ABSTRACT:
A computer including a central processing unit, a cooling fan, an operating system (OS), a temperature sensor sensing a temperature within the CPU, a mode selector for selecting one of a fan off mode and a fan on mode for the cooling fan, a microcomputer controlling the cooling fan based on a selected mode, and outputting a selection signal corresponding to the selected mode, and a BIOS controlling a clock frequency of the CPU based on a sensing result of the temperature sensor if the BIOS receives the selection signal corresponding to the fan on mode from the microcomputer, and allowing the OS to control the clock frequency of the CPU if the BIOS receives the selection signal corresponding to the fan off mode. Here, a computer system can permit a user to turn on/off a cooling fan and efficiently control heat generated from the CPU.
