Well, I got my PNY 7900GS from BestBuy earlier this week. Temps with stock cooling were 51C idle and 72C under load (looping 3DMark for a few hours). I managed to get my AeroCool VM-101 onto the card (more about that below), and the final results are 46C idle, 68C under load. Not bad, I'd say.
As far as getting the cooler onto the card, the mounting screws that came with the VM-101 are a little too big. I saw a few mentions around the net of people drilling out slightly bigger holes in their various cards to get the screws to fit. I didn't want to start drilling my brand new card, so I figured it'd be easier just to get some smaller screws. A quick trip up to Ace Hardware and all was solved. I ended up getting four sets of M2.5 screws with nuts and four additional rubber O-rings from the plumbing section. Total cost was just over 5 bucks. Plus there's the added benefit of using all four mounting arms, rather than just two like before, which should mean the pressure is spread more evenly on the chip. Something to note about the M2.5 screws--they're exactly the same size as the mounting holes, so it may seem like they don't fit (eg, they don't slide loosely through the holes). However, they thread right through the holes with no problem. M2.3 screws would probably be ideal, but I have no problem with having to thread the screws through the card (plus I didn't want to go back to Ace).
All in all, this was a good deal. Now it's time to see how far this thing will overclock...
