Ah, ok, thanks! Should be fine for me so far.
Edit: Didn't do the Mod so far. I just tried GPU-Z 0.3.3, and while it reads out the temperatures, it seems to be unable to read out any voltages. I don't know if that's because of the driver I'm currently using (182.08), or because of my operating system (Windows XP x64 Edition SP2).. I guess, it's the OS though. So, still no readout for me so far, latest RivaTuner can't do it either.
