What are the factors that can affect the speed of the cooling fan?

When customers purchase a cooling fan, they are more concerned about the air volume and noise of the product. What are the factors that affect the speed of the cooling fan.

For the same size, voltage, and fan speed, the noise and air volume generated will also vary. Fan speed refers to the number of times the fan blades rotate per minute.

The speed of the fan is determined by the number of turns of the coil inside the motor, working voltage, number of fan blades, inclination angle, height, diameter, and fan bearing system. In the fan structure.

In some cases, the speed of the fan will vary with the variation of the working voltage, and the speed of the fan can be measured using a dedicated infrared tachometer.
