Hi guys hoping to get some feedback on my room plan:

#1 is my current plan: pull cold air in from the window and push them over rigs with fans behind each rig, then pull hot air out from the front of the rigs and use an exhaust fan in the ceiling to collect hot air and exhaust it out of the roof. This should be sufficient cooling for about the ~105 GPUs I can fit on that shelving unit

HOWEVER! I would like to leave open the possibility of expanding in the future without having to move the exhaust fan's ceiling location. So I was wondering if #2 would work if I double my size. As you can see I'd be using fans on the ground to push the incoming air up at all the rigs but I'm unsure if that 15 ft (4.5m) is too much distance to hope to carry the air.

Fwiw, I'm dealing with 75-85 Fahrenheit (24-29c) ambient temps

Any thoughts would be appreciated!

there is a danger of pulling rain water too aside of cool air from the window/s since the fans are giving them extra push.

Yeah that is a concern for me. However I have the window screen still on so that should help.

water can easily get past the screen, they just gonna get a bit smaller..try it, sprinkle some and see the results..

considered thinking about drawing air from the ceiling?...fans are still on the windows(pushing air out of it) air will be pulled from the door and ceiling as fans in the windows exhaust hot air.

Hm yeah I could do that too. I didn't even consider that I always just assumed it would be best to go from the window.

The door leads to another interior room though, that's kinda hot in general. I may be able to intake air from the roof and disperse it through ducts at ground level though. And use fans on the ground to push that cool air up.
