Abstract
A system and method for preventing a computer system from overheating when a processor or software controlling the processor which controls the cooling system fails. The apparatus utilizes a watchdog timer which receives periodic signals confirming proper operation of the processor. When these status signals are not received, the watchdog timer transmits signals causing the cooling system that prevents overheating of the computer system.
