<P>PROBLEM TO BE SOLVED: To provide a cooling device capable of efficiently cooling the inside of an electronic apparatus by controlling a fan in accordance with variations of the temperature in the electronic apparatus and a power voltage. Ž<P>SOLUTION: This cooling device includes: the fan for cooling the inside of the apparatus; a temperature detection part detecting the internal temperature of the apparatus to output a detection voltage according to the temperature; a drive part driving the fan; and a control part controlling the operation of the fan. The control part includes: a temperature monitoring means to monitor the temperature in the apparatus based on the detection voltage; a voltage monitoring means to monitor the power voltage supplied to the apparatus to calculate temperature variation in the apparatus caused by the variation of the power voltage; a correction means to correct the temperature in the apparatus monitored by the temperature monitoring means based on the temperature variation to calculate a correction temperature; and a first comparison means to compare the correction temperature with a first threshold value. The operation of the fan is controlled based on the comparison result. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
