摘要： A disclosed air conditioning control system includes an electronic apparatus including a heat generating component, a fan that supplies cooling air to the electronic apparatus, and a controlling unit that controls the number of rotations of the fan. The controlling unit controls the number of rotations of the fan by predicting a future temperature of the heat generating component, such that the temperature of the heat generating component lies within an allowable range, in a first case where a rate of rise in a consumed electric power of the electronic apparatus is smaller than a first threshold. In a second case where the rate of rise is equal to or larger than the first threshold, the controlling unit switches the control of the number of rotations of the fan to a control in which the number of rotations of the fan becomes larger than that in the first case.
