Radiator surface area reccomendations

[CodeMaestro]

I am in the process of designing a computer desk case for myself for my next build. I'm planning on liquid cooling a 6700k and two Flagship-tier Pascal GPU's in SLI (1080ti?) in a custom watercooling loop. Since I am designing my own case I have total freedom when it comes to radiator space and placement. Anyway, I'm assuming I'd need at least a dual 120mm rad per component for overclocking headroom. I was thinking I could get additional radiator space so that I could lower the fan speed and thus make the whole computer quieter. Therefore, I'm wondering at what point would more radiator space become useless, or even detrimental? How much radiator space would you recommend?

 

note: I have no way of knowing what the TDP of the flagship Pascal GPU's will be, But i'm working off the assumption that it will be comparable to 980ti's.

more radiators would let you turn down the fans, but THICKER radiators would actually be better

You could almost run passive with enough radiators but I wouldn't do that at full load. For what you're doing I'd use 2 480 rads.
