Intel Core i7-4770k - ASUS Maximus VI Formula Z87 - (2) EVGA GTX 780 Ti SLI - Corsair Obsidian 750D - Custom Liquid Cooling




Please note: Water-cooling loop diagram is a work-in-progress and subject to change

Hello everyone
thumb.gif


First off, I would like to thank OCN for all of the feedback and support you've given me over the past couple weeks. I recently sold my build (i7 950, GTX 480, 6GB DDR3) and have been out of the loop for a while in regards to keeping up-to-date with all of the hardware news as of late. The last time I was following hardware tech this closely was around the release of the GTX 480. Needless to say, it's been a while, and you kind folks at OCN never fail when it comes to helping out a fellow overclocker with his new build. Your feedback is greatly appreciated, and I intend to give back to the community with a detailed build-log of my new rig.

Please keep in mind that this will be my first attempt at setting up a custom water cooling loop... I sure do hope this goes well!

Purpose of this build: For gaming in 1440p and achieving high overclocks on the GPU and GPU's using a custom loop

Do you realize that having tubing come out the top of the reservoir will required an M2 to G1/4 adapter? also you would probably be better off buying the pump and res separately as they will cost less and that combo is more designed to have the inlet and outlet at the base of the res where the pump is. You also should be thinking/ planning for angled adapters, fill ports and drain ports to make the loop easier to use.

I recommend buying all your larger parts, eg rads, res, blocks. And planning out your loop before deciding on fittings.

Finally, have you decided on fans for the rads? best to look at gentle typhoons or a few others with very good static pressures. http://www.frozencpu.com/products/10323/fan-674/Scythe_Gentle_Typhoon_120mm_x_25mm_Fan_-_1850_RPM_D1225C12B5AP-15_Hot_Item_.html?tl=g36c15s60

Seeing as I have a few weeks or so until EK releases the GTX 780 Ti blocks, I do have some time to play with my water-cooling setup (I haven't ordered the parts yet, going to order them all at once)

I am aware that the XSPC Photon res contradicts the diagram I created in the initial post - Something that I am still deciding on. I do prefer the XSPC Photon reservoir over all of the others that I've seen, however the only issue is the M20 to G1/4" adapter installed will not allow me to fill the reservoir from the top... I'm thinking of using a Y-splitter and having one inlet port and the other as a fill port.

However, as you said, I am considering ordering my larger parts first to see how they would fit in my build.

. I am thinking of going for the photon 170 myself as it is glass instead of acrylic which is great when using coloured coolants as it doesn't stain. But the combo is not really the way to go, plus I don't really like how it looks IMO.

Which pump would you use with the Photon 170, and how would you go about setting them up together? For example, would you use a small piece of tubing, a male to male adapter, etc.? I am totally open to feedback

Well my plan is almost the same as yours except for the difference in rad placement and an extra GPU block in yours. I'm going to have a swiftech MCP665 D5 pump at the bottom of everything, have the photon turned upside down so the three holes are at the top and the fill port now links directly to the pump with tubing. For you the pump must flow first to the 280mm rad at the front then to the blocks etc etc... since the water must come down onto the pump rather than try to pump the water up the res, which most likely will stress or run risk of running the pump dry.
This will allow you to use the extra holes on the res as fillports.

I would change your loop order as the way it is now you would have the hot water from your gpus blasting your cpu. Arrange your loop so that the hot water from your gpus will hit a rad before going to any other component.

Subbed man!
Also yeah what i've been told/learned is that loop order doesnt matter as long as the pump is below the reservoir so it will never ever run dry, just look out for that.
Other than that, make it look as clean as possible with not so much tubing and it'll be done

Well as a past proud owner of GTX 480 sli water cooled (which i believe was rated at 250 watt each same as GTX 780ti) I can tell you for a fact that I had to get a 5000 btu a/c window unit for use in the summertime because my room got so hot while gaming.
I had the hot water from my video cards going to a 3x120mm rad just like the op (not same rad but same size) and let me tell you the air was hot coming off the radiator ( I believe I was using 2000 rpm fans also). I would not want that hot water hitting my cpu.
Well he can install his loop as drawn and if he finds that he has high cpu temps he can replumb the loop as tubing is very cheap.
Good luck op with your awesome build I look forward to seeing it completed.

Also, please note that the water-cooling diagram in the original post is subject to change. I am taking into consideration almost everything that everyone in this topic has mentioned. For example, using a 2x120mm rad instead of a 2x140mm, and placing it on the bottom (Thanks IBIubbleTea) and having the loop go from RAD -> GPU -> GPU -> RAD -> CPU -> RAD (Thanks Master_Shake and division2)

I will begin assembling the build tonight once I get home from work. This is going to be a long day at the office...

No problem, Im planning on doing what your doing but this is my planning build.
http://ca.pcpartpicker.com/p/1Z2eA

Using the same full copper rad as you like 3x120 and 2x120 on bottom, for the bottom, idk if the rad would fit because it sticks out a bit near the end...

To be honest, you'll notice that I ordered an AX860i for this build. I plan on swapping this out soon with an AX1200i just to be safe, considering these full fledged GK110 GPU's when over-volted draw a significant amount of power.

On stock with no overclocking? You should be fine with a quality 850W or 860W PSU.

What about mild over clocking? Or just over clocking of the CPU only? Im going to be doing a micro atx build with either dual GTX 780's or Dual 290x's with a 4770k, with a water cooled system sporting a 35x pump,2 small radiators and couple of SSD's and regular hd's I would like to grab the AX860i, but not sure if its enough for the setup. Kind of have a $200 budget for the PSU and really like the COrsair AX i units. So my build will be very similar to yours, just in a smaller form factor.
