Very interesting. Of course, long before that I strapped a ThermalTake Big Typhoon onto my X1800XL, so it only seems natural, given the high thermal load current CPU coolers can handle. That said, that's one awesome picture, without a doubt. Makes me want to put my Noctua NH-C14 on my 6950 2GB. Hmmm...got a thermalright 2900XT cooler, which has the same 45 degree twist to the chip. Wife is home on vacation...could be an interesting project, except I already got real water on my "play" HD6950. Thanks very much for the link, really!
