ABSTRACT:
A fan control system and method that maintains the operating temperature of computer and electronic devices or components at about a predetermined control level to minimize power consumption and audible noise. The fan control system is a programmable closed loop system including a temperature sensor, first and second fan controllers, and a fan/motor assembly including a power converter, a motor, and a fan. The first fan controller provides programmable acceleration/deceleration of the fan during an initial fan spin up, and the second fan controller runs the fan only as fast as necessary to keep the sensed temperature level of a computer device as close as possible to the predetermined control level, thereby minimizing the power consumption of the system and the audible noise of the fan.
