I'd love to hear about the "fails" so we could possibly learn from your mistakes. I'm interested in starting a small farm like this as well. (currently, I have only 3 miners, but room for at least 10 more - need power outlets though) I have plenty of cooling (room temp of 65f/18c) but the chips are still running at 141f/60c - would be interested in your room temps and chip temps?
How does the ducting from the miner exhaust effect their chip temperature?
Now that you mention it this is actually very interesting, so in the set up i have 10xS9s running with the pipes to the ceiling and 4xL3+s just with fans there you guys have the status of one of each kind. I don't see a major diffrence but the screens are difreent too.
