Single or Dual loop for big watercooling and overclocking project

[TheRealBeandip]

Im going to be doing a full rebuild of my system and cant decide on going single or dual loop. I will be cooling two Titan X graphics cards, both of which will be overclocked. And an i7-5930k that will be overclocked.

For cooling I will be using 2 480mm radiators. (1 XPC AX480 and another 60mm thick radiator which I havent chosen, both in push/pull) and 2 240mm radiators (XSPC AX240)

For pumps I will be using 1 or 2 (depending) XSPC Photon 170mm D5vario

1/2" ID 3/4" OD Primochill primoflex tubing.

Im using a Phanteks Enthoo Primo for the case.

Should I split into dual loops and how should I divide the radatiors?

I was thinking the advantage of a dual loop solution would be isolating the CPU and GPU temps from eachother, the downside is that if a radiator is more than enough for one part, I am losing some of its heat dissipation potential by not including it in the loop with the other parts.

I will be using Noctua NF-F12 ippc 2000rp pwm fans

Dual loops, mainly because your cards naturally run hotter anyway. Keeping that heat away from your cpu would be a priority for me.

Thats what I was thinking. How should I split up the radiators then?

I may include the motherboard on the CPU loop if I have VRM temp issues while overclocking

Im using an ASUS Sabertooth X99 motherboard.

its a lot of radiator for what id consider... but something along the lines of a 480 for each gpu, then the 2 240's and 60 for the cpu and vrm...

although considering most people only use one radiator for a cpu... you probably have a lot of waste that way

it would be less pretty, but probably more effective to add one of the 240's or the 60 to the gpu loop too.

i would have thought a 240 and 60 would be enough for the cpu loop, but that depends on how severely you will try to push it, most of the time these days you hit a voltage wall before you hit the thermal wall.

up to you how you think that will go, what boundaries you are willing to cross 😛 i would hate to brick a chip just to prove my cooling works xD

There is no 60mm rad. Its a 60mm thick 480mm rad.

I think ill probably do 1 480 and 2 240s for the GPUs. Then a 480 for the CPU and VRM.

Its overkill but i really want to push these. Ive looked a lot into haswell-e overclocking and people are seeing some pretty high temps at 1.3 vcore. Im aiming for 4.6-4.8ghz on the CPU. And a custom BIOS on the GPU so i can unlock the voltages and shoot for 1.6ghz. I can get them to a stable 1.4 on stock BIOS.

The extra rads also gives me the ability to add more graphics cards in the future.

ah :3 i misread yea sounds like a plan.
