Abstract
The inventive fan includes a frame having a hub defining an aperture and a fan unit received in the frame. The fan unit has an air impeller rotatably supported by the hub and a circuitry adapted to adjust the rotational speed of the air impeller. The heat sensor extends from the fan unit to the heat sink through the aperture of the hub, and sends a signal indicative of the precise temperature of the heat sink to the circuitry for the adjustment of the rotational speed of the air impeller. As a result, the rotational speed of the air impeller can be changed upon the precise temperature of the heat sink detected by the heat sensor.
