Thank you for that, haven't been aware of such ultra low critical temperature.
I guess that would take some research why it is so, and probably the BIOS modification would be needed here - what obviously could lead to problems with RMA and bricked card in the end.
Plus, I'm bothered about the extra investments in power supply and electricity bills - I guess that it is important if we are building something near 24/7 or rather from time to time password cracker.
Regarding the 7970 - I guess it can be only accepted as an option if you have somehow soundproof room in which the machine will operate. I had 7970 (with some kind of "ultra silent" non reference cooler) and it was hard to sleep in the room behind the wall when I did computing on it :-)
Not exactly sure why we talk only ATI/AMD - what would you guys say about the nVidia propositions, like 970 or even a 750Ti?
