Auto cooling fan) The escort for your performance.
related to friction, air flow noise. 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. High quality cooling fans, of course, its 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 larger power cooling 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. Due to the cooling fan to friction collision between high speed rotating shaft and the bearing, so is also a main source of cooling fan noise.
