So here is what I currently have going on ...
31 GPU's ranging from 1070ti's to 1080ti's ... Six of them are XFX Vega 56 blower cards. According to fan specs, we're doing 3100ish cfm on intake and exhaust in a room that is 1680 cubic feet. There is another window in that room that I could put another intake fan in, not sure about that yet. If I do that, I assume I'm going to need to put in another exhaust fan. All rigs other than the vega blower card rig have a box fan behind them.
I'm wondering if I should move the shelving unit a little closer to the exhaust, so the heat is sucked directly upwards, but the box fans are pushing hot air off of the cards in a forward motion. Not sure how much.
Currently the room is around 7-8 degrees above the outdoor temp. Without the exhaust fan (and with the intake and box fans), it was 15-18 degrees above the outdoor temp, so it has certainly made a big difference.
Temps here are going to be heating up, so we will see what happens. The next step in this project is venting all the way outside rather than into the attic.
If anyone has any suggestions on gable vents or roof vents that have fittings for a large diameter hose, please let me know.

Yeah, I found I had to make different rooms for best efficiency possible. A room for heat and a room for cool. You cannot allow the heat generated by the rigs to mingle with fresh cool air. Otherwise, it will heat up the cool fresh air before it is sucked into the fan which blows warmer air onto the rigs. The rig gets warmer; the air coming off the rig gets warmer, the room air gets warmer; the warmer room air blows on warmer rigs to release even warmer air in a big circle like a convection oven recirculating heat. At least this is what I determined once I got over 100 cards. I have over 200 cards now.
No idea on who to contact for the roof vents. Good luck. My dad had to rig stuff up his own.
