@ recent debate
I highly doubt bitfury will go for immersion cooling (atleast not in the short term).
Bitfury rigs are specifically designed for free air cooling, with input temperature requirements of only under 35°C, still reaching 0,785W/GH at this level.
The devices are 6U 3.5TH, so they do use some space.
i agree, ive seen nothing to support immersion cooling for bitfury. that said, they have the funding and a quality chip design that could be converted for IC
@bitmaintech
Apparently they have recieved their 28nm chips (earlier than what i would have expected, my guess was July)
Power consumption at chip level 0.59W/GH, at normal clock frequency.
This should translate to about ~0.73W/GH at the wall if they use high quality components.
While this is an okay design, Spondoolies can reach that with an sp10 clocking at 1 TH on their 40nm chips.
the S3 is scheduled for 505GH/390W, or about 0.78w/GH (0.6w/gh at chip level) at maximum speeds. Undervolting by 0.1V will improve the efficiency to about 0.6W/GH (0.4w/GH at chip level). Its possible that further undervolting may be possible but bitmain has only given so much info thus far. No sign of IC, but they are geared towards users seeking less density/noise
