GeForce 820M running very hot in Ubuntu

[Lars Hansson]

Ubuntu release: Ubuntu 14.10
Wine: 1:1.6.2-0ubuntu6
GPU: Intel HD 4000+Nvidia GeForce 820M
Nvidia drivers: nvidia-331-updates

Expected behaviour: GPU temperature should not be excessively high when running OpenGL games.

What happens: The GPU temperature gets very high when running OpenGL games. For example, running "The Talos Principle Public Beta" from Steam in Ubuntu the GPU temperature will go up to 95-98C but running the same in Windows 8.1 (on the same laptop) the temperature stays below 80.
The same thing happens when running other games and games in wine.

Lars Hansson, thank you for reporting this and helping make Ubuntu better. Could you please execute the following in a terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1391422

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

I've exactly the same problem here. My laptop is a DELL Inspiron 3000 Series: I14-3442-A40. My GPU is a Nividia 820M (2GB, 64bits) I'm playing the game Fight the Dragon (via Steam) and my temperature reaches 93 degree Celsius (°C). The same happen when I play Civilization V (also via steam) or X-Plane 10.

Actually, I think I know what the problem is. The 820M is one of those card with a boost feature and on Windows the driver will boost until the GPU temperature reaches 70C, then the driver will start downclocking the GPU. On Linux this feature seems to be missing, the driver never downlocks and the card will boost until either powerclamp starts injecting insane amounts of idle time or (if you have disabled powerclamp) the temperature reach the thermal limit (~96C).

Hi Christopher.
I tried running the apport command but I'm having the same issue as in this bug report:

Lars Hansson, could you please boot into a live environment via http://cdimage.ubuntu.com/daily-live/current/ and then run the apport-collect?
