What are the main causes of high computer noise?

Reasons:1The reason for excessive computer noise is usually caused by resonance, and if the computer chassis is not made of good material and unreasonable design, it is easy to cause resonance, which causes a lot of noise.

2.Caused by a fan. There are usually three computer fans: power supply fans, CPU fans, and graphics card fans. Power fans are the main source of noise.

Solution:1Eliminate sources of noise.

Remove the fan and add oil to the rotating part of the fan to increase lubrication. Strengthen the fan screws one by one, and the fan should not vibrate when working.

2.Replace the fan.

If the vibration noise of the fan is too loud and cannot be effectively eliminated, it means that the fan blades have been deformed, and the fan should be replaced. Find a noisy fan, gently press and hold the rotating fan with your hand and gradually increase it to stop rotating, this method can effectively determine which fan is producing the noise.

3.Tighten the screws inside the chassis.

Don't underestimate the tightening of the screws, which is probably the most effective way to eliminate noise. Tighten the screws in the chassis one by one. The joint part of the hard disk, optical drive, and other firmware with the chassis is padded with rubber pads and tightened.

4.Clean up the chassis.

The chassis is cleaned with a brush. Remove the data cables that are not used in the chassis, and remove the devices that are not used for many years. For example, many people's optical drives are basically useless now, and you can unplug the power cord.

5.Organize your cables.

Don't underestimate this, small data cables can sometimes emit a loud resonance sound. Straighten out the data cables and fix them.

6.Tighten the chassis screws.

This is particularly important, some cases are deformed due to poor material, resulting in a loose cover, find a rubber pad where the cover is not tight, and then fasten it with screws.

What should I do if the computer's cooling fan keeps making a "roaring" sound?

Lubricate its shaft. Method: Uncover the paper at one end of the hinge, you will see the hinge, add an appropriate amount of sewing machine oil (even cooking oil) to lubricate, which will greatly reduce the noise of the fan.

The sound of the hard disk is loud, the sound of the hard disk is mainly a gurgling sound, the hard disk of bad quality will be louder, and if the hard disk fragments are too much, the workload of the hard disk will be increased and the sound will be louder, and there is a situation that the hard disk has a bad sector, which will also lead to the sound of the hard disk to increase, just scan it, and defragmentation should be done, by the way, BT and other **tool** files will produce a large number of disk fragments, and the solution is to dump the movie that has been ** every time ** is completed, Save to another partition.

The resonance of the computer noise reduction strategy.

The radiator of the computer noise reduction strategy.

Mainly the noise emitted by the fan, you can change the CPU fan, or the graphics card fan, or the power supply fan, the above "oil" method is generally not good, first, the operation is inconvenient; Second, the effect is not good, and it will not take much time to get sick again**; Third, the ** of these fans is not high, and it will be done once and for all if you change one.

Generally, the noise is emitted by the hard disk rotation and the fan, and after a long time, the dust will definitely be loud, and you open the case to clean up the dust.

Some of the noise is emitted by the optical drive, which may be the aging of the optical drive head and its replacement.

CPU fan, power supply fan, graphics card fan, etc., this indicates that you want to clean the computer's hygiene, it may be dust. It's also possible that you want to oil some accessories.

When the computer is used for a long time, the sound will be a little louder, clean up the dust, remove the power fan and CPU fan to clean and oil, so that the sound is much quieter.

The hard drive has been used for a long time, or the CPU (or graphics card or power supply) fan has run out of oil.

It may be caused by the aging of your machine, so you can try to replace it.

How to control noise? This question cannot be generalized and should be analyzed according to your specific situation. Here is a brief introduction to the characteristics of noise for your reference.

According to the mechanical characteristics of the sound source, noise pollution can be divided into: noise caused by gas disturbance, noise caused by solid vibration, noise caused by liquid impact, and electromagnetic noise caused by electromagnetic action. Noise can be divided into the following according to the frequency of the sound

400Hz 1000Hz high frequency noise. According to the properties of time, noise can be divided into: steady-state noise, unsteady noise, undulating noise, intermittent noise and impulse noise.

Traffic noise, the noise generated during the driving of transportation vehicles belongs to traffic noise. It has two characteristics:1 It is very widespread.

Car noise is the main source of urban noise**; The rapid development of air traffic has improved the number of aircraft....

The computer used to be used well, but now the chassis makes a lot of noise, what is the reason?

01 There are several parts of a computer case that can make noise: fans, optical drives, and hard drives. The most common of these is the fan. Laptops are generally CPU fans.

02 There are usually two or three fans in the case, in addition to the CPU fan in the picture above, the other is the power supply fan (the one above Figure 1), and the fan on the discrete graphics card (Figure 2). If you want to know which fan is making the noise, you can press and hold the CPU or graphics card fan with your hand when you turn on the computer, and you can find out.

03 The noise of the fan is generally due to the lack of oil in the bearing, but if it is not serious, you can remove it and drip a few drops of lubricating oil (like the notebook fan in the picture), and if it is serious, you can only replace the fan.

04 If there is a disc in the desktop optical drive and it is not taken out, it will also make noise, generally the kind of high-speed disc reading sound, if the optical drive is damaged and the disc is inside, it will make a harsh noise.

05 If the chassis emits a very fine clucking sound, and intermittently, it is generally the reading sound of the mechanical hard disk, which will appear when the hard disk reads and writes frequently, and the reading sound of the general hard disk is very small, especially the new hard disk can hardly be heard, but there are some especially loud sounds that have been used for a long time. There is no way to fix this situation, and in fact, it will not affect the use.

1. The sound of the computer stabbing and stabbing.

When the hard disk is turned on, there will be a sound of the hard disk reading, which is normal, but if the sound is too loud, it may be that the hard disk is faulty, if the hard disk is subjected to a large collision or often forcibly shut down, and the power is suddenly cut off during operation, etc., it will cause the hard disk to be damaged and make a sound, in this case, it is recommended to find a professional to check and repair, or directly replace it with a solid state drive.

2. Computer "card card card" or"Buzz"The ringing sound.

This is the sound of the host radiator or the host power supply, open the chassis to check whether the radiator is loose, the dust is too thick and the speed is low, it may be caused by the solidification of the lubricating oil of the fan motor or the absence of lubricating oil, add lubricating oil to the fan, it is best to change to a new radiator. If the power supply fan is too noisy, there is an accessory that you can change to a power supply fan by yourself, or change to a new power supply.

3. CPU alarm tone.

When the CPU temperature is too high, it will alarm, the CPU temperature is too high, mainly check the heat dissipation of the radiator and the chassis, turn on to check whether the CPU fan is not rotating smoothly, and the wind is not enough to replace the good radiator. This sound is emitted by the small speaker linked to the motherboard, and some hosts can unplug the small speaker.

4. The long sound of the computer's tick.

This sound is a memory issue. Generally, the blue screen or boot computer will not be displayed, pull up the memory and reinsert it with the eraser gold finger part, and clean up the memory slot when necessary, you can solve the drip sound.

5. The noise of the computer host caused by dust.

First observe the internal situation of the computer host, whether there is dust stuck in the fan, and use a brush or blower to clean the dust inside the computer and the dust in the hardware fan.

There are several reasons why a computer is noisy and there are several reasons why:

1.Heatsink problem: The heatsink is responsible for dissipating the heat generated when the computer is running, and if the heatsink accumulates dust or the fan does not rotate properly, it will cause the computer to become noisy. At this point, the radiator should be cleaned or replaced with a new one.

2.Chassis problem: The chassis is the space where the parts in the computer are placed, if the chassis structure is not reasonable or the material is not good, vibration or resonance will produce sound. In this case, you can change to a better quality chassis or buffer treatment.

3.Hard disk problem: The hard disk is one of the most noisy parts of the computer, and if the hard disk is old or damaged, it will make a lot of noise. At this point, you should back up your data and replace it with a new hard drive.

4.Power supply problem: The power supply is the part that supplies power to the computer, and if the power supply is not of good quality or is aged, it will produce noise. At this point, a high-quality power supply should be replaced.

5.Other problems: In addition to the above reasons, the computer may also be noisy due to the abnormal operation of some parts and resonant sounds, which requires further inspection of the computer and corresponding treatment.

To sum up, the high noise of computers is caused by a combination of factors, and the specific reasons need to be considered comprehensively. In general, regular cleaning, checking whether computer parts are running properly, replacing aging parts and other measures can effectively reduce computer noise.
