A problem with a big voice on a mainframe computer

1, the most common situation: The CPU fan dust is too thick, fan bearing aging caused by the computer host sound Big

At present, most CPU radiators are installed with fans to achieve rapid cooling purposes. Computer use of a long time, the CPU cooling fan will accumulate a lot of dust, blocking the normal rotation of the fan, resulting in noise. Just clean up the dust. But sometimes even when the dust on the CPU fan is cleaned up, there is still noise. This is due to the aging or lack of oil dryness of the CPU fan's bearing the gap between the bearings caused by the rotation between the sound of the collision, this situation can drop a few drops of sewing machine oil to the fan bearing inside, if it is not possible to replace the fan, the CPU fan price generally in 15 to 50 yuan.

　2, the Power fan has dust or aging caused by the computer host sound big

The power supply is also equipped with fan cooling, so the time will accumulate dust or aging. Because the power supply fan is encapsulated in the power supply inside, so cleaning the power supply fan dust more trouble. It is best to use computer repair dedicated hair dryer to blow out the dust, if not, the home of the hair dryer can also be replaced, but can not let the wind temperature overheating, preferably cold wind. Have hands-on friends can also be removed from the power supply fan (rookie do not try) to clean.

　　3, the video card fan has dust or aging caused by the main computer host sound

Most of the graphics card is also equipped with a cooling fan (some of the direct use of the heatsink, no fan) cleaning method Ibid., it is recommended to directly replace the new fan.

　　4, hard disk aging caused by the computer host sound big

Hard disk use time will also be aging and issued a "pimple, pimple" sound, but the sound is not very big. At present, there is no good solution, can only endure, hehe. If you can't stand it, you'll only have to change your new hard drive.

"The host sound is larger when it is turned on, but it is normal to enter the system." "The reasons and solutions:

This situation is usually caused by the video card fan, now a lot of graphics fan speed can be controlled by the software speed, you just boot did not enter the system because the driver has not been loaded, so the fan speed is the default, when the system is controlled by the software, in idle state speed will automatically reduce, so the sound is small. If that's the case, you don't have to worry about it.

If the above is the case and is in the winter, it may be because the temperature is too low, the fan lubricating oil a bit solidified not to turn on, the fan running up, lubricating oil is not so loud.
