Abstract
A universal driving apparatus of a computer system, including a receptacle, a power switch, an integrator and a comparator, is provided to identify and drive a first fan and a second fan. The receptacle connects to the first fan or the second fan for electricity supply and system control. The integrator integrates speed signals of the first fan and the second fan to output an integrated-speed voltage. The comparator compares the integrated-speed voltage and a comparative voltage to output a comparative signal. Accordingly, the computer system uses the comparative signal to identify the fan type and actuate the first fan or the second fan correctly.
