A system includes a CPU, a stor for storing a process executed for lowering the temperature of the CPU in association with a set temperature, a first temperature sensor for measuring a measurement temperature of a measurement position in the CPU, a second temperature sensor for detecting that a detection position in the CPU has reached a detection temperature, an offset calculator for calculating an offset as a difference between the detection temperature and the measurement temperature, a set temperature corrector for calculating a correction value of the set temperature stored by the temperature control information stor based on the offset, and a temperature control executor for executing the temperature control process in association with the set temperature in the case where the measurement temperature has reached the correction value of the set temperature. System specific thermal management data is stored in a nonvolatile memory for retrieval following system initialization.
