Abstract
A method for controlling and adjusting fans of the electronic apparatus is disclosed and comprises following steps: controlling a fan to operate according to a default value after an electronic apparatus is booted; obtaining operating watt value of a CPU after detecting that the temperature of the CPU reaches a set-point; inquiring one of a learning table and a pre-established neural-network data array for obtaining a PWM value and P,I,D parameters corresponding to the operating watt value; performing an error adjustment process to the obtained PWM value through a PID controller; controlling the operation of the fan according to the adjusted PWM value; storing the adjusted PWM value to the learning table if the temperature of the CPU equals the set-point; and, continuing to obtain, adjust and store the PWM value to continuously control the operation of the fan before the electronic apparatus is powered off.
