What are the temperature figures for the FlowFX gfFX5800Ultra compared to the standard fan gfFX5800? How efficient is the FlowFX? I was under the impression that it wasn't very good.
Flow FX is VERY effective at cooling the GPU and the memory modules on the top of the card. The modules on the bottom are, however, passively cooled. I have seen my 5800Ultra cycle the cooling fan on when the core temperature reaches about 58-60C and drop the temperature down to about 45C in less than 2 minutes- pretty effective it would seem...
As for actual thermal dissipation (numbers) I have no idea, but realize the 5800 core produces something like 72 watts of thermal power- comparable to an Athlon 2.0 Ghz CPU...cooled by a 5CFM fan (albeit a noisy one)...impressive design
