Abstract
A cooling device detection circuit and method for detecting a cooling device in a computer system. In one embodiment, a cooling device detection circuit includes a detection stage and a power management stage. The detection stage is configured to sense an indication that the cooling device is functioning and to assert a signal if the cooling device is detected. The power management stage is configured to turn off a component cooled by the cooling device if the cooling device is not detected.
