Abstract: A thermal control system for an integrated circuit in an electronic device includes a sensing unit, a calculating unit, and a control unit. The sensing unit is for providing a first temperature signal by sensing the temperature of the integrated circuit and providing a second temperature signal by sensing the temperature of a component of the electronic device. The calculating unit computes a target temperature value of the integrated circuit according to the second temperature signal. The control unit adjusts target setting for the integrated circuit according to the target temperature value and the first temperature signal.
