Radiator help

[CompMage]

Ok I'm going to be working with a Corsair 750D

I'm going to be cooling a Skylake board and chip, (When ever it's out) and 2x GTX 980 in a single loop.

I was leaning to 2x Black Ice Nemesis 280GTS® Ultra Stealth U-Flow Low Profile Radiator in a push pull with some high pressure fans. Not that concerned with that much noise, but the ability to tone them down when not gaming. Or go with a single 360GTX, but I would like the extra cooling off the CPU before the GPU or the ability to later change to a dual loop if temps or pressure just will not keep up.

Res > Pump > Rad > CPU > Mobo > Rad2 > GPU1 > GPU2 back to Res.

Going to be using all hard-lines because it is cleaner looking and helps with the head pressure (Not much but every tiny bit helps in longer loops).

I'm not quite sure what the question is, but if you're asking whether to go for a 280mm or 360mm rad for this setup, the latter is the very least I would do. Even two relatively cool 980s and a CPU (assume all OC'ed) will put out enough heat to get your loop decently hot with a single 360. It will work, and it'll be better than air cooling all around, but it's not going to be ideal.

Edit: missed the fact that the 280mm option was actually two of them. I would do that over the single 360mm if you can.

Watercooling the motherboard is pretty much pointless at this point, just adds extra resistance to the loop. Also don't feel like you need to have a rad between the cpu and gpu's, rad location in the loop doesn't matter. Design your loop to have it as short as possible.
