Seems to have been something with the fans because my temp raised about 20C in both idle and 3D mode.
No, I doubt the fans are running any lower. Think about it. There are dozens of different fan types, many probably going at different speeds, some cards have 1 fan, some have 2, etc. I actually think the card is running hotter, probably because they are doing something different with card power management. A driver fix for this is truly impressive, proves Nvidia have the best drivers in the world. I was amazed at just how easy my Nforce2 board was to set up driver-wise. Even easier than my Intel D875PBZ, and that's saying something.
