Found this "bug" and I think I have something to say, or watch this topic.
I am using a T430 with Nvidia display. When I first installed Ubuntu 12.04 I feel that the fan is really blowing out hot air, but I can't comment on the fan speed. After I installed Bumblebee (https://wiki.ubuntu.com/Bumblebee) (a replacement for Nvidia Optimus), it seems to be able to switch off the Nvidia card so that the temperature is lowered greatly. But if I run `optirun glxgears` for about two minutes, the display card is working and the temperature rises, according to `/sys/class/thermal/thermal_zone0`, to at most `55000` (55 deg Celsius?) and the fan speed is around `3800`. Normally the temperature should be 45 and fan speed 3400. I am not really sure, but do all of you have the problem because of the Nvidia card being kept on? I don't seem to get the problem normally. (Well, the hard disk DOES get hot... but the fans doesn't seem to really help, though it seems a little bit hotter than in Windows?) -- 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
