(Get the code!)
I did another run without thinkfan and manually set the speed to "disengaged"
Top was 100°C and 4972rpm.
I watched the output of the script closely and I notived, that around 95°C the CPU throtteling kicks in and lowers the Speed from 2,6GHz to 1,2GHz. At atound 85°C it goes again to 2,6GHz. So the CPU goes faster and slower as temperature rises and falls. I guess I can kill my system faster by using GPU in addition (by just browsing the web...)
I assume that eventually at 95°C the thremal throtteling of the CPU speed is a tick to late and the fans dont respond in addition not quite as swiftly to deliver those 4970tpm that causes the >100°C. Which leads to the emergency shutdown.
From my point of view, the system is in constant thermal edge as it has to lower its speed due to overheating. I would love to see the system not exceed the temperature which would lead to speed throtteling. Which leads to the question, can a faster fan speed meet such a desired temperature and the ultimate question, why does the fan not go faster?
