I don't know what you read but your response makes little sense. I didn't say fans use zero electricity. I simply stated you don't need AC which is extremely expensive if you plan to cool a sealed room of these miners. All you need, even in a hotter climate, is good airflow from a decent quality exhaust fan or similar.
I am glad you posted, that is good information. I am in Texas as well and was planning to cool the cold side of a 40-60 miner setup (to start) in a 1,000 sq/ft warehouse. Do you have your miners set up that way or are they open with just good exhaust fans?
