Ok I'm not proficient at embedding images and don't feel like spending the time to figure it out. Anyways here's my setup... 6 rigs have been added since the video was shot.

like the ceiling vent and that circular fan. pretty sweet setup.
how many CFM are they?
I initially gave up on this post but thought I'd revisit and glad you embeded it for me thanks

Ceiling fan is running on low at 5,400 CFM while drum fan is running on high at 10,000 CFM. Have total of 33 rigs in this room and pulling right under 119 AMPS on ETH. Took a WHILE to get it right though. Learning curve was on electric (which I've learned from my uncle now

) and passive cooling the room. It's been quite the adventure from just jumping in the cryptocurrency field in August 2017 and have learned a lot.
