For controlling a fan, it needs to have at least 4 wires aka PWM

2/3 wires are voltage controller fan, and the rpm range is limited, some wont spin until the supplied voltage reached 7V
unlike pwm fan can have 800 to 6000 rpm.

high speed fan is noisy and is only suitable for industry and server use, some high speed pwm fan have annoying high pitch noise even running at 800 rpm.
