Abstract:
A system for testing a fan interface on a motherboard is provided. A fan simulator receives a PWM signal from a fan interface of the motherboard, converts the PWM signal to a TACH signal and outputs the TACH signal to a computer via a fan connector. A difference between the actual rotation speed from the TACH signal and a preset desired rotation speed of the fan simulator is determined and analyzed by comparing the difference with a preset allowable error margin.
