Yea heres a tip, dont buy them. They are not HOME miners. They are designed for industrial areas. If you have a waterproof garage and live in a temperate climate then you best bet is plug them in out there. Also make sure whatever electrical circuit you have them running on is able to cope with the 6Kw+ of juice they will be pulling.
Also there is nothing you can buy that will do a decent job of making them quiet. You cannot really chane the fans, you would have to build a soundproof cabinet within a room and have more fans and ducting to provide cool air and exhaust the hot. You will need to work out CFM of the existing miners then work out soze and speed of fans to supply enough airflow.
I have a car garage, but no A/C on it. Also I'm from Florida and here is very hot. Any tip how to make my garage a good fit for it?
Thanks
Being in Florida Your water table is ridiculously high, one thing you might want to look into is water cooling(swamp cooler) for the garage. Another thing you can do if you don't mind wasting your AC( if you add to your calculations it's probably going to give you a roi longer than the life of the machine) is just running a vent from the house AC to the intake of the miners in the garage( if it's attached or not too far away), they don't necessarily need to sit in the air-conditioning but they do need the cool air. I have noticed that a lot of the sound coming from the miners is resonance from all the individual heatsinks I wonder if someone could put a single copper heatsink on each hash board and make them significantly quieter.
