I find it hard to believe that such a tiny heatsink is enough for the 7900gt, i would expect something at least like the 7800gt, but then again the new 90nm process might help with heat dissipation quite a bit. THen again the ram chips don't have any sort of heat dissipation with that HSF, and if it's really running at 1400 i'm wondering about that just a bit. In any case if that's really stock HSF this thing will probably go sky high on overclocks with a nice nvSilencer5.
