There is no AC Unit in that room all natural air float and ambient temperatures. I have setup the rigs to work with the room of the house. I have mined since last summers so I know to expect this summer.

I know the AC unit up stairs is not enough but the way I have engineered the rig setup the cards do not get above 80 C.

When the temperatures outside is 80 F plus I know the cards will be in the 80s to 90s the way I have setup that room. I just open the door to let the cool air from a my main room to that room. I deal with the heat like I did last year.

Also Power consumption is around 7500 Watts from the wall.
