<p>A control device for controlling a personal computer cooling fan, which comprises a temperature sensor and a control circuit intended to supply the fan with a voltage in response to a signal received from the temperature sensor. The invention is characterized by the combination that the control circuit (1) is intended, when the personal computer concerned is switched on, to supply the fan (2) with a voltage which is higher than its idling voltage over a limited, predetermined period of time, and that the control device (1) has a dimension of at highest about 4 x 3 cm and a thickness of at most about 1 cm, thereby enabling the device to be placed in the housing (5) of the fan (2); and in that provided between the control circuit (1) and the sensor body (6) of the temperature sensor (3) is a rigid electric conductor (7') having a length sufficient to enable the sensor body (6) to be placed in the airflow through the fan (2).</p> |
