@sven said in Processor overheat:
…(without the drivers nVidia and Bumblebee because I had black screen)…
So probably you have experimented with Bumblebee and got bad results, haven’t you? How did you remove Bumblebee? Did you re-install Antergos from scratch?
Bumblebee (bbswitch) switches Nvidia GPU ON and OFF automatically. If Bumblebee was not configured properly, or was not uninstalled correctly, it may leave Nvidia GPU switched ON, which is wrong.
If the system constantly runs on Nvidia instead of Intel, it gets overheated, independently from CPU usage.
Just a guess.
