circulation would be the quesion, but some old s9s get fuckin' hot and are compatible with 110v outlets

How much do they pull though? Too much would trip the fuse in this house.
In my case a 20A dedicated circuit will power 2 miners.
I have the fan ready to go - 1st miner on the way.
Will likely add a second or a space heater style unit on other floors
I will add miners until I have to open windows ! Hahah

Draws up to 140W depending on mode 110v regular circuit. That’s very little. It mines about .35 -.50 USD / day. Not a lot of bitcoin but also not a lot of power draw. Very efficient
