The main performance of the fan is reflected in the following aspects: speed, blade shape, blade angle and bearing system. Generally, the speed of the fan is indicated on the manual of the cooling fan. Generally speaking, 30% of the cooling effect depends on the speed of the fan. But the higher the fan speed, the better. The correct fan speed should be determined according to the heating capacity of the product, and the selection of fan speed of different specifications should be distinguished. The basic principle is: on the premise of producing the same air volume, the larger the fan, the lower the speed and the lower the noise.
