制御装置。[Scope of claim for utility model registration] (1) In a cooling fan that cools the inside of an electronic device, etc., the internal temperature detected by the temperature detection section remains constant even if the ambient temperature changes. A rotation speed control device for a cooling fan, characterized in that the rotation speed of the cooling fan is controlled by changing the voltage of a power supply supplied to the cooling fan so as to maintain the rotation speed of the cooling fan. (2) The set value can be adjusted continuously using a volume or in stages using a switch, so that it can be adjusted to suit the system configuration of the electronic device, the place of use, and the conditions of use. A cooling fan rotation speed control device according to claim 1 of the utility model registration claim.
