Logging out abruptly during heavy load

Hi,

while completely unphased by benchmarking tools, my Macbook Pro 2020 i7 shows a strange behaviour.

When playing a not very graphic intense game (KSP) for Mac or Banished in Parallels/Windows the fan gets loud. After a while the games stop, it takes a few seconds before MacOS returns to the log in screen. I have to log in again. after logging in MacOS is trying to restore the previous state:

-restarting open applications including the Game or the Virtual Machine

CPU temperature is at 60 when idle and at 100 degrees Celsius during the logout event.

I opened the Mac and it seems to be clean. i cannot spot any dust.

Complete reset of the Mac with no apparent improvement.

Any ideas?

@hellomacos

To a certain degree. Ich can remove the packplate and I have the tools to perform simple tasks. I am not sure if I would want to perform a fan replacement though since it would involve removing the logic board…

Thanks

If you open it up pay close attention to the cpu area with the big silver squares (coils) if needed you may need to look on the other side for anything alarming:-)
