1. A cooling fan automatic control system comprising:
- a plurality of cooling fans configured to cool a heating body;
a temperature sensor configured to measure a temperature of the heating body;
a plurality of current sensors configured to measure electrical values of current of each of the plurality of cooling fans; and
a controller which controls, based on the electrical values of current of each of the plurality of cooling fans obtained by the plurality of current sensors and a measured temperature of the heating body that is a measured value obtained by the temperature sensor, rotational speeds of the plurality of cooling fans so as to reduce a total of measured electrical values of current of the plurality of cooling fans obtained by the plurality of current sensors.

Abstract
A cooling fan automatic control system includes: a temperature sensor configured to measure a temperature of an object to be cooled; a plurality of current sensors configured to measure power consumption by each of a plurality of cooling fans; and a controller which, when a measured temperature that is a measured value obtained by the temperature sensor is higher than a target cooling temperature of the object to be cooled, controls rotational speeds of the plurality of cooling fans so as to minimize a total of measured current values of the plurality of cooling fans obtained by the plurality of current sensors.
