Hows the heat? I cant imagine that box fan is enough.. I need a humidifier im dealing with hot dry air.
Ambient for the room is ~50F, and most of the cards are between 55-65C.
It's winter in New England, and there's a filtered box fan in the window to the right in the pic, behind the rigs. It's blowing 0-20F air into the room, and the cards are nice and cool!
We have 50kBTUs of AC ready to go, but we're holding off while we can, cuz a box fan is cheaper.

Nice RIG

Thanks!
I hate you. Tomorrow will be the coldest day of the last 10 months here in SoCal - get down to a chilly 49F at night. I swear God mad this the hottest winter in history on this side of the US.
