Why is the computer exhaust fan so loud?

Why is the computer exhaust fan so loud?

1. Fan damage: The computer fan may malfunction due to long-term use or other reasons. If your computer fan's blades, bearings, or motor are damaged, it may become unusually loud. At this time, it is recommended to replace the computer fan.

2. Vibration noise is also an important component of fan noise. Because the blades are loose on the bearings and the bearing wear causes the gap to become larger, etc., so you only need to remove the fan and tighten the screws. Once it's firmly fixed, it won't vibrate anymore.

3. Dust clogging: Once the dust on the cooling fan accumulates, it may cause the computer case fan to make loud noise. Use a vacuum cleaner to suck up the dust on the panel, power supply, radiator, etc., then use a rag with some alcohol to wipe the inside of the case clean, put it in the vent to dry, and then put the computer back.

4. It may be that the exhaust fan has accumulated too much dust or the fixing screws are loose, causing the position to shift. In this case, the notebook exhaust fan may also sound too loud. It may also be a problem with the power supply. The power supply is too high. If it is too large or too small, it will cause problems. The computer needs to be stably powered according to the voltage required by the power supply.

5. Reason 1: There are many reasons for the loud noise of the fan, and we need to eliminate them step by step. Let’s exclude it from the software first.

6. Most of the computer exhaust fan noise is caused by hardware or software. In terms of hardware, it may be caused by a lot of dust or debris in the exhaust fan, or problems with the exhaust fan's shaft or balls. In terms of software, if the CPU occupancy rate is high and overheating, the fan speed will increase, causing the fan sound to be loud.

Why is the laptop exhaust fan so loud?

1. The fan is loud. If the machine has been on for two years, it means the fan is dusty. If the new machine is not working, the machine generates a lot of heat. The sound of the fan rotating with the temperature of the machine should be the sound of the hard disk. The fan heat sink is blocked by dust or there is too much sludge inside the fan shaft, causing the fan performance to decrease.

2. It may be because the CPU temperature is too high, the fan has too much dust, or the fan has aged. The CPU temperature is too high. Solution: It is natural for the CPU temperature to be too high and can be solved by reducing the number of open program windows.

3. Reason 2: The cooling fan is damaged. The fan will gradually wear out after long-term use, or the bearing is short of oil, which will cause the fan to make a loud noise when rotating.

4. After being used for too long, the fan coil is aging and lacks oil. Due to improper use, impact or vibration, the bottom bracket may be bent. The fan has excessive dust accumulation or loose fixing screws, causing the fan to shift position. Power supply problem.

5. The rotation of the fan is related to the temperature of the CPU. If the ambient temperature is high, running too many programs or large software will cause the CPU temperature to rise. When the CPU temperature increases, the fan will rotate more frequently. , the sound will be louder.

6. After being used for too long, the fan coil is aging and lacks oil. Due to improper use, impact or vibration, the bottom bracket may be bent. The fan has excessive dust accumulation or loose fixing screws, causing the fan to shift position. Power supply problem. Solution: Usually the computer fan speed is not fixed.

Why is the fan of the computer main case very loud? How to solve it

The reason why the desktop computer main case is buzzing may be caused by poor heat dissipation of some hardware of the host, or the fan has a lot of dust. .

One of the causes of noise is that the computer fan hits the cable. We can first open the computer case, carefully check its cables, rearrange the computer fan when the cables are encountered, and then put the computer back together.

The computer chassis fan is very loud because there is a problem with the CPU fan setting in the bios. The specific solution is as follows: First, when the computer is turned on, press the hotkey on the keyboard to enter the bios and find the option . Then select.

The rotation of the fan is related to the temperature of the CPU. If the ambient temperature is high, running too many programs or large software will cause the CPU temperature to rise. When the CPU temperature increases, the fan will rotate more frequently and the sound will be heard. It will also be bigger.

The sound coming from the main computer case should be mechanical. You can first check the operation of each cooling fan. Observe the mechanical sound of the fan. Then, deal with the problem cooling fan. You can also use shock-absorbing glue and paste it on the chassis sealing plate to achieve shock-absorbing and noise-reducing effects. The fan in the host is aging.

Why does the fan of the computer host suddenly make a loud sound

1. Under normal circumstances, the higher the speed of the cooling fan, the louder the noise will be. The reasons for the louder sound of the cooling fan are as follows: the weather is overheated, the internal temperature of the chassis continues to be high, and the heat cannot be dissipated in time, causing the cooling fan to continue to run at a high speed, resulting in louder noise.

2. Solution: The bearings and blades of the CPU fan are the places that are most likely to cause noise. After long-term use, the bearings of the fan may have too much friction due to lack of oil, resulting in hair loss.

3. When the fan is turned on, the fan runs at full speed, so the sound will be loud. However, during normal operation, the speed will slow down and the sound will be soft. Because today's motherboards are automatically controlled by the BIOS and automatically adjust the fan speed according to the temperature.

4. What should I do if the computer fan makes a loud sound? In winter, the ambient temperature is low. Generally, the power supply fan makes a loud sound when starting up, and the sound gradually decreases after preheating. The CPU fan is less affected inside the case. In addition, outdoor people's activities decrease in winter, and external noise decreases. It feels like the chassis noise increases.

5. The sound of the computer host is loud. If the sound is loud when the computer is busy, such as downloading or watching movies, or playing large games, and the sound is not loud at first but suddenly becomes louder, this can be judged to be the CPU fan. Or a problem with the graphics card fan.

How to solve the problem of loud computer exhaust fan

1. Clean the dust inside the computer, especially the fan parts, to make the fan rotate more smoothly.
