using connections on same side as space requires. I can see how supply/return to upper/lower would matter on gravity, but what about on circs?

    It still matters, but not as much -- and it's dependent on the flow rate. If you have a very low flow, then it matters a lot. If you have a high flow, then there's enough turbulence in there to achieve mixing and it doesn't matter.
