Why is my new desktop computer case so noisy?

Are you troubled by the loud noise of your new desktop computer case? PHP editor Xigua provides you with an in-depth analysis of the causes of excessive chassis noise, and provides you with comprehensive solutions from hardware configuration to cooling system. Continue reading this article to learn how to effectively reduce chassis noise and create a quiet and comfortable computer experience.

1. Why is the new desktop computer case so noisy?

1. The chassis sound mainly comes from the CPU fan, graphics card fan, power supply fan, hard drive and chassis fan.

The method of detection and troubleshooting is to open the side panel of the chassis and carefully identify the source of the noise. The CPU fan is original and the general noise is about 20DB. It is difficult to hear anything.

The graphics card fan is different, because the radius is small, the rotation speed is naturally high, and the noise is generally loud.

As for the power supply, large-sized fans are now used. Generally, there is no big noise problem, but if there is a problem with the fan, the sound will be loud.

2. A high-end computer will generate a lot more heat. If there are more cooling fans, the noise will be louder. But generally the 3 fans are not very noisy, maybe they are running at full speed. Download the Chinese version of SpeedFan, adjust the speed of each fan, and the noise may be reduced. But make sure the heat dissipation is normal.

2. Is the chassis noisy?

　1. If it’s just a buzzing sound. Most of the sound is caused by the fan. Due to the fan being used for a long time and the interior being dry, there will naturally be some small buzzing noises. These are normal phenomena. If you need to solve this problem, you can remove the CPU fan, completely clean the dust, and apply some fan lubricant to see the effect immediately.

　2. Obvious clicking noise. If there is an obvious clicking noise, it is often caused by the power cord or the CPU fan power cord and the hard disk fan cord touching the CPU fan or graphics card cooling fan. You can turn off the computer first and take a closer look to see that no wires are touching the fan. You can determine the approximate location just by listening to the problem. Rearranging the wires can usually solve the problem. ​

​ 3. The source of the noise is the hard drive. Damage to the internal disk of the hard disk can also easily produce noise, mainly caused by the friction between the magnetic head and the avoidance. In this case, the noise is usually very obvious. If you touch the hard disk with your hands, you will feel a strong vibration. This situation indicates that the hard disk is already at a point where it is about to be damaged. At this time, it is recommended that you backup your data and replace the hard drive to solve the problem of noise and data security. ​

​ 4. Noise source power supply. Computer power supply is also an accessory that is prone to noise. Generally, noise sources come from the power supply cooling fan and the internal circuit of the computer. The most common source of noise is the power supply cooling fan. We can easily identify this part by observing and listening. Solution: If the power supply is within the warranty period, it is recommended to take it for warranty. In addition, if the warranty has expired for the old power supply, you can try to clean the dust yourself. . In addition, small problems in the internal circuit of the power supply can also produce various weird noises. For example, internal transformer failure can easily produce harsh and indescribable noises. It is recommended to replace the power supply or repair it. ​

3. Is the chassis fan noisy?

1. The layout of the cables in the case is unreasonable. The computer fan touches the cables when rotating, causing the problem of loud noise in the case.

2. The computer fan in the case is not firmly installed, and the fan vibrates when it rotates, causing the case to The sound suddenly becomes louder

3. The chassis fan accumulates dust, and the resistance increases when the fan rotates, causing the computer fan to make a loud sound

4. The last one may also be caused by viruses and Trojans. Now Computer fans are basically automatic temperature-controlled fans. If the computer is infected and the CPU usage is extremely high, causing the CPU to heat up, the computer fan will automatically speed up to reduce the CPU temperature. This situation may also cause the computer chassis to be loud.

(1) Clean dust

After using the computer for a long time, it will absorb a lot of dust. As the fan is a heat dissipation component of a computer, excessive accumulation of dust will not only cause loud noise, but also affect the heat dissipation performance of the computer. At this time, dust cleaning becomes a must.

2) Replace the fan

Maybe the fan has quality problems, the fan is old, or there is a problem with the fan page. If the computer does not dissipate heat well, the fan will spin faster, causing the sound to be very loud. If this happens, the fan must be replaced with a new one. Try to choose a silent fan.

(3) Check the cable layout

Re-arrange the layout inside the computer case, or the fan screws are not firmly installed, just check and reinforce them.

(4), Comprehensive antivirus by Computer Manager
