A heat sink having auto switching function, a heat sink system and a heat sinking method are disclosed. The heat sink receives a control command sent by an external device. An internal heat sink device is controlled according to content of the control command to control power ON or power OFF of a thermoelectric cooler of the heat sink device or to control power ON, power OFF, or change rotation speed setting of a heat sink fan in the heat sink device. Thus, the heat sink auto switches operations of the heat sink device correspondingly according to temperature changes of the external device.
