Hello everyone, Lin Fei to answer the above questions for you, the chassis sound is buzzing, the chassis sound is loud, many people do not know, now let's take a look!

Computers are so familiar to us that we come into contact with them every day. In particular, white-collar friends in the office use computers every day. But we are familiar with the use of computers, and sometimes when we turn on the computer, we will find that the sound made by the mainframe is too loud. It seriously affected our mood. And many friends don't know why the host makes such a loud noise. Others think that the mainframe of the computer is burnt out. In fact, it is not, so next, Bian Shaw will share with you in detail why the mainframe of the computer makes so much noise.

What is the reason why the computer is so loud?

1. The fan touches inside the chassis.

two。 Vibration caused by internal mechanical parts of hard disk and optical drive

3. Vibration and sound caused by the rotation of the cooling fan of chassis, power supply, CPU, graphics card and other accessories.

As you can see, the greatest impact is the heat dissipation system, as long as the fan rotates, it will produce sound. But these cooling devices are necessary and cannot be dismantled. We can only start by reducing the noise generated by the fan. Of course, noise reduction is necessary, because in addition to reducing annoying sounds, it can also extend the service life of fans, hard drives and other accessories to a certain extent.

Ways to solve the problem of loud chassis noise:

First, comb the internal wires.

Finally, it is added that sometimes the data cable and power cable of the hard drive will make a lot of noise when they encounter a CPU fan or a video card fan. The solution is to tidy up the wires that come into contact with the fan and try not to touch the fan.

Second, reduce the temperature to reduce the noise of CPU and graphics card.

CPU and graphics card are the key accessories of the computer, and the matching radiator is also very important, so it has become one of the sources of noise. As far as graphics cards are concerned, most of the high-end graphics cards on the market are equipped with fans with intelligent temperature control functions. When the GPU temperature increases, the fan speed will also increase, and the noise will also increase.

Silicone grease on CPU needs to be evenly smooth.

Of course, it can also be replaced with a mute radiator with better heat dissipation performance, such as more pure copper heat pipes, larger aluminum alloy fins, larger fan diameter and better temperature control. Generally speaking, it is right to use products of big brands.

Third, dust removal and noise reduction for the power supply.

A damping pad can also be added to the power supply. Due to the installation position of the power supply and the large contact area with the chassis, a rectangular piece with a side length of 4cm can be cut off from the damping pad, affixed with double-sided glue, and placed on the bracket at the bottom of the power supply, so as to avoid the chassis resonance noise caused by the rotation of the power supply fan.

The reason why the chassis has been buzzing all the time and its solution.

The effect of adding damping pad to the power support is obvious.

Fourth, reduce the shock and noise of the chassis.

As far as the chassis is concerned, it is the quietest of the many accessories, but because of the installation of other accessories, it becomes a distribution center for all the noise. For example, in the 5.25-inch and 3.5-inch positions, resonance will occur when working because of the vibration of the hard disk and the optical drive, while the side panels, front and back panels and other parts will also resonate because of the rotation of the fan. The easiest way to solve these resonances is to tighten their mounting screws.

If there is still a lot of noise, you can add damping pads, damping nails and so on. Parts that come into contact with the chassis. Sound-absorbing cotton can also be laid in the chassis, so that the sound in the chassis is absorbed by sound-absorbing cotton without refraction, thus reducing the noise to a minimum. Usually 6cm thick sound-absorbing cotton can reduce the volume by 10 to 15 decibels. 3M sound absorbing cotton has been used to reduce the noise of cars, so the mute effect is very good. When laying sound-absorbing cotton, it needs to be cut according to the internal size of the specific box. Be careful not to clog the cooling hole.

The air inlet of the power supply is also the most vulnerable place for dust to invade, especially the power supply installed under it. It enters the air directly from the bottom of the chassis, and the trouble of easily absorbing dust can be imagined. When the wind blades and bearings accumulate more dust, it will affect the rotation, resulting in a lot of noise. So to clean the power supply regularly, you can use a vacuum cleaner to clean the dust. If the power supply is out of warranty, you can also turn on the power supply to remove dust and oil the fan bearings, which can also significantly reduce noise.

The best way is to strengthen the heat dissipation capacity of the radiator and keep the fan running at a low speed. For example, the silicone grease at the contact of the processor, graphics card and radiator will harden or deteriorate over a long period of time, resulting in a decrease in thermal conductivity and high fan speed. Therefore, the hardened old silicone grease can be scraped off regularly and then evenly coated with new silicone grease, or replaced with gray silicone grease with better thermal conductivity.

These are the reasons we share with you about the noise of the mainframe computer. I also hope that when you turn on the computer in the future, if you encounter such a loud noise from the host computer, you can find out the cause of the noise from the host computer according to the content we share, check it according to the way we share it, and fix it in time. At the same time, we also suggest that we should learn how to clean the computer at ordinary times. Clean the computer regularly so that there will be no loud noise from the mainframe.

At the end of this article, I hope it will be helpful to you.
