The sound of the fan inside the chassis is getting louder and louder; the reason is that the fan of the graphics card is lack of oil due to the bearing; the bearing hole is worn out - the gap between the shaft of the fan and the bearing is too large; and the axial active clearance of the fan is too large; The fan blade can move a few millimeters back and forth. The fan moves axially after the transition; and the plane of the blade's transition is also swaying; not only the wear is getting more and more aggravated; together, a lot of noise is generated. Most of the fan problems are Because of this, although the replacement of a new fan is the most energy-saving; but it does not meet DIY energy; secondly, it is not always possible to find a type that can be replaced. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Of course, this kind of faulty fan is not uncorrectable; I will analyze a repair method now. The information is very simple; just a small piece of cans of aluminum and a little butter (the butter should be clean and free of impurities).
1. First clean the dust on the fan; prevent dust from entering the bearing during the installation process.
2. Remove the self-adhesive seal of the bearing seal; remove the bayonet on the shaft,
3. Clean the residual oil in the bearing with a clean tissue or a soft cloth; then wipe the shaft clean.
4. Take a little bit of butter in the bearing; the principle is to avoid more serious effects on the speed.
5. Then cut the aluminum skin of the can, cut the outer diameter of the bearing pin, and cut a small piece; and dig a small hole in the center that can just pass through the shaft; pad it between the bearing and the bayonet; reduce the bearing The interval between axial movement and parallel movement. If the gap is large; it is necessary to put a few thickening on the pad; so that the front and rear movement of the bearing is less than 0. 5mm.
6. Seal the oil seal; add a bit of butter; finally put the fan back and tighten all the screws and nuts that you want to replace.
Try to connect the power supply; you will find that the sound is much smaller; and this can be used for at least 2 years. However, the demand is prompted; although the sound is smaller; but because the precision of the craft is limited; the speed will be slightly reduced.
