Abstract
A fan speed control system includes a fan, a hardware device, and a basic input/output system (BIOS) module. The BIOS module includes a memory unit, an edit unit, a searching unit, and a control unit. The memory unit stores a matching table of different hardware device numbers and corresponding fan speed control curves. The edit unit is operable to edit the matching table. The searching unit is operable to read the matching table and search which fan speed control curve matches with the hardware device number of the hardware device. The control unit is operable to select the matched fan speed control curve to control the fan speed of the fan.
