Swiftech h240x2 loop

[jerzer]

Hi there,

I'm currently using a Swiftech h240x2 to cool my i7 6850k. I also have two 1080's air cooled, for now. I plan to buy two more cards by the end of the year. It's a workstation for 3D GPU rendering by the way.

I have few questions tho.

1. Will my current h240x2 pump will be 'strong' enough to pump so much water for 4x GPUs + CPU, or should I just get an additional standalone pump?

2. Radiatos. Will this be enough? Otherwise I'll need a bigger case. The following is what I can fit:

• 1x Swiftech h240x2 (140mm x 293 mm) I already have this one.
• 1x 180 dual (180mm x 400mm)
• 1x 120 dual (120mm x 280mm)

Thanks in advance!!

I'm wondering if Aigomorla would recommend dual pumps for that sort of cooling.

I'd also think that you definitely need some sort of water-cooling for that rig, and 4x GPUs almost seems beyond ambitious. That adds a lot of extra hose connections to the equation. You didn't mention what case you're using, but that's one in a nexus of choices you have to make if you want to fit that many radiators into the box. Personally, I just decided to limit myself to a midtower case. And if I can't put the entire cooling system inside the case, I don't want to do it.

I was looking at the H240 x2 as an option for the last six months. I think if you plan on fitting 4 dGPUs in there, you'd do better with a "true" custom-water arrangement. I'd think you'd want dual pumps in that arrangement. I'm guessing you could add an extra pump with that AiO and the extra radiators. But why not just pick the parts instead of beginning on a foundation of that cooler?

You should be pretty well off with three dual slot radiators. I would recommend going the dual pump route however, even if not necessary for flow rate, simply for redundancy if you have a cpu and multiple GPUs depending upon it.

I'll tell you what I did that was inexpensive, worked well, and was easy to implement in my 3930K box. I added an XSPC Ion pump/reservoir combo (along with an additional radiator) to my H240-X. The Ion itself wouldn't make the best pump for anything but a small loop, but it did give a nice little boost to the Swiftech's flowrate while working in tandem. Not MCP35X2 levels, but a noticable increase, and enough flow on its own that the components would easily survive a failure of the main Swiftech pump. It's also attractive, compact, and comes with it's own handy mounting brackets.

Thanks guys. Sounds like a good idea to have two pumps in case one dies. That XSPC looks very nice indeed, I'll consider it. Thanks again!

do not mix pumps...

if your going to pair up pumps it is best to pair them identically because mixing pumps can potentially wear out the weaker pump faster due to the stronger pump forcing the weaker pump to do work it was designed for.

So if you are going to dump 2800 dollars on gpu's i would not bat twice at investing 200 dollars for something like this where it was deisgned to be run in tandem for both redundancy and greater flow.

Also it is safe to say you will need at least 1x120mm radiator surface area per gpu, and per cpu for moderate noise levels and acceptable watercooling temps.
If you want less noise, 2x120 will allow you to get away with fairly low noise at again, acceptable cooling temps, if you pair it with the proper radiator. (low FPI thick core radiator.)

So looking at 4gpus + 1 cpu = 5x120 for bare minimum...
And 10x120 for ideal plus..... which is a LOT.... so i think u could probably be fine and get away somewhere in the middle like at 8x120.

The H240 is not what i consider a low FPI thick core radiator.
I would recommend you to look at XSPC RX series.

Also my values come from assumption that everything will be under load... and you will have what is called a temperature gradient inside your loop, from the 4 gpu's.
Meaning portions of your loop will be hotter then others due to you having more then 350W of heat source on one side.

Thank you aigomorla for sharing your knowledge. Good to know it's not good to mix differnt pumps. I'll go ahead and do a full custom loop. Isn't gonna be cheap, but hopefully performance will be worth it! Thanks again!
