The combination of AC power (so your CPUs will be running at max frequency) and Docker on Linux...how hot does this machine get out of curiosity? >> If you can suggest anything that I can do to collect some usefull data when >> I hit it next time, I'll be appreciated and do it. >> Try to check the thermal sensors output.
