M4600 IPS Quadro 2000M temperature query

I'm hoping some folk around here with a Precision M4600 and IPS display can help me decide whether to restore Windows 7, which I immediately zapped in favour of Linux.

When my machine is totally idle (i.e. static desktop), the NVIDIA X server settings show me that the temperature on the Quadro 2000M oscillates between 52 and 59 celsius causing the fan to come on for about 10s every 90s or so. The underside is fairly hot. I'm speculating that the GPU heat is the likely reason the new 6 cell battery was giving me at most 2 hours of light use. I am using the Linux NVIDIA driver (275.09.07) and wondering whether things would be improved with the Windows NVIDIA driver.

My question: under Windows, what GPU temperature/fan activity are people seeing when totally idle?

Thanks

 

I'm getting about 39°C-48°C on idle, and about 62°C- 66°C on full (GTAIV), using Windows 7 x64...

 

Well that pretty much settles it. Looks like I'll have to try Windows and VirtualBox my Linux or something

Thanks for your feedback.

BTW, the figures I gave above were when running in Adaptive mode with the GPU on power level 0 (the lowest). I can only assume the Linux NVIDIA driver is not turning off parts of the GPU that could be.
