Can you clarifies with this statement is correct ? A CPU does not shut down when it reaches the Tcase. Tcase represents the maximum safe temperature for the external surface of the processor which is different from the Junction Temperature which represents the maximum safe temperature. When TJmax is reached, the CPU will initiate a shutdown to prevent damages after some throttle cycles.

Hello Tcase,

Thank you for raising this in intel community.

To clarify your question, the statement you provided is correct. Tcase refers to the maximum safe temperature of the processor’s external surface, while Tjunction (TJmax) represents the maximum safe operating temperature for the internal cores. A CPU will not shut down when it reaches Tcase.

Instead, once TJmax is reached, the processor will begin to throttle to reduce heat, and if the temperature continues to rise, it will eventually shut down to prevent damage.

If you need more information on how Intel processors manage thermal protection, feel free to let me know and I’ll be happy to assist further.
