Sometimes when using the computer, you may hear the buzzing sound from the computer. I believe many users have encountered it, especially those computers that are older or have not been cleaned for a long time, the noise is especially loud, sometimes This kind of noise has seriously affected our use, so how should the computer noise be solved?
1. The fan blades of the fan are "eccentric"
If the quality of the fan is not good, the center of gravity of the fan blade does not cause "eccentricity" on the shaft center. After such a fan rotates, the fan bearing gradually wears out, making the vibration aggravated and the noise louder.
Solution: It is recommended to replace a high-quality fan.
2. The cpu fan bearing is short of oil
The sliding bearing fan has been used for a long time, and the lubricating oil inside has dried up.
Solution: Add some oil to the fan.
3. The speed of the fan is high
The reason why the new fan is loud is often caused by the high speed of the fan, especially the original fan. If the temperature of the processor is not too high, it is necessary to increase the speed of the fan of the radiator.
Solution: The first method is to replace the large fan blades, use a large heat dissipation fin area, and use a radiator with better thermal conductivity metal, so that the speed of the fan will be very low, and the noise will be very small. The second is to manually adjust the speed of the processor fan to a fixed speed with low noise.
4. Too much dust accumulates
If the CPU fan has been used for a long time, a lot of dust will accumulate on the fan blades. If it is in a dusty and humid environment, a layer of mud-like dirt will form on the fan.
Solution: It is also the same as oiling the fan, first remove the fan, the specific disassembly method is as above, and then use a small mini vacuum cleaner or hair dryer to clean the dust, be careful not to get water.
