Custom Loop Thoughts

[mb67]

Hello one and all. I'm getting the necessary parts together for my first ever custom loop computer, and I wanted some thoughts on a loop layout.

Any assistance would be greatly appreciated.

But first, a little background:

I wanted to be a little 'different' in that I bought a case that is not very well known here in the US - The Jonsbo UMX4. It's a rather small ATX case with two gorgeous tempered glass panels on it. The PSU sits up front with some room underneath for cables to stack or possible a small pump/res, which is what I want to do. Also, there is room for a pair of 120 fans at the bottom. Since the case is not in the EKWB configurator I used one that was close in specs and it gave me a 240 Rad up top, and a 120 Rad at the back. The CPU will be the Ryzen 7 1800X, the GPU's 2 x GTX 1080Ti's FE, on the ASUS Crosshair VI Hero X370 board.

I've already got the CPU/GPU's and the corresponding blocks, as well as the board and case, so I'm committed to doing this. I just need some help on the layout.

Two questions: 1) will the 120+240 Rads be enough? 2) will the following layout be sufficient?

This is the flow chart I came up with:

From the pump/res, to the GPU's, to the 120 Rad, to the CPU, to the 240 Rad, back to the pump/res.

Layout seems fine, but keep in mind the standard recommendation for radiator space is typically 120mm per unit + 120mm. So you're actually 120mm short. Expect those 1080 Ti to run hotter than normal, and your fans won't be able to run at slow speeds with that setup.

The question is: Do you really need 2 x 1080 Ti? Could you possibly make do with one? If not get a bigger case where you can have way more radiator space.

Would a 240 on the bottom instead of the 120 at the back be a better fit then, as in having a 240 top and bottom?

EDIT

I'm okay with higher fan speeds, as I use headphones all of the time.

1) 120+240 rads will cool that hardware but the fans will go berserk which kinda breaks the point of water cooling - silence, and the temps will be high. I would recommend you putting another 240 at the bottom. Measure the space between mbo and top/bottom of the case, and go with the thickest radiator you can. From the dimensions of the case i think EKWB PE 240 with one set of fans will fit.

2) Layout is fine just add another rad at the bottom.

Thanks for the input!

Are you dead set on having 2 GPU's? That is a lot of heat generation for such a small system. One GPU and it would work great.

It's already been done. I sold my 980Ti's and got the 1080ti's for under $500/each.

My 'sensibility chain' has been severed when it comes to computer parts.

The rads will be fine for cooling, use a decent pump set a little higher rather than upping your fan speeds too much. flow rate is as, if not, more effective at keeping the temps down than upping the fans.
