Abstract
Noise generation caused by sudden rising of a rotational speed of a heat radiation fan when a user has no intension is prevented. A temperature management system located on an information processing apparatus is configured by a system including a processor and scheduled tasks, a performance control system which controls processing ability of the processor and a temperature control system which includes a heat radiation fan and controls a heat radiation amount thereof. The processor executes the scheduled tasks when a state where a usage rate is low, such as an idle state, lasts. The temperature control system controls the rotational speed of the heat radiation fan in accordance with temperatures of electronic devices including the processor. The performance control system lowers processing ability of the processor before the rotational speed of the heat radiation fan rises in accordance with a temperature of the processor which executes the scheduled tasks.
