Hello everyone, Lin Fei to answer the above questions, chassis noise how many decibels is normal, chassis noise many people do not know, now let's take a look!

1. First of all, let's talk about where the noise from the mainframe comes from. The main components of the host include: processor, memory, graphics card (ignored by integrated video card), motherboard, hard disk, power supply and other computer hardware. Noise-prone accessories are: processors (mainly cooling fans), graphics cards (mainly independent graphics cards), hard drives and finally memory. In fact, this memory noise is relatively small, even if it occurs, it is accompanied by computer failure, so strictly speaking, memory can be excluded.

2. knowing the main noise sources of the mainframe, we need to find the source of the noise of the mainframe. If the host computer makes a lot of noise, first open the computer chassis, and then open the computer, carefully observe and listen to the source of the noise.

3. One: if it's just buzzing, it's probably the sound of the fan. Because the fan has been used for a long time, the interior is dry and so on. Naturally, there will be some small buzzing, which is a normal phenomenon. If you need to solve this problem, you can remove the CPU fan, thoroughly clean up the dust, and add some fan oil and so on, the effect is immediate.

4. II: obvious clicking sound

5. There is an obvious clicking sound, which is often caused by the power cord or CPU fan power cord and hard disk fan cable touching the CPU fan or graphics card cooling fan.

6. Solution: turn off the computer and take a closer look, no cable touches the fan. When you listen, you can judge the approximate position just now, which can usually be solved by rearranging your lines.

7. 3: the noise location comes from the hard drive.

8. The disk damage inside the hard disk is also easy to produce noise, mainly due to the noise caused by the friction between the magnetic head and the hard disk. When this happens, the noise is generally more obvious, and you will feel a strong shock when you touch the hard disk by hand. This situation indicates that the hard drive is about to be damaged. At this time, it is recommended that you make a good data backup, replace the hard drive, and solve the noise and data security problems.

Nine, four. Noise source power supply

10. The power supply is also a noise-prone accessory. The noise usually comes from power supplies, cooling fans and the internal circuits of the computer. The most common source of noise is the power supply cooling fan. We can easily judge this part through our own observation and listening. Solution 3360 if the power supply is under warranty, it is recommended to have it under warranty. In addition, for the old power supply whose warranty period has expired, you can try to clean the dust yourself. In addition, a small problem with the internal circuit of the power supply can also produce all kinds of strange noise. For example, a failure of an internal transformer is likely to produce harsh and indescribable noise. It is recommended to replace the power supply or repair.

11. The above are the causes and solutions of computer noise. Some stand-alone video cards may also produce noise. We should judge and solve it in accordance with the above method. I won't repeat it here. I believe you already have a general understanding of the noise of the mainframe.

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