No GPU downclock on 120hz refresh mode...affects performance?

I posted a while back that my GPU is idling at 56 ~ 64 degrees celcius...and I hit around 85 at max load ... nVidia claims the GPU can run at 105 c and still stable, they didnt realy specify the limit when damage starts to happen...in comparison the CPU's limit is at 100 c but I get 34 ~ 41 degrees celcius on idle...

I was going around nVidia's forums and I found that nVidia's drivers dont downclock to 2D mode speed when on 120hz refresh, it stays on 3D mode speed ... and its not a bug or issue...

taking it to 60hz my GPU idles at 45 ~ 52 degrees celsius (same when its running on battery) but you wont be able to use Stereoscopic 3D...

Now Im curious if high refresh rates degrade performance on games?

You can still force a downclock. At home, my dual GTX285 SLI + 3 monitors forces my main card to idle at full speed, since the nvidia drivers say "it's neccessary". However, in NV Surround, it downclocks just fine. 🙂

I use NVIDIA Inspector to boot to a profile that runs at the lower idle speeds, and nothing goes bonkers on it. I just restore the normal high-speed profile when I want to game.
