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

mg]https://i.gyazo.com/d73e124bf0a2ce32e0198c927a095e8f.png[mg]

#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!

You could probably get better temps using a duct to get the cold air as low as possible. That way cold air would be pulled up through the rigs and out the top exhaust. You could also split the ducts and have two cold air ports, one for each shelving unit. Just make sure you have more exhaust than intake, you don't want to positive pressure the room as this might disrupt the airflow. Also might want to suggest brillow pads on the intake just for light dust,debris filtration.

Ok great suggestion, thank you!
