ABSTRACT:
Detecting, predicting, and diagnosing faults in a cooling system. According to one embodiment, a heat sink is in thermal contact with a heat-generating electronic component. When a temperature differential between the electronic component and the heat sink exceeds a set point, a fault signal is generated. The set point may be empirically or theoretically determined. The set point may be a static set point, or it may be a dynamic set point determined according to real-time operational parameters of the system. The system may be implemented with predictive failure analysis (PFA) to provide a more reliable, efficient, inexpensive, and robust computer system.
