PROBLEM TO BE SOLVED: To provide a cooling system for electronic devices that can use all the cooling fans as long as possible. SOLUTION: The cooling system has two or more cooling fans 6 and two or more temperature sensors 7. Further, it has a heating member detector 8 for detecting whether or not a heating member is loaded and a fan selection section 9 for selecting a cooling fan 6 corresponding to a heating member loading section loaded with a heating member. It also has a number-of-revolutions indicator 10 for changing the number of revolutions of the cooling fan 6 selected by the fan selection section 9 according to the temperature detected by the temperature sensors 7. In case the driving condition of the cooling fan 6 does not change for a certain period of time set in advance, the number-of-revolutions indicator 10 rotates all the cooling fans 6 at a relatively low number of revolutions.
