FD Define R5 with CM 140XL fan upgrade options

[FractalEvolution]

Fractal Design Define R5 with Cooler Master Nepton 140XL:

Front intake: Fractal Design GP-14 X2 (low RPM)
Rear exhaust: Fractal Design GP-14 (low RPM)
Heatsink: front mount push only with Noctua NF-F12 PWM just under the optical bay (middle hdd bay is removed)

This setup is very silent, almost dead silent but I can hear bearing of GP-14s so time for an upgrade that can cool SLI GPUs.

My idea is to get 2x Silent Wings 3 (3-pin) for case but I don't know what to get for push-pull on 140XL and I hope you can help me. I am trying to stick to dark theme, F12 was leftover from CM 212X days and I use it now because stock CM JetFlos are standing up to their name, jets.

My other dilemma is about static pressure vs air flow fans: will best 140mm SP fan move air from the case as AF optimized fan?

p.s. Price is not on debate this time and only radiator I could fit and still like the looks is single 140mm in the front. I hear major coil whine from the pump @100% so maybe I get different brand soon keeping the same layout

What video cards are you going to SLI.

EVGA GTX 1070 SC AC3.0 installed, another one still unpacked. Thinking about this variations:

Front intake: be quiet! SilentWings 3 140 (3-pin) @100% 15.5db
Rear exhaust: be quiet! SilentWings 3 140 (3-pin) @100% 15.5db
Bottom intake: be quiet! SilentWings 3 120mm (3-pin) @100% 15.5db

Front intake: NF-P14s redux-900 @100% 13.2db
Rear exhaust: NF-P14s redux-900 @100% 13.2db
Bottom intake: NF-P14s redux-900 @100% 13.2db

Heatsink: Push-Pull PWM

Phanteks are your best bet for the heatsink
