Cooling fans are classified according to their bearings. They are mainly oil-impregnated bearings and double-ball bearings. However, it seems that oil-impregnated cooling fans are more prone to noise problems. Why?
The material of oil-impregnated bearings is poor, the process is rough, and the precision is poor. This is the reason that the oil-impregnated bearing type cooling fan is prone to produce noise for a long time. The sound is very good at the beginning because there is lubricating grease between the bearing and the shaft core, which slows down The direct friction between the shaft core and the bearing is eliminated. But as time goes by, the lubricating oil will dry out, and when it is gone, the sound will become louder and louder.
The precision of the double ball bearing is very high. It is made of steel. From the beginning, what kind of sound will be the same after one or two years. This is also a product that has been used for a long time and has high requirements for noise. The reason for the double ball bearing fan instead of the oil-bearing cooling fan.
