You will be more than fine with that setup. You would be perfectly fine with just the 360mm or 420mm alone for your setup.. but this case is just asking to be filled with rads. That's why I did a 420mm, 360mm, and 240mm for my 6700k and 980 Ti. Wayy overkill, but it's better to put more rads than you need rather than less!
Yeah, I know.
My current is enough to cool everything (360 + 140.1). My cpu is dumping serious amounts of heat into the loop though. I have no way to measure exactly but I'm pretty sure it goes over 200W easy.
But, I want the loop to be rather silent. There is a huge difference in radiator heat dissipation comparing 800-1000 vs 1600-1800 rpm fans. So is the noise.

I also highly recommend using a 7mm decoupler between fans and bottom of case for the bottom mounted rads for better airflow and minimize vibration. I use two 120mm fans blowing over dual GPUs mounted on the HDD cage instead of a res there for much better GPU VRM and Mobo Chipset temps.
So you think I won't manage to fit my res/pump combo next to my gpu? I am perfectly fine modding the reservoir mount a bit.
I can place the pump in front of the gpu (attached to the backpanel of the case) but that will probably force me to use separate pump and reservoir, right?
I will grab some decouplers for the radiator, no problem. Those are cheap.
Do you really need extra airflow over GPUs that are watercooled? That sounds like bs to me. My temps are awesome on the card and will only be better with more rad space. VRMs on my card with a heavy overclock are like 45-50c compared to the 100c (on stock!) with the original air cooler.
What does concern me though, is the cpu socket temp.
I modded my current case to be able to place a fan behind the motherboard blowing fresh air to the back of the socket (lowering my cpu(socket) temp by 10-12c. It's a known thing on these Vishera (amd fx83x0 chips). I don't really feel like cutting up my Phanteks when I do get it.
