Abstract
In an information processing apparatus, a heat-generating portion including at least a CPU is cooled by circulation of a cooling liquid, the temperature of the cooling liquid is measured and the operating condition of a pump for circulating the cooling liquid is obtained in accordance with the measured temperature of the cooling liquid. The pump is operated on the basis of the operating condition to control the flow rate of the circulated cooling liquid. Further, even after the system for the information processing apparatus stops, the circulation of the cooling liquid is continued until the temperature of the heat-generating portion becomes not higher than a predetermined value.
