Variable-speed fan controllers for computers usually use PWM (Pulse-width modulation), as it is far more efficient when compared to the traditional one. The PWM technology allows the 4-pin fan to be more temperature-sensitive, so that the turning-speed can be adjusted automatically over the BIOS setup if your mainboard supports this specification.
