the cooling fan, air flow and friction. Fan speed is higher, the air volume, the greater the noise caused by the will, the greater the other factors of the vibration of the fan itself is also cannot be ignored. Of course the high quality of fan vibration will be small, but the two in front of the person is difficult to overcome. To solve this problem, we can try to use the size bigger fan. Should be under the condition of the same volume, big fan work at low speed when the noise is smaller than small fan noise at high speed work. Another we easy to overlook the factor is the fan bearing. Because of the high-speed fan rotates to the friction between shaft and bearing collision, so is also a main source of cooling fan noise.
