How to make noise lower?
The use of ball bearings to reduce the noise of cooling fans, fans using bearings with oil, roller bearings, oil bearings in the early in the case of sufficient grease low noise, with the longer the use of grease evaporation, increase the gap between the stator and the rotor to produce more vibration and noise with a large, so the use of ball bearings will be better
