The heat value determines the rotational speed of the radiator fan

The main performance of the radiator fan is reflected in the following aspects: speed, blade shape, blade Angle and bearing system. Under normal circumstances, the heat dissipation fan is marked on the instructions of the radiator. Generally speaking, the heat dissipation effect of the radiator has 30% to depend on the speed of the fan, but the fan is not the higher the speed, the better.

The correct heat sink fan speed should be determined according to the HEAT of the CPU. The speed selection of heat sink fans should be differentiated according to different specifications. The basic principle is:

1, under the premise of the same air volume, the greater the fan speed should be lower, the noise will also be smaller; Generally between 3500 RPM and 5200 RPM is more conventional.

2, the greater the power, the stronger the fan wind, the better the heat dissipation effect. The power of the fan is directly related to the rotational speed of the fan, that is, the higher the rotational speed of the fan, the more powerful the fan.
