Umm, that GPU cooler doesn't say it'll fit the 6950, so I probably wouldn't even look at it anyway.
Also, the cooler that comes with that 6950 is not a reference design and does its job pretty well as is.
I've build computers before.. but I've never bought a cooler.. so.. I uh.. kinda lost in this department
hey, anyway thanks dude.
btw.. what do you mean by reference design?
