What are the advantages of utilizing cooling fans with PWM speed regulation?

What is PWM speed regulation?

PWM speed regulation refers to a technique for controlling the rotational speed of a Fan by adjusting the duty cycle of its supply voltage. A higher duty cycle results in faster fan rotation, while a lower duty cycle causes the fan to rotate more slowly. This method enables continuous and stepless speed regulation,thereby significantly improving the energy efficiency of the fan.
