Abstract
The temperature sensor detects a component temperature of an electronic component included in the ICT equipment. The declination index value calculation means calculates a declination index value indicating the degree of declination of the component temperature of the electronic component, based on the detection result of the temperature sensor. As a declination index value, a declination quantity of the component temperature per unit time or a difference between the highest value of the component temperature in a past certain period and the current component temperature may be used, for example. The control means controls the number of rotations of the cooling fan in accordance with the declination index value calculated by the declination index value calculation means. More specifically, the control means causes the number of rotations of the fan to be lower as the degree of declination of the component temperature indicated by the declination index value is larger.
