If you are planning on sleeping in the same room as your miners make sure it is very limited, make sure the heat is very minimal, maybe I wouldn't have faced this if I stopped at my first 400MH mining rig. While BTC is your goal always look out for your well-being too.
I never knew that one could get this kind of health challenge from being in the same room as their mining rig. First sorry about it. I'm glad you now know better. Also, thank you for letting us know about this. At least now I know better and I would keep it in mind both for myself and for advice for anyone who plans to do this as well. Lastly, if you can, limit going to the rig for now. If there's someone that can do it in your place that would be great.
1GH of Ethereum hashrate and S19 Asic miner is a very small amount of equipment to be near it constantly. 1 I had more than 1GH and sometimes I did not approach the video cards for more than 3 months, but watched remotely.
