The GPU (Nvidia > Quadro NVS 140M) might be an issue, nvidia-settings says 58=B0C (I am > not running any fancy graphics) and I've seen it getting over > 100-120=B0C before, when I am doing some opengl stuff.

For me the fan control was somewhat broken: I had to turn off auto-mode and set max myself to get any heavy usage out of it. You might want to check that as well. Regards Andreas
