I have all time this issue when using Ubuntus, the fan (fans?) runs most off the time and between 60%~100% even in idle which is weird. The GPU temperatures are mostly around 80 degrees and I don't think it's right :(

I always use Jupiter with power saving preset and add the line in linux default like this:

quiet splash pcie_aspm=force i915.i915_enable_rc6=1

So it helps a little (fan just doesn't run all the time 100%...)

What else can I do?

The notebook spec is:

• Core i7-720 (8 threads)
• NVIDIA GTS250M

So it's rather one of the first, not so silent and cold notebooks;), with Core i7 family and without optimus technology (as nvidia GPU is the only graphic card built-in) but anyway I don't have theese strange hot times in Windows 7.
