Looks like the VGA cooler is compatible with 7 series PCI-E Nvidia video cards, but I since the cooler was released prior to the 8xxx series video cards being out, I can't find any mention of it being compatible.
I would imagine that it is compatible, but I would try and double check, or just try and find another aftermarket vga cooler that is definitely compatible.
Also, I don't trust tigerdirect at all. Use newegg, even if it's a few bucks more. (This is me giving my opinion, I know people have had plenty of good experiences with Tigerdirect)
