Fan Speed Of Centrifugal Fan

Fan speed refers to the number of times the fan blades rotate per minute, in rpm. The fan speed is determined by the number of turns of coils in the motor, the working voltage, the number, inclination, height, diameter of fan blades and the bearing system Co-determination. There is no inevitable connection between speed and fan quality. The speed of the fan can be measured through internal speed signals or external measurements (external measurements are made using other instruments to see how fast the fan is rotating, while internal measurements can be directly viewed in the BIOS or through software. Internal measurements have relatively larger errors).
As the application situation and environmental temperature change, different speed fans are sometimes required to meet the demand. Some manufacturers have specially designed radiators with adjustable fan speeds, which can be divided into two types: dynamic and automatic. The main purpose of manual operation is to allow users to use low speed for low noise in winter and high speed for good heat dissipation in summer. Automatic temperature regulating radiators generally come with a temperature control sensor that can automatically control the fan speed based on the current operating temperature (such as the temperature of the heat sink). If the temperature is high, the fan speed will increase, while if the temperature is low, the fan speed will decrease to achieve a dynamic balance, thus maintaining a combination of wind noise and heat dissipation effect.
