They can't be piped by default, but with some ducting it could we could easily direct one or more ACs to blow air to the hot side of the room, sould not be too difficult to do.

Here is how thet look like https://www.daikinindia.com/products-services/floor-standing

They blow air from the bottom and blow at the top.

How did that affect the gear temps? It's hard to know if gear would prefer 80f intake and 105f out, vs 85f in and 95f out.

@stopmix, whatsminers would tune lower when temps go up, not much work needed to underclock them or shut them down when needed, but the cost of the setup will be close to 20k, slightly above, would rather size everything correctly since this will be one huge risk to test.

My plan is not to go full blast at first, so maybe just 1-2 ACs and the right number of miners accordingly، that should give us a good overview of how things will be on a larger scale.

The next issue we would face is noise, we need to soundproof the room as much as possible, also not sure how noisy a dozen ACs outdoor units will be.

This is going to be a very complicated project to say the least, which is why I am trying my best to be prepared for all scnerio, have to study everything, consulted a few HVAC folks and none of them had a clue of an operation of such type, they all know the math as we do, but none seemed to fully guaranteed it would work.
