ABSTRACT:
Disclosed is a CPU over-heat protection detection device in which a slot is formed on one side of a CPU heatsink, and a printed circuit board is placed into the slot. On the lower surface of the printed circuit board is mounted a sensor which detects and measures the surface temperature of the CPU, and converts the temperature value into a data signal which is transmitted to system chip of mother board via a wire so as to determine whether the measured temperature is beyond a preset value. If an over-heat state occurs, through the control of system chip, either the CPU temperature is decreased or a warning device starts to run in order to protect the CPU from burning down due to over-heat.
