Abstract
The present invention is directed to the detection of faulty CPU heat sink coupling during system power-up. A method in accordance with an embodiment of the present invention includes: monitoring a slope of a CPU temperature rise from initial system power-up; determining if the slope of the CPU temperature rise exceeds an expected value; and in the case that the slope of the CPU temperature rise exceeds the expected value, indicating an existence of a possible fault (PFA) related to a heat sink coupled to the CPU.
