Is there a recommended sq ft per rig ratio? I thought 380 sq ft would be plenty for the heat to dissipate with a decent exhaust fan. We are wanting to expand but obviously can't at this level of heat.

Looking for suggestions/recommendations about heat generated through mining. We are currently running 6 1080 ti rigs (8 cards each) on 2 metal shelving units. They are in a 2 car garage with a 700 CFM exhaust fan and I'm still getting temps around 105-110 in the room with outdoor temps averaging 78-82. Any suggestions on how to bring the temp down to a more manageable number? Watched a video on youtube of a guy running his rigs in grow tents but it seemed a little sketchy to me. Anyone else doing this? Thanks in advance for the help guys.
