Abstract: An air volume control device determines whether or not a cooling capacity of an electronic device fulfills a predetermined cooling capacity. Then, if it is determined that the cooling capacity of the electronic device is failing to fulfill the predetermined cooling capacity, the air volume control device decreases the number of revolutions of a fan for cooling the electronic device. For example, the air volume control device compares a temperature of a heating element provided in the electronic device before a change in the number of revolutions of the fan with that after the change in the number of revolutions of the fan. If the temperature of the heating element is increased when the number of revolutions of the fan is increased, the air volume control device determines that the cooling capacity of the electronic device is failing to fulfill the predetermined cooling capacity.
