The perfect solution to the Ghost win7 system desktop computer fan sound method

computer fan loud sound causes and solutions:
1, the blade appears loose
when the fan blade is loose, the blade is on the bearing Looseness and wear of the bearing cause the gap to become larger. The fan can be removed and checked, and the screw is tightened to prevent re-vibration.
2, bearing lack of lubricating oil
Bearings play a major role in fan transport, when the user's computer has been used for a long time, when the bearing lacks lubricating oil, it will generate noise when the computer is used at high speed. Therefore, it is necessary to drop a few drops of lubricating oil on the fan bearing. If there is no lubricating oil, you can also use the sewing machine oil instead, but do not use cooking oil instead, because the edible oil particles are large, it will cause damage to the bearing.
3, it is recommended that users develop regular cleaning of the power box and the pile of dust on the circuit board.
4, the quality of the fan, eccentricity phenomenon
If the quality of the cooling fan used by the user is poor, due to the defects in the process, the center of gravity of the fan blade may not be on the axis, forming "eccentric" Phenomenon, when used for a long time, the fan's "eccentricity" phenomenon will become more and more serious, which will not only generate noise, but also damage the CPU. Solution: Remove the fan and then hang it with a thin wire. Its center position, after it is still, see which side it sinks down, lightly grind the sinking end on the grinding wheel a few times, and then test it until the fan can be in the horizontal position, then install it That's it.
Specific repair method:
1, clean the dust of the fan to avoid dust entering the bearing during the installation process;
2, tear off the adhesive on the bearing, and put it on the shaft Remove the pin;
3, wipe the residual oil in the bearing with cotton paper or soft cloth, and wipe the shaft clean;
4, add a little butter lubrication in the bearing;
5 Then, cut the aluminum skin of the can to cut a round piece as the outer diameter of the bearing pin, and dig a small hole in the middle that can pass through the shaft, and pad it between the bearing and the bayonet to reduce The distance between the axial movement of the bearing and the parallel movement. If the clearance is large, it is necessary to put a few thicknesses on the cushion, so that the forward and backward movement distance of the bearing is less than 0.5mm;
6, the oil seal is sealed, plus Lubricate the butter and finally replace the fan.
