Shutdown unexpected run cpu stress

Hello everyone!

I would greatly appreciate the help to identify what is failing, greetings to all!

If it’s under high cpu load, have you checked the temperature of the CPU when it’s close to shutting down?

Could be overheating.

Yeah Is overheating, I just needed a change of thermal paste, they are amazing!
