CPU over-heat protection detection device
First Claim
1. A CPU over-heat protection detection device adapted to be used in a CPU having a heatsink mounted on a surface thereof, the device comprising a slot formed on one side of the heatsink that faces the CPU, a printed circuit board being received into the slot with a sensor mounted on a lower surface of the printed circuit board to be in close contact with the surface of the CPU in order to detect surface temperature of the CPU, wherein the detected temperature value is converted into a data signal by the printed circuit board, and transmitted to a system chip on a mother board on which the CPU is mounted via wires to determine whether the detected temperature is beyond a pre-set temperature value and to actuate means for decreasing the CPU temperature.

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.
