1. An information processing apparatus, comprising:

  • a housing;

    a printed-circuit board in the housing;

    a heat generator on the printed-circuit board;

    a heat radiator in the housing configured to radiate heat from the heat generator to the outside of the housing;

    a first thermometer in the housing configure to sense a first temperature at a first position on the printed-circuit board;

    a second thermometer on the printed-circuit board, configured to sense a second temperature at a second position away from the heat generator than the first position;

    a temperature difference processor configured to compute a temperature difference between the first temperature and the second temperature; and

    a cooling performance determination module configured to monitor whether the temperature difference is above a threshold, and to determine whether performance of the heat radiator is deteriorated based on a result of the temperature difference monitoring, wherein the threshold is at least one of;

    the temperature difference computed when a measured temperature of the housing is in a predetermined high range;

    the temperature difference computed when power consumption of the heat generator is substantially high; and

    the temperature difference computed when a temperature of the heat generator is beyond a predetermined normal operating limit temperature.
