PROBLEM TO BE SOLVED: To continue thermal management when a plurality of heat radiation fans partially fail.SOLUTION: Heat radiation units 101, 201, 301 respectively including heat radiation fans discharge heat of a GPU 11, and CPUs 21, 31. When the three heat radiation units are normal, first thermal management is executed to control the rotational speed of the heat radiation units and the performance of an information processor. When any of the heat radiation units fails, a heating value is suppressed more than the first thermal management to exchange second thermal management in which a rotational speed is increased. The heat radiation unit can be inspected during booting. The use of the information processor can be continued even though any of the heat radiation units fails by introducing the second thermal management.SELECTED DRAWING: Figure 2 |
