Claim Text:
1. An electronic device including a cooling fan, at least one temperature measurement unit, and a temperature control unit which controls a rotation speed of the cooling fan based on the measured temperature measured by the temperature measurement unit to control the temperature inside the device characterized in that the temperature control unit stores at least a plurality of measured temperatures that are measured at predetermined time intervals in the past in chronological order from the latest measured temperature, stores a normal temperature range for each temperature measurement unit, determines the presence or absence of a temperature increasing trend based on the plurality of measured temperatures and the latest measured temperature that are stored, shortens the time interval between temperature measurements from the current time interval when it is determined that the temperature increases, determines whether or not the plurality of measured temperatures and the latest measured temperature are included in the normal temperature range when it is determined that the temperature does not increase, prolongs the time interval between temperature measurements from the current time interval when all the measured temperatures are included in the normal temperature range, and does not change the time interval between temperature measurements when at least one measured temperature is not included in the normal temperature range.
