摘要:
An electronic device includes a deviation value calculation unit which calculates a deviation value from the normal boundary of the relationship between a power index associated with the driving power and the measured rotational speed of the fan, a clogging detection unit which detects, based on the deviation value, clogging in an air duct through which the fan takes in air outside the case and sends it to the radiator, and a deviation value correction unit which corrects the deviation value in accordance with aging of performance of the fan to compensate for deterioration of the clogging detection capability of the clogging detection unit caused by the aging.
