Abstract
Provided are a fan control method and a fan control system. The fan control method of the present invention includes the steps of predetermining a reliable operating temperature of a hard disk; creating a storing a corresponding relationship between an average hard disk temperature and a fan speed, and creating and storing a corresponding relationship between a hard disk temperature greater than the reliable operating temperature and a fan speed; reading actual temperatures of the plurality of hard disks; comparing the actual temperatures of the plurality of hard disks with the reliable operating temperature; computing an average temperature of the plurality of hard disks; and outputting a control signal to adjust the fan speed based on the stored corresponding relationship between an average hard disk temperature and a fan speed. Accordingly, the present invention may increase hard disk reliability and decrease power dissipation of a fan and system noise.
