Default GPU core temperature in Linux

Hi all,

The nVidia embedded graphic card of my previous (less that 2 years old) Compaq laptop has died, so I'm now paying more attention to the GPU core temperature in my new laptop, a Dell M1710 with a nVidia GeForce Go 7950 GTX card.

I've noticed that, when running Linux, nvidia-settings reports about 70 to 75C most of the time even if I don't run any 3D application. This seems pretty high to me, on a most idle laptop (the CPU is less than 50 degrees)

So I booted up in Windows, installed nVidia's nTune application to be able to monitor the GPU temperature and it's about 60C. I'm fired Quake4 and played a few minutes, then check again and it was still 61C

So it appears that the GPU is a lot cooler when running Windows than Linux without any reason.

Is that an issue with nVidia drivers, or with ACPI in Linux, should I try to check/fix the DSDT table?

PS: Yes, I'm already using the latest BIOS update for that hardware.

Cheers,
Olivier.
