Abstract
A fan operation adaptive control system is proposed, which is designed for use with an electronic system, such as a network server, for providing the network server with an adaptive operation control function; and which is characterized by the utilization of a CPLD (Complex PLD, where PLD=Programmable Logic Device) module for implementing the adaptive operation control function for various different types of fan units, including PWM-driven type (which includes 100 Hz–500 Hz, 10 KHz–50 KHz, and 1 MHz–5 MHz subtypes) and DC-driven type, such that the network server can be equipped with just one type of temperature sensor which can be used in conjunction with these various different types of fan units. This feature allows the maintenance of heat-dissipating fan units on network servers to be more convenient and cost-effective to implement than the prior art.
