Ghost win7 system desktop fan sound loud and big solution

When our computer has been used for a long time, we will encounter some problems, such as users who use desktop computers report that the computer is booting The fan sound of the computer will be too loud, and the heat dissipation effect is very bad. As the most important tool fan for computer cooling, and because the frequency of use is high, the noise is getting bigger and bigger. How to solve this fault? Let's share with you the specific steps of the Ghost win7 system desktop computer fan sound.

big computer fan noise causes and solutions:

1, the blade is loose

When the loose blades when the blades bearing on the loose As the bearing wears, the gap becomes larger. The fan can be removed and checked, and the screw is tightened to prevent re-vibration.

2, bearing lack of lubricating oil

Bearing plays a major role in fan transfer. When the user's computer has been used for a long time, when the bearing lacks lubricating oil, it rotates at high speed during computer use. When there is noise, it is necessary to drop a few drops of lubricating oil on the fan bearing. If there is no lubricating oil, you can use the sewing machine oil instead, but do not use edible oil instead, because the edible oil particles are large, the bearing will be Injury.

3, it is recommended that users develop regular cleaning of the power box and the pile of dust on the circuit board.

4, fan quality problems, eccentricity

If the user's cooling fan is of poor quality, due to technical defects, the center of gravity of the fan blade may not be on the axis, Forming "eccentricity" 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. Then use a thin wire to hang it in its center position. After it is still, look at which side it sinks. Gently grind the sinking end on the grinding wheel a few times, and then test it until the fan can be in the horizontal position. And then install it on it.

Specific repair method:

1. Clean the dust of the fan to avoid dust entering the bearing during the installation process.

2. Seal the bearing Remove the self-adhesive tape and remove the pin on the shaft.

3. Wipe off the residual oil in the bearing with a tissue or a soft cloth, and wipe the shaft at the same time.

4, add a little butter to the bearing lubrication;

5, then cut the aluminum can of the can pull the same as the outer diameter of the bearing pin, cut a round piece, and dig a hole in the middle just to pass through the shaft The small hole of the rod is placed between the bearing and the bayonet to reduce the distance between the axial movement of the bearing and the parallel movement. If the gap is large, it is necessary to put a few thicknesses on the cushion to make the bearing front and rear. The moving distance is below 0.5mm;

6. Seal the oil seal, add a little butter to lubricate, and finally put the fan back.

About the perfect solution to the Ghost win7 system desktop fan sound is a big way to share with you here, if you also found that the desktop fan you use is too loud, you can pass the above method I have solved it and hope to help everyone.
