Abstract:
1. A cooling controlling apparatus that cools an electronic apparatus, comprising: a cooling fan that discharges air in an inside of the electronic apparatus to an outside of the electronic apparatus; an intake air temperature detector that detects a temperature of air taken into the electronic apparatus by the cooling fan; a part temperature detector that detects a temperature of each of a plurality of electronic parts arranged inside the electronic apparatus; a threshold value storing unit that stores an intake air temperature threshold value and a plurality of part temperature threshold values each provided for each of the plurality of electronic parts, respectively; and a fan controller having first and second modes and that controls a rotation number of the cooling fan based on a result of comparing the intake air temperature detected by the intake air temperature detector and the stored intake air temperature threshold value when the fan controller is in a first mode, that performs at least one of increasing and decreasing the rotation number of the cooling fan using a predetermined variation ratio by detecting whether or not the temperature detected by the part temperature detector is equal to or less than each of the plurality of part temperature threshold values provided for each of the plurality of electronic parts, when the temperature of each of the plurality of electronic parts is in a predetermined condition and the fan controller is in a second mode, and that stands by to progress to a next process for a first time period after performing one of the increasing or the decreasing the rotation number.
