That's interesting you say that as it gives me a new idea. If that calculation is true then that means I could get an 80cfm bathroom type of exhaust. I could then put said exhaust in the ceiling tile (It is a drop ceiling in a warehouse) and vent the heat into the ceiling. Would that work? Does that trap the heat in the ceiling and not affect the rest of the room? It does have sheets of thick insulation in the ceiling. If that would work it would be perfect. I was initially going to vent it outside as there is a part of the room that has a wood wall that I could put an exhaust in but those types of exhaust are generally like 700cfm which would seemingly be too powerful. Thoughts?
*edit* Actually now that I think of it.  The best way to vent it out I am going to assume is to just vent it outside.

So I have an Antminer E9 Pro in a 2400cubic sq ft (8Wx25Lx8H) room. If I wanted to pull the heat from that room is there a formula that will tell me which cfm fan I should put in there? There is 1 ac vent and also 2 doors that I can partially open if need be for fresh air coming in.

I appreciate your reply. I had come across those but was unsure if that was safe to use not being familiar enough with electric. I guess since I won't be going past the full (or 80%) 20a capacity since I'll only be using that one miner. it should be fine. I will probably go that route. Thank you.

That pdu has an L6-30p plug which will not fit an L6-20r unless I'm missing something.

I bought an Antminer E9 Pro. I currently only have 1 dedicated outlet. The outlet is an L6-20r. What do I need to get to hook this baby up? I can't seem to find a pdu that has an L6-20p with built in surge protection.
