How do 4 pin fans work?
How Does a 4-Pin PWM Fan Work? PWM can be used as a form of voltage control, and that’s exactly what it does for a PWM fan. The fan rotates according to the voltage supplied through the PWM control pin. It is also a way of providing better and smarter control for thermal management of the motherboard.
