Just wondering if there's a firmware, driver or other reason why a BFG 7900 GT OC seems always to hiss away in Vista 64-bit. I have 7900GS's running under Vista 32-bit and they do seem to spool down the fans to a reasonably silent level in normal, non-GPU-intensive use.

I've just recently re-installed this card after a long period of non-use, where it was on an XP box and I could swear it was a whole lot quieter under XP. Any tips for noise reduction? Thanks.
 
Have you tried Rivatuner?
If that doesn't work you can always get a new heatsink. It's not like they are that expensive.
 
Haven't tried Rivatuner yet. As I said, I don't recall having this problem in XP and I just wondered if Vista drivers had issues with fan control and if there was a fix for it.
 
It's not a driver issue, it's whether the board maker spent the couple pennies it cost to add the fan control to the 7900. Not many had them - and some (like XFX?) had models that went 100% fan speed in 3d mode. Out of 3 eVGA (7900gt) cards I've had, I think maybe one had fan control. And it was a higher end card - rebadged SS card (RMA return card), during the 'fiasco' which didn't last long unfortunately.

If you can't get Rivatuner to take control of the speed for you, you pretty much have 3 options:
1) Use Nibitor and edit the preset fan speeds manually, and reflash << voided warranty
2) New 3rd party cooler
3) Just live w/ it
