==Comparison of different sizes==

I've selected a representative 120mm, 140mm, and 200mm fan (coincidentally, these are the same three sizes of Noctua fan that can be placed as designed into a MO-RA3 external radiator). Note that the 200mm has less than half of the static pressure of the other two fans, though it moves more total air (at ~~less~~ RPMs, and more quietly).

I've selected a representative 120mm, 140mm, and 200mm fan (coincidentally, these are the same three sizes of Noctua fan that can be placed as designed into a [[MO-RA3]] external radiator). Note that the 200mm has less than half of the static pressure of the other two fans, though it moves more total air (at fewer RPMs, and more quietly).

Line 163:

The maximum power draw is the 9x120mm setup at 15.12W of 12V power. A SATA power cable provides 3 pins of 12V power at 1.5A each, for a total of 4.5A of 12V power, 54W. A single SATA power cable at spec ought be able to more than sufficiently power even a push+pull 18-fan configuration. The calculation changes if pumps are also involved, of course. Either way, everything here ought be 12V.

So which configuration is best with a MO-RA3? While it depends on the installation's needs, I'll likely go with the 9x140mm. I could make an argument about it running at less than maximum speed and still moving more air, so who knows how loud it would be, but mostly I just don't want unsightly gaps in my radiator coverage lol.
