So what could it run if the room is about -30C or lower?
Just curious, how do you manage that temperature?
they will be in an uninsulated garage which is rather drafty in Canada. and here it is common to get temps below -30C or even lower without a windchill. so the room will easily reach those temps soon.
I have 6 S4's running there now and they don't even pass 40C with the fans running slow
