So I've never watercooled before. I've only just begun to OC my GPU, and I probably won't OC my CPU very much, as I only have the stock fan, but decent airflow, at least not until my next rig.

I'm still deciding on a case, or whether I will try to use my current Antec Eleven Hundred, mod it, or come up with a scratch build.

I know that venturing into watercooling is quite an expensive endevour. This will not occur in the next few weeks, or even the next few months, I plan to slowly accumulate all the parts I need for a good watercooled rig. So honestly the cost isn't really an issue.

I will probably be keeping most of my current parts, but I know of several things I will be upgrading.

I currently have:
Case - Antec Eleven Hundred (NOT the new illusion)
CPU - Core i5 3570k - keeping
MOBO - GIGABYTE GA-Z77-D3H LGA 1155 Intel Z77 - replacing
GPU - EVGA 01G-P3-1460-KR 560 (Fermi) - replacing
RAM - 32 GB (4x8GB) Corsair Vengence DDR3 1600 - keeping
PSU - Corsair Professional Gold AX 750

I plan to replace my 560 with a pair of 7950s or 7970s, once the price drops. Put them in crossfire, and OC the hell out of em, but since I want to do this, I must also keep them cool and I figured I'd also OC that CPU while I'm at it.

I guess my questions boil down to what brands are the best for each of the pieces of a water loop, pump, resevoirs, rad, and so on?
What sites for the US are the best for buying the parts?
Should I get a new case, stick with my Antec Eleven Hundred, mod it, or come up with a scratch build?

Edit: At this point I can't really give a "Best Answer" as I've two incredibly helpful people give me a ton of advice, so I don't want to choose between Jake Wenta or manofchalk. If anything this thread turned into more of a discussion than it was a question to begin with. Anyways, I wanted any would be readers of this thread to get an idea of what I came up with through my own research after being prompted and through the ideas and advice of much more experienced members of the community.

If you're looking for voltage and clock speed tips and tricks, this is not the thread for you. This was a lot of theoretical water cooling discussion.

Unfortunately the Antec Eleven Hundred is not at all built for custom water cooling in mind, as there is only 'stock' space for a dual 120mm radiator on the side window, or if you want to remove the hdd cage, you can use the front port as a 2nd dual 120mm radiator mounting point.

Several other cases were discussed that are better for custom water cooling loops, Corsair 900D, or 800D, Coolermaster HAF-Stacker, Phanteks Enthoo Primo, Caselabs, or Mountain Mods. Or keeping whatever current case you have, and buying a cheap generic case and gutting it, in order to mod it with all your needed Radiators for a "rad-box"

I've actually decided that I'd like to design a scratch desk build, in the same vein as the L3P Razer Desk or the Cross by Red Harbringer. At some point there may be a build log for it, but honestly I wouldn't hold your breath for too long, as it's pretty much a pipe dream. I've also had a 2nd idea that I've drawn up, a full size tower, trying to correct all the issues I had with other cases, with an aesthetic I like.

I'll be going with as high CFM fans I can get while sticking with low RPM for low noise. These will be used for rad fans for push or pull configurations. Probably from Corsair, Noctua, Cougar, Phantek, or Xigametek. As I already have some Cougars, I may continue the theme, but we shall see. I will be trying for a 'Positive Pressure' build, meaning slightly more intake CFM as opposed to venting CFM, as that will limit the amount of dust and cat hair that can enter my system. Along with a strong recommendation for dust filters and keeping the system up off the floor, particularly carpeted floor.

From what I read, a D5 water pump, specifically the Swiftech MCP655 with variable speed is the best option for a water pump. But keep in mind that pump without a conversion top has 1/2" barbs or G1/4" threading.

Tubing seems to be very much a personal preference, color, wall thickness, material type and the like are all up to each person, though some tubing has a higher chance of stiffening and becoming brittle. I'll likely go with PrimoChill PrimoFlex Advanced LRT 1/2" ID 3/4" OD, color tbd, distilled water and a biocide on the recommendation of Linus from LinusTechTips

Solid Copper CPU blocks keep it the coolest. The Koolance 380i is supposed the best, but the contributors both seem to like the XSPC Raystorm

No real discussion about radiators has occurred beyond copper ones are good, but expensive.

No talks about reservoirs.

No talks about thermal pastes

GPU Water Blocks are very specific to each card, and there could be variations from the reference card, which can result in one block not fitting if you aren't careful.

Choosing between compression fittings and barbed fittings is all personal preference, as they do the same work, but compression fittings are considered a better aesthetic, but cost a bit more.

General brands to look at when looking into water cooling are XSPC, Swiftech, EK, Phobya, Heatkiller, and Alphacool.

US distribution sites to take a look at are FrozenCPU or PerformancePCs

I also like how my edit is longer than my original post.
 
Solution


Only difference is how they mount. You have to read what they fit for fittings.
For Example:
http://www.frozencpu.com/products/21271/ex-blc-1530/EK_ASUS_GeForce_780_GTX_DCII_VGA_Liquid_Cooling_Block_-_Acetal_Nickel_EK-FC780_GTX_DCII_-_AcetalNickel.html?tl=g30c311s1996
It says "G1/4" threaded fittings can be used on both sides of the FC terminal. Flow orientation doesn't matter and is thus not prescribed."

They have these for two+ GPU's:
http://www.frozencpu.com/cat/l3/g30/c101/s873/list/p1/Liquid_Cooling-Fittings-Accessories-SLI_Connectors-Page1.html
 
Gotcha, I'll keep an eye on the fittings and the spacing of the GPU blocks for when I get that connector.

Is there a maximum limit to the quantity of water that a single loop should contain. If a loop were to be large enough, would a second pump be a practical choice or is it better to make a second loop instead?
 


You can get an industrial pump, and run everything to your garage if you wanted :lol: It only depends on the power of your pump :)
If you get a second pump, then you can make a CPU (maybe VRM/RAM if you'd like) Loop.
And a GPU Loop.
 
Well it sounds like I can stick with a single D5 and be fine. I was just thinking that for the desk build, I'd want 2 rather large reservoirs (like 500mL each for the aesthetic and the more water the system has, the cooler the water stays) and wanted to be sure, that a single D5 could move all that liquid around.

I hadn't really thought about OCing my RAM or my chipset if even possible, in order for water cooling to really be necessary. Though I guess if I go through all this trouble, I might as well do it right, right?

I also added a large section to my opening post to try to summarize what all we discussed for future readers. I probably failed, and while it's unnecessary, it seemed like a good idea at the time.
 


You can put weak pumps with this:

for aesthetics. :)

With Watercooled RAM, you can probably go to 2800-3200 frequencies.
Chipset doesnt get too hot, but VRMs do. Which is what sned power to CPU. Cooler CPU means cooler VRM's and vice versa. People with watercooled systems, like me have VRM issues if we dont cool them with fans and stuff. CPU @58*C, VRM at 70*C (I have AMD)

And I'll take alook at your post.

As for reservoirs, you can't really go bad with reservoirs. They just hold the water-but people like the cylinders for the aesthetics.

As for thermal paste. If you want the best-theres a substance that'll void intel's warranty because it is so harsh that it will take the letter off the cpu. So Intel will know you didn't use their stock heatsink and thermal paste. The best according to many reviews is the Tuniq-TX4, but how you apply it is different. You must apply it to the whole cpu and not as a grain of rice.
I can not recall what that substance is-but I don't like it.
As for reservoirs. Copper will be the best. But the thicker the better, the wider the better, the longer the better. Different brands only change reliability really. The temp change between the best and worst of the same exact dimensions for radiators would probably be 2*C (same material of course, not aluminum vs copper).
You can also to a rad box or get an external radiator that can sit over 9 fans on each side :lol:
 
Back to the topic of making a the scratch build, where would I likely go to post up a build log, as now I'm getting really into this idea I have swirling around my head.

Is there are particular set of brands I should avoid at all costs for any parts of a water cooling loop?
 
Brands, not too sure-usually you want to worry more about mixing metals, fitting and tubing sizes, pump reviews and power...etc, tubing reviews(some kink others are poor quality material), radiator material and sizes. Just the basics.
It's not like an AMD nVidia, Intel thing. Where it's one has cuda and physx, one has opencl and steamprocessors. One has better overclocking and more cores, one has stronger cores...etc.
It's more along this lines of price-quality. (And material)

Although, some companies offer better coverage-and others longer warranties. Something to k eep an eye out for as well.
 
Bit-Tech has a pretty active modding community, including scratch build's. Of course, you can post build logs on any forum.

Not particularly, all of companies involved in water-cooling are fairly good. As you can imagine, there isnt much room for budget brands in this kind of area. Some companies do things better than others, but thats about it.
 


Well, what do you mean stick to? Like follow upon and read, or what?

There are a few threads here that can show you what people have done, as well as do's and don't, what works what doesn't, ...etc.

As I find them, I will post them for you. :)

I was more wondering if there was a particular subforum on tom's that is specific for modding/scratch builds/build logs. Looks like there are only a few threads dedicated to finished rigs, and such. Not really seeing many build logs though.

Looks like if I'm going to put this build log anywhere, I will post it here in the OC forum. Also I have a significantly more realistic scratch build idea, a tower similarly sized to the 900D, but with a better aesthetic, in my mind, and none of the things I don't like. but once I get a better set of sketches and a render done, I'll start up a thread with pictures and a part list.
 


Can't wait 😀

As for subforums, not that I know of.
