ABSTRACT:
An over temperature protection method and its circuital device for a central processing unit includes a read and write memory unit having pre-stored therein; an instruction for identifying a type of CPU and automatically predetermining the maximum allowable over temperature for the CPU. An over temperature is detected by a heat sensitive resistance installed at the space immediately under the CPU to cause an audio frequency alarm circuit to output a sound alarm and also cause the CPU to slow down its operation speed to an appropriate reduced rate to prevent CPU from being damaged by over heat or other loss caused by interrupting CPU operation. After recovery of temperature to a normal value, the CPU can be instructed to operate with its normal speed.
