Abstract:
1. An information processing apparatus comprising: a cooling fan; a temperature acquiring unit; a first control unit configured to immediately accelerate a rate of the cooling fan to a first rate when a temperature acquired by the temperature acquiring unit exceeds a first temperature and the rate of the cooling fan is less than the first rate; a second control unit configured to immediately accelerate the rate of the cooling fan to a second rate faster than the first rate when the temperature acquired by the temperature acquiring unit exceeds a second temperature higher than the first temperature and the rate of the cooling fan is less than the second rate; and a third control unit configured to decelerate the rate of the cooling fan every time a predetermined time passes after the rate of the cooling fan is changed when the temperature acquired by the temperature acquiring unit is less than a third temperature lower than the first temperature, so that a decelerating rate is smaller than a rate difference between the first and second rates.
