I am proposing to build a cooler room (like at meat packing house) and run them in there. Will that work? If so how big should my room be?
It will not work, try placing a regular pc in a closed freezer and see to yourself, miners unlike dead cows generate heat consistently, you need to get rid of the heat and provide fresh cool air for your miners, what ever you have in mind won't work if it does not have some sort of ventilation.
