Damaged fan: The computer fan may malfunction due to prolonged 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.
Remove dust. Generally speaking, a newly purchased fan always makes less noise, but it will become significantly louder after being used for a period of time. In fact, dust is one of the important reasons for the increase in fan noise, because all-pervasive dust can always get into a chassis that is not completely sealed.
There may be several reasons why the computer fan suddenly becomes louder: The temperature is too high: The computer will generate heat when it is running. If the heat dissipation is poor, the temperature will be too high, which will cause the fan to accelerate and make a loud noise. noise.
1. The "buzzing" sound from the power supply has a low frequency and can be determined to be the noise caused by the abnormal operation of the exhaust fan.
2. 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.
3. The reason why the computer is buzzing is that the internal components of the chassis touch the fan. The sound is caused by the vibration produced inside the hard disk or optical drive during operation. The fans of the chassis, power supply, processor, graphics card or other accessories produce vibration and sound.
4. The reasons why the notebook fan keeps buzzing are: excessive dust, aging fan, overload operation, improper placement of the computer, and hardware failure. Excessive Dust When a laptop is in use, it will continuously inhale dust and impurities in the air. These dust and impurities will adhere to the fan and radiator, affecting the cooling effect of the computer.
5. The reason is that if the computer is used for a long time, a lot of dust will accumulate on the CPU cooling fan and the power supply fan, which will hinder the normal rotation of the fan and produce noise.
6. Why is the laptop buzzing? Why is the laptop buzzing? Reason 1: After the computer is used for a long time, a large amount of dust will accumulate on the fan blades, causing the fan to The load becomes larger and the speed is reduced. In order to achieve the standard air supply volume, the fan will rotate at a higher speed, causing the fan to be abnormal.
1. 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.
2. The computer fan suddenly becomes louder for the following reasons: Too high temperature: The computer will generate heat when it is running. If the heat dissipation is poor, the temperature will be too high, which will cause the fan to accelerate and generate Loud noise.
3. Under normal circumstances, the higher the cooling fan speed, 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.
1. Solution: Turn on the computer host, and then put a few drops of oil on the rotating shaft of the computer fan to solve the problem. The problem with the loud fan is gone.
2. Open the chassis to make a panel, remove the power supply, remove the front panel of the chassis, and use a vacuum cleaner to suck away the dust inside the front panel, power supply, CPU radiator, and graphics card fan.
3. This is a computer fan failure caused by dust blockage. We can clean the fan regularly and promptly. Lubricating Bearings Bearings are the most important part of fan rotation. If the shaft is rusty, it may also cause the fan to make a lot of noise. At this time we only need to put a few drops of lubricating oil on its bearings at the beginning.
4. What should I do if the host fan makes too much noise when the computer is turned on? Turn it on regularly, especially in humid seasons. Otherwise, moisture in the chassis will cause a short circuit, and a frequently used computer will not be easily damaged. But if there are no lightning rods around your home, do not turn on your computer during lightning and unplug all power cords.
5. You can also remove the fan for cleaning. It should be noted that the aging of the hard disk will also cause the computer host fan to be loud, because the hard disk will age and make noise after being used for too long.
Just open the host to reinforce it; if there is too much dust on the fan, you can open the chassis and clean out the dust; if Caused by computer viruses and Trojans, just scan and kill them.
If the computer fan is noisy, it is necessary to clean the dust blockage, oil the fan shaft, correct the fan blade eccentricity, replace aging parts, and clean the cable. Clean the dust blockage. The accumulation of dust on the cooling fan is one of the reasons for the loud sound of the computer case fan.
The solution is to turn off the computer, take a closer look and see that no wires are touching the fan. You can determine the approximate location just by listening to it, and rearranging the wires can usually solve the problem.
Cleaning the computer fan: First, shut down the computer and disconnect the power source. Pay attention to safety and make sure the fan is in the correct operating position. Then, use an electronic cleaning product such as a jet can or a small vacuum cleaner to remove any dust and debris from the computer fan. Cleaning the fan may resolve the noise problem.
Solution: Turn on the computer host, and then put a few drops of oil on the rotating shaft of the computer fan to solve the problem of loud fan noise.
The computer fan is too loud. Solution: Dust blockage Dust accumulation on the cooling fan is one of the reasons why the computer case fan is noisy. We can first pry open the top interface of the keyboard, use a screwdriver to remove the screws below it, and then remove the keyboard, optical drive, and hard drive according to this, so that you can see the cooling fan.
1. Fan failure: If the fan of the computer host fails, it may cause the internal temperature of the host to be too high, causing bees. song. You can open the main case to check whether the fan is running properly and clean the dust and dirt on the fan. Hard drive failure: Hard drive failure may also cause the beeping sound.
2. The reason why the computer buzzes is that the internal components of the chassis touch the fan. The sound is caused by the vibration produced inside the hard disk or optical drive during operation. The fans of the chassis, power supply, processor, graphics card or other accessories produce vibration and sound.
3. The main reasons for the loud sound of the computer case fan are as follows. The solutions are as follows: Dust blockage: Once the dust on the cooling fan accumulates a lot, it may cause the computer case fan to make loud sound.
4. The reason for the buzzing sound of the desktop computer mainframe may be caused by poor heat dissipation of some hardware of the mainframe, or the fan may have accumulated dust.
5. If it is determined that the sound is caused by these two fans, the most thorough solution is to directly replace the fans, because the long-term rotation of the fans will cause wear of the internal bearings and motors. After replacing the fans, the computer will No more buzzing sound.
6. When the computer is running normally, the heat dissipation of the motherboard will be serious. In order to reduce the temperature and ensure the smooth operation of the computer, the manufacturer has designed a cooling fan for the computer. The buzzing sound your computer makes when it starts up is the sound made by the fan.
