Hmmm how big is the room?
It is an interesting problem since the room is sealed and there is no effort to do a true cold /hot set of aisles.
How much power do the ac units pull. You have a downclock option if too hot in the peak temps.
I allow some mixing of hot and cold aisles it actually is okay to mix the aisles a bit.
In your case you want the two aisles to mix because the room is sealed.
so if you have perfectly separated hot cold aisles the hot aisle will over heat.
worst case I see is you may need 1 split near hot aisle and space the m30s to let air mix.
bigger the room the better.
Room size is 10m*6m*3m / 32ft*19ft*9.8ft.
Each 60k btu AC pulls about 6kw worth of power, basically 1/3 of the miner's power.
Maybe a few fans sucking air from hot side back to the cold? I would imagine putting an AC in the hot side is going to melt it.
can the cold air from the split be piped to the hot side.
so 10 splits all on cold side but pipe cold air on two to the hot side.

your inside splits should have a cold ac air vent. if you tube two of them to the hot side it will mix the air.
your problem is very close but not exactly the same as what we had.
we got the cold aisle and hot aisle perfect after months of trying.
but the hot aisle was too hot 🥵. becasue we could not vent enough hot air out due to limited vent space.
so we not let some cold aisle bleed into the hot aisle.
so we were 80f cold 105f hot
with the partial mixing
we are 85f cold 95f hot
this is working very well.
you are going to have to do something like it.
your room is bigger then my room is
20long by 8wide by 20high.
some links for vents and fans as your fan idea may be good.
something like this to move some hot air to cold side.

https://www.amazon.com/Flexible-Insulated-Aluminum-Ducting-Ventilation/dp/B0BPKZ2FH7/ref=sr_1_8?what they will do is even out the room
instead of 75 cold 105 🥵 hot 🥵
maybe 85 cold 95 hot.
with no venting or very little venting mixing cold and hot will be needed to some degree.
the exact degree I am not sure 🤔
I would love to see some photos when it is setup.
