Teach you how to reduce the noise of the chassis

If the chassis noise is big, it will affect the mood, whether in learning or in the game. So what happens when the chassis is noisy? How do I reduce the noise of the chassis? Here's a look at the case for a little bit of noise reduction.

The source, the noise I produced

The noise generated by the computer is caused by the resonance of the chassis, and the main culprits are:

1. Hard disk, optical drive internal mechanical part of the work produced by vibration;

2. The cooling fan of the chassis, power supply, CPU, video card and other accessories rotates, resulting in vibration and sound.

As you can see, the biggest impact is the cooling system, as long as there is a fan rotation will produce sound. However, these cooling equipment is necessary, can not be removed, only from the reduction of noise generated by the fan to start. Of course, noise reduction is necessary, because in addition to reducing annoying sound, but also to a certain extent to extend the fan, hard disk and other accessories of the service life.

Chassis noise one of the major solutions: shock absorption, for the chassis noise reduction

For the chassis, it itself is the most quiet of many accessories, but because of the installation of other accessories and thus become the distribution of all noise. For example, in 5.25-inch and 3.5-inch positions, the hard drive and the optical drive will vibrate at work, and the side panels, front and rear panels will also resonate because of the fan rotation. The easiest way to solve these resonances is to tighten their mounting screws.

If there is still a larger noise, you can contact the chassis parts of the installation of damping pads, shock absorbers and so on. can also be a sound-absorbing cotton in the chassis, so that the voice inside the case is absorbed by the absorption of cotton, will not produce refraction, thus reducing the noise to the minimum, usually 6cm thick sound-absorbing cotton can reduce 10~15 decibel volume. 3M sound-absorbing cotton was once used in car internal noise reduction, so the mute effect is very good. In the pavement sound-absorbing cotton, the need to be based on the size of the inside of the chassis to cut, attention, must not block the cooling hole.

Damping nails can be used instead of screws to reduce noise

On the chassis panel, the sound-absorbing cotton should be left out of the cooling hole

Some users are afraid of the computer too hot, they installed in the chassis more than 8cm fans, the result of the temperature not only did not drop how much, but noisy to unbearable. This is because the fan instead of disturbing the internal air duct inside the chassis, affecting the heat dissipation. In fact, you only need to install a lower speed and quiet 12cm fan on the front panel, it's high heat dissipation efficiency, can reduce the number of fans, thereby improving the chassis noise problem.

Large Chassis Noise Solution II: Dust, for the power to reduce noise

The inlet of the power supply is also the most easy to invade the dust, especially the installation of the power supply, it directly from the bottom of the chassis into the wind, its easy to absorb the trouble of ash can be imagined. When the fan blades and bearing on the accumulation of more dust, it will affect the rotation, resulting in no small noise. So be regular for the power supply clean, you can use a vacuum cleaner to clean up the dust. If the power over the warranty period, you can also open the power supply for the fan bearing dust, oil, this can also significantly reduce noise.

To completely dust the fan, only turn on the power sweep

can also be added to the power supply damping pad. Because of the power supply and contact the size of the chassis larger, you can cut the damping pad out of a side length of 4cm rectangular small block, affixed with double-sided adhesive, placed in the bottom of the power supply bracket, so as to avoid the power supply fan rotation caused by the chassis resonance noise.

Adding a damping pad to the power supply bracket is an obvious result.

Chassis noise Solution of the three: cooling, for the CPU, video card noise reduction

CPU, graphics card is the key parts of the computer, the matching radiator is also more important, so they have become one of the sources of noise. Take the graphics card, the current market in high-end graphics cards are mostly paired with the fans have intelligent temperature control function, when the GPU temperature increases, the fan speed will increase, the resulting noise will increase.

The best way is to strengthen the heat sink cooling capacity, so that the fan in a low speed state. For example, the silicone grease at the contact point of the processor, graphics card, and radiator will harden or degrade for a long time, resulting in lower heat conduction efficiency and high fan speed, so you can periodically scrape the hardened old silicone grease, and then evenly coated with new silicone grease, can also be used to heat conduction more efficient gray silicone grease.

Grease on the CPU needs to be evenly formed

Of course, can also be replaced with better cooling performance of the mute radiator, such as a pure copper heat pipe, aluminum alloy fin area, large fan size, support temperature of the radiator, generally use large brand products on the right. @ Duan Xiao Book

Editorial point of view

@ Computer Newspaper Lu Yuan: Many users think that the noise of the chassis, its internal cooling effect is the better, in fact, this is not directly related to, you think if the use of the inferior fan, in its roar, will not get any good cooling effect. Therefore, in addition to the use of more muted heat sink, but also need to solve the problem of noise from the source, sometimes only need to do a little bit of improvement can also make your chassis become quiet.
