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.
