Hi All,
I have 27 antminers in a 10x11 room on one 4 shelf rack (about 6 feet across on each shelf). See photos below. I have over 6,000 CFMs coming in and going out using (4) 3,000 CFM each gable fans. I also have (2) 14,000 BTU ACs. I've hung a tarp down the middle of the room and cut out rectangle sections where the miner's exhaust goes out (the exhaust end points towards the two 3,000 CFM fans I have that takes the air out). So the tarp is meant to create a cold/hot aisle effect. Some hot air is blowing back but I'm not sure how much.
The chip temps are all OK (mostly 60s and 70s, some 80s) but the PCB on
some of the miners are in low/mid 60s. I'm confused why some of these PCB temperatures are still so high. It's not high right now, but when summer comes, I'm nervous that it will get too hot.
Here are some pics:

Does anyone have any experience with this or suggestions on setup?
Also, I've noticed my hash rates on some of my miners have gone up a little since I've added these new intake and exhaust gable fans. The high CFMs won't hurt the miners, right?
