1. An electronic device with a fan built therein to perform air-cooling by an air flow generated by rotation of the fan, comprising:
- an accumulated rotation number calculating section which calculates an accumulated rotation number of the fan;
a determining section which determines whether the accumulated rotation number calculated by the accumulated rotation number calculating section exceeds a predetermined threshold value; and
a warning section which gives a warning in response to a determination result that the accumulated rotation number exceeds the threshold value, the determination result being obtained by the determination section.

Abstract
A rotation number calculating section calculates rotation numbers per unit time on the basis of pulse signals, a CPU calculates an accumulated rotation number on the basis of a sum of products of the rotation numbers read at a predetermined time interval and the predetermined time, determines whether the accumulated rotation number exceeds a predetermined threshold value, and gives a warning aiming at urging a user to clean a fan in response to a determination result that the accumulated rotation number exceeds the threshold value.

5. A program storage medium in which a program executed in an electronic apparatus with a fan built therein to perform air-cooling by an air flow generated by rotation of the fan is stored, the program storage medium storing the program which causes the electronic apparatus to operate as an apparatus comprising:
-
an accumulated rotation number calculating section which calculates an accumulated rotation number of the fan; a determining section which determines whether the accumulated rotation number calculated by the accumulated rotation number calculation section exceeds a predetermined threshold value; and a warning section which gives a warning in response to a determination result that the accumulated rotation number exceeds the predetermined threshold value, the determination result being obtained by the determining section.
