Thank you for participating in this discussion. After the replacement of CPU, the problem has been solved. Special thanks to Leledumbo! He gives the Intel technical post to clarify the CPU overheating protection is not under the control of BIOS and not dependent on other sensor outside the processor. The mechanism is builtin to the processor.My initial idea is to change the BIOS to the CPU through the assembly process of overheating protection, technical feasibility, but difficult. Especially in the reverse assembly of the motherboard vendor provided Bios file. There are 2 million 300 thousand lines of assembly code.In theory, even if the temperature control set to find the code module to modify the same can not solve the substantive issues.
