Abstract
A multi-fan speed single-wire output system and a method thereof are disclosed. The system includes at least one first fan and one second fan, which have a first and a second rotation speed, respectively. The first fan transmits the first rotation speed to the second fan, and the second fan performs a logical operation on the first and the second rotation speed to generate an output rotation speed.
