Bumblebee Overheating [closed]

Solution 1:

As you said, the problem must be on the fan control. When I use optirun glxgspheres on my system it takes almost 100% of CPU, which is strange. Running with integrated card or with primusrun the cpu usage stays at ~25%. If you use Bumblebee frequently you can try to play with VGLTransport value in /etc/bumblebee/bumblebee.conf or using Primus.

But the problem should reside on all applications using a lot of CPU, and not in Bumblebee in special.

There are a lot of questions already posted here on how to control fan speed, so check them out and see if any solves your problem. Some examples:

Good luck.
