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?
Oil-impregnated bearings have poor materials, rough craftsmanship, and poor precision. This is the reason that long-term use of oil-impregnated cooling fans is prone to produce noise. The sound is very good at the beginning because there is lubricating grease between the bearing and the shaft, 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 one or two years later. 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.
Will the power cord of the cooling fan burn if it is connected upside down?
