PROBLEM TO BE SOLVED: To provide a fan controller for an electronic apparatus capable of properly cooling even if a CPU is in a sleep state. SOLUTION: The fan controller for electronic apparatus comprises a means (30) for outputting an energy saving signal according to energy saving migration/ restoration mode (migration of a main CPU to a sleep mode, restoration mode from a power OFF of the main CPU or from the former two) of a main CPU (50), a cooling fan (40) of the main CPU, a means (20) to detect the temperature of the main CPU, and a means (10) which calculates the rotational number of the cooling fan (40), independently of the main CPU, from the detected temperature and the energy saving signal. Evan if the main CPU (50) is stopped, the rotational number of the cooling fan of the main CPU is controlled real time. |
