Having a blast in the cold with t21 mods

So I've got a one-board and a two-board t21 setup in my unheated garage attached to the house. It got super chilly in New Jersey today, about 20°F or -6°C. These two machines are slightly underclocked and even in this cool garage, they’re supposed to be 19-watt units, but they're actually pulling around 16.6 watts each, which is pretty solid. Getting about 164-165 TH/s while consuming around 2730 watts.

cranked them up a bit the 2 board is set to 192th which is an overclock as 190th is stock

Nice do you have also stable operation result ? Like few months of stable operation on that mode?

how does it look
