nvidia with bumblebee, doesn't speed up fan when needed.

Hey,

I have a Laptop that has a single fan that caters to both the GPU and the CPU. Sometimes the GPU will get forcefully underclocked because the fan wouldn't speed up (because the CPU load is not that high and cpu temperature is low). I haven't been able to find a patter of when this happens, though. A similar (but possibly related issue). If I exit primus/optirun app while the fan has been sped up because the GPU is hot, the fans would not speed down until I power the GPU again and they don't seem to react to the load of the machine. It's a hard problem to google and I haven't been able to find much really. Any ideas? I'm using the nvidia driver if that matters.

cheers,
