Hello folks, I am trying to provide the best possible method of exhausting hot air from my miners in my garage. My setup now with inline fans does ok with cool temps outside, but I'm about to increase my miners from 5 to 10. My garage is underneath my home so my foundation comes up to the ceiling except for where the outside door and garage door is. I need a temporary solution for a few months and so I've been considering putting 10 miners in my doorway going to the outside of my garage. Basically I would block my doorway off with thick plywood, and make cutouts for a filter and an exhaust fan. The doorway would be enclosed by walls to try to keep things airtight. I would pull cool air from the bottom half of the door and exhaust the hot air from 10 S9 miners on the top half of the doorway with a 2500-3000 cfm fan. See concept drawing. What are your thoughts? Am I over complicating my design?

I am doing something very similar with a shed but I am allowing the exhausts to expel air directly outside and if required to install puller fan on filtered intake for fresh supply.
The plan is to try to get a positive pressure area on the intake side which can adjust itself by a variable speed fan Temperature Controller according to the exhaust temps.

I thought about the temperature controlled fan. I like the idea of the fan running at higher speeds if the exhaust temps rise. I'm concerned if the fan will compensate enough if it  is only 1 miner overheating out of 10. I have been doing some testing and I'm using a double pole relay to turn power off to one of my miners if the exhaust temp rises above 113 deg F. I need it since I can't be home to babysit these things all the time. Later down the road I could put smoke or flame detectors on the same relay circuit to kill power.
