Trust me.... Me too. But it works for me for now. -- I did the heat/thermal calculations and I'd basically need 4 tons of AC in the garage to keep it at or around 68F.  So open-air/open-case for now.  Each card runs between 55C-70C depending on the ambient temperature outside.  Garage stays around 120F.


I have 200A service/load center to my house.  I added six 20A breakers to the garage just to run that batch of rigs you see in the picture.  I have Kill-A-Watt meter on each rig to make sure I'm at or below 80% load on each 20A branch.

Cheers,
Kermee
