multiple chassis fans, you can choose some large-diameter, low-speed chassis fans.

　　2, hard disk or CD-ROM noise reduction

The noise generated by the hard disk can be divided into resonant noise and read and write noise, we can use pad to reduce the hard drive very host of the resonant noise, the hard disk defragmentation has been achieved to reduce the effect of read and write noise, of course, there are other ways to reduce resonance and read and write noise

The noise of the optical drive is often difficult to solve, some optical drive noise even reached an alarming point, with some friends said, read the CD when "like a helicopter." Some friends installed like DVD-ROM utilities software, in the use of optical drive, mainly to watch the DVD, effectively reduce the optical drive noise.

　3, the elimination of resonant noise

Reduce chassis Noise: if we look carefully we will find that a lot of noise comes from inside the chassis, so it is imperative to reduce the chassis noise.　　We can reduce the chassis noise by bundling the inside of the chassis, enclosing the chassis, and adding a sound-absorbing device. Not every computer will produce resonant noise, the elimination of resonant noise is actually very simple, adjust the placement of the chassis or add some soft cushion on it. Increasing the sound-absorbing cotton inside the chassis is not a good method, which often affects the cooling of the chassis.

The above is only commonly used method, in fact, we move a little more brain, the noise problem is not on the "problem"
