I have 10 Bitmain S19 pro miners, and I had a lot of problems with heating, where they first run at about 70-90 degrees, but after a couple of days some of them will have shut down from overheating. Trying different placements I managed to reduce the number of miners that shut down, and lowered the temperature some, but overheating always ends up being a problem.
My first solution when I started mining was to get a big ventilation, but I quickly concluded that the room was too hot.
Ventilation:
After that I tried to attach tubes to each miner that went to the ventilation, and the temperature in the room was normal, but the temperature in the tubes was too hot because the ventilation was not exhausting the hot air quickly enough to the outside.
Improved ventilation with tubes:
I also want to expand with moreA miners, and the ventilation can hardly support more miners, so I was thinking of connecting tubes attached to the miners directly to the window, possibly with negative pressure fans to further help exhaust the hot air.
I figure this might not be sufficient, and the problem with the miners attached to the ventilation remains, so I was thinking about making a wooden box for the miners and has a hole that connects with a tube directly to an airconditioner. That way I get a flow of cold air from the outside, while exhausting the hot air to the outside. I am concerned about dust and moisture coming from the outside.
Now the question is if this is sufficient? And is there any better solution? Or maybe a cheaper one? Having a big airconditioner run 24/7 is after all very expensive.

the main vent can not move 10 x 500 = 5000 cfm
I can tell by the size it is.
in order to move 5000 cfm you need a minimum 24 by 24 inch opening with a power fan straight out of a wall opening or a window.
i will find a link.

those vents above are 18 by 18 and do 3000 cfm you need two of them.
in a wall with zero resistance to send air outside.
your main vent looks like it is 18 by 30 inches .
right there that is too small. for 10 pieces. try running five units see how it does.
