This is just my guess, but i think it occurs physically, not logically. By having one weaker than the other, it creates the difference. The controller is probably just sending the same thing, if you send 80% to a 4k, this results in 3.2k, but to a 6k fan it is 4.8k. Think Chinese way, cheap, make it cheaper. Control them separately? no way, that's double the effort and costs (and remember the controller actually has more, you can solder the plugs back and they all work), plug any two fans in any position and the firmware is happy You can probably use more than two, but i have no idea what is the current load limit of the poor thing.
With both being 6k but one with thinner blades than the other, i guess you get the same result with numbers looking prettier. Main reason to do that would be to save some cents with the cheaper fan motor.
I wonder how is that done with S17 4 fan configuration... Two strong and two weak?
You get negative pressure as long as your exhaust wants to move more cfm than your intake, however you do that doesn't matter. What happens if you get equal pressure? Probably nothing bad, you just are using a more expensive (and noisier) fan in the intake.
But be my guest and experiment swapping the plugs, i doubt you'll notice any difference except in the web UI fan number.
