I am in Texas as well and have 3 Antminers and 2 Pangolin M3s which I think equal about 75 S9s
Anyway you're thinking about cooling incorrectly, what you need to think about is removing the waste heat. I made a thread called ducting check it out. The goal is to simply get the heat out of the garage. By doing just that I reduced the temp approx 30 degrees. Even the brutally hot M3s are staying pretty even.Also your CFM requirements are waaaaaay too low. Figure around 225 CFM per miner! S9s are around 5000 BTU each, these M3s are over 6000.
Garage temp at the time of this pic was ~ 75 deg F. If I had a fresh air source it would be even better and possibly help cool that HotFlash M3... But this is just a temp setup until I find a suitable building.

Here they all are in their temp duct arrangement

Thank you for the reply. I will PM you, I am in the DFW area..
I did look at your post on ducting - and yes I will take your advice and first focus on the heat waste issue - getting the hot air that these units kick out somewhere else.. I will do that first, and then address the incoming cool air issue when needed, which is likely 2 months away..
But other main issue I want to address is the noise. Of course my bedroom wall where my bed is against, the garage is on the other end. With sheetrock in between I can still hear the humming of the miners (even with some ducting). 2 miners was not bad, 6 is a little noisy..
So I am thinking of putting them in an enclosed cabinet for noise, which still having adequate in and out air flow. Anyone try this?
