The Zalman does fit the card... and the case problem is mostly a heat issue (the heat has no where to rise and I can't put the optional fan on top as they recommend). The Zalman cooler did spread the heat evenly... but it got way too hot to even touch AND THAT WAS WITH NO 3D but just sitting at the windows screen. It would reboot every 5-10 minutes.
The arctic cooling solution doesn't look like it will work because of the face-plate replacement. It looks like it clears the tuner, but they replace the metal faceplate with one that works for the non-AIW version, but not the AIW.
I've given up passive cooling... now I just want quiet(er) active cooling. My guess is the Zalman product would work great in a normal mid-tower.
I have a free almost completely brand-new Zalman VGA cooler for anyone who can help me fix my problem!
