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?)
