I don't know of any formal heat test. I did sometimes have the impression that the problem wasn't as bad at times, but it did get worst in general. It is a bit of a mystery to me what exactly was wrong with the laptop. The fan itself seemed fine, maybe it was the thermal paste or whatever.
The fan replacement definitely helped here. Right before the guy came to replace the fan I could get the machine to shut down by compiling GTK+. Right after the fan was replaced I did the same test and the temperature reached just over 70°C (cold laptop though). I just repeated the same thing (compile GTK+ four times or so) and the temperature was mostly below 80°C. I have *not* seen *any* CPU throttle events or similar since the fan was replaced. And I saw similar errors as mentioned above. I also had some errors that stated that the CPU was drawing too much power. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009731 Title: Since 12.04, CPU is overheating and powering off spontaneously under high computation load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thinkfan/+bug/1009731/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
