A solution to the loud noise of computer operation

To build their own mute computer, it is not a very difficult thing, just a few key accessories on a little choice, you can easily achieve.

The noise of the computer comes from these aspects: the power supply fan, the CPU fan, the chassis fan, the noise of the video card fan, the noise of the hard drive and the optical drive, and the resonant sound. 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.

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 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. 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

As a result of hard disk technology, hard disk read and write data, annoying "giggle" has been basically inaudible, but some hard drive rotation is the "hum" sound is also quite considerable. At present, the hard disk manufacturers have introduced some of the concept of mute hard disk, such as the use of "liquid bearing" technology, Seagate hard disk and Samsung V-series hard drives, are a good choice.

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

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".
