A multi-fan control device according to the present invention is to control a multi-fan installed on an electronic device such as an archive system by a simplified configuration. For example, a NOR circuit as a logic element circuit with a simple configuration is used instead of removing a controller and a comparator. Further, a transceiving process of a signal can be simplified as well as the multi-fan control device can be reduced in size efficiently by outputting a control signal of pulse width modulation (PWM) in a microcomputer and directly controlling the multi-fan. |
