well your best bet would be too go to arctic coolings site and look at the dimensions for the cooler. Also if you can see how close the card sits to the side of the case that will help. I have the NV5 on my 6800gt and a little FYI, it takes up a PCI slot when its on the card. Not sure if the one for your card is any smaller or not.
mine doesnt no. Its shorter than the card itself. It preatty mush goes in the stock location its just thicker than the OEM one, hence why it needs an extra PCI slot.
