I understand your pain. I had the same problem mining bitcoin. I ended up making a large enclosure to house all of my miners. I then put the A/C I wanted to use in my boys room and cut out a 200 square inch by 6 inch deep piece of evaporative cooling panel and used my antminer s9's strong fans to pull air out of the enclosure. I tell no lie, I swear. We recently had 2 115 degree days and my miners where around 194. Where I live has very low humidity in summer and the only things I have had trouble with are the stupid bitmain 1600w PSU's which are just plain dumb and don't last 12 months.
