I think your acoustics chart may be mislabeled; the IceQ 69
70 is shown as the quietest card.
On another note, I recently purchased an IceQ 6970 and I love the thing... Went through a bad experience with a reference XFX 6970 that shorted out when I plugged in the HDMI. The difference in subjective noise levels is CRAZY, and the thermals are about what you guys found.
Also I find the thing quite stylish

, especially when illuminated by a blacklight.
Didn't read the whole review, as I'm about reviewed-out on this card already, but someone should mention that
the humongous cooler intrudes upon the 3rd slot, so close-proximity CrossfireX is a no go.
I'm selling the thing now, as I want crossfire upgrade-ability for the future... After this whole damned fiasco I might just move to the green team. I've been gazing longingly at all the TWIMTBP love that those guys get while I'm stuck in Crossfire driver hell
