Zusammenfassung:	A temperature predicting unit (150) predicts the temperature of an electronic device (200) after a predetermined period, and the speed of temperature variation from the operating state of the load. Based on the results of prediction by the temperature predicting unit (150), a selection unit (140) instructs either one or both of a nozzle control unit (120) and an electric fan control unit (130) to exercise control. According to a control signal from the selection unit (140), the nozzle control unit (120) transmits a control signal to a nozzle unit (102) to drive a jet cooling apparatus (300). According to a control signal from the selection unit (140), the electric fan control unit (130) transmits a control signal to an electric fan unit (106) to drive an electric fan. The selection unit (140) selects the electric fan when the predicted speed of temperature variation exceeds a predetermined threshold, and selects the jet cooling apparatus (300) when the predetermined thresholds is not exceeded.
