Abstract

The disclosure refers to an electronic device and methods for cooling an object within the electronic device. In one example, an electronic device includes a cooling fan for cooling an object. An air-quantity measuring device measures a quantity of cooling air sent by the cooling fan. An ambient-temperature measuring device measures an ambient temperature around the electronic device. A control unit is configured to control the electronic device. The control unit includes an object-temperature calculating section configured to calculate a temperature of the object from the measured air quantity and the measured ambient temperature. An operation control section is configured to control the cooling fan according to the calculated temperature of the object.
