My laptop Samsung RF411(Geforce 540M) is overheating when i run optirun glxspheres
the temperature of the core jumps to 97C and the GPU to 72C and after some minuties the computer shutdown.
An strange thing is that the GPU in Windows goes 84C and the core stays in 86C. I think that should be a problem in controlling the fan speed.
I'm using Ubuntu 12.04, kernel 3.2.0-25-generic and the drive of nvidia is 302.17.
