"Waterproof Cooling Fan" fan speed and power are inextricably linked, directly affects the speed of the size of the fan power size. Usually within a certain range, the fan speed is higher, it is transferred to the air intake, the greater the amount of CPU, CPU cooling effect obtained will be better. But if the speed is too high, "Waterproof Cooling Fan" may produce a lot of noise at high speed during a long time may also be shortened fan life. Therefore, when we select the fan speed, CPU heat should be based on a decision, the best choice in the 3500 Speed Go "Waterproof Cooling Fan" 5200 transferred between.
