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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751689 Title: ThinkPads overheat due to slow fans when on 'auto' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
