Designing Custom Water System, Need Input.

post #1 of 6
Thread Starter 
Hiya forum... hows it going? That's good...

got a few questions for y'all. I'm designing a custom water cooling setup for a rig I'll be doing in time for LGA2011. firstly I've decided on two loops, a gpu loop and then a system loop (CPU, ram and mobo) and I've chosen to go with two different UV setups on each. I'm going with red for the gpu's and i have the choice of UV green or yellow for the main loop, i CAN go with UV blue but to retain Koolance's warranty, you can only use their coolants but I'm still interested in as to what the larger community has to say .

also, the gpu's are undecided as of yet. depending if any new cards come out around lga2011 (anyone know of any? ). considering all the fuss around the 590 and its overclocking setbacks (almost no headroom thanks to nVidia) I've opted to either wait for new cards around lga2011 or go for 3 or 4 580's, most probably 3.

thirdly, the case I'll be using is the Lian-Li X2000F (being the sexy thing that it is an all ) and I've opted for two reservoirs, and 3x 420 Rad's (two for the gpu loop and one for the main). after some thinking and rough sketches, I've come to the conclusion the best place for the rad's to be mounted is on the back panel (or side panel... w/e). the reservoirs are 240mm tall so I'm thinking they might have to be placed outside of the case aswell, and if you haven't guessed by now the entire system is Koolance.

if i think of anything else I'll either edit this or add it in a separate post.

thanks in advance.

EDIT: Sorry... i should have clarified the rad's first lol, the rad's are 3 420's (or 3x140mm each rad however you would like to interpret it lol)

Personally, I would probably run dedicated CPU and put the GPUs, ram and chipset on the other loop.

Secondly, you'll prob be better off not using dyed coolant and using UV reactive tubing instead.


As got GPUs, wait and see what is out, my guess is we'll be looking at a 600 series by then and ATI might have grabbed the market by the balls once more ~ it's too early to say what will be good.

That also may be a little light on radiators, I would go for 2 rads for CPU chipset and RAM definitely.

and 4 580s would kick out a phenomenal amount of heat, I'd be looking at a triple rad personally.

There's no way he needs 2 420 rads for just a cpu, chipset, and memory. The absolute maximum amount of heat that could ever put out would be 200 something (which is probably an exaggeration) and a single 420 can EASILY cool that with slow fans.

Stick with using the 2 420s for those gpus as that is more than enough rad for them as well.

Like Crabid said, uv coolant will eventually gunk up your blocks. If you plan on replacing the coolant every couple of months then you're fine, otherwise go with distilled water + kill coil with uv tubing.

He said 3 x 140mm rads, not 420, I wouldn't ever suggest having 2 massive rads like that for CPU chipset and memory, 280mm of radiator on the other hand... Probably needed.

Good to point it out though, 3x140mm rads could be interpreted two ways, best get feedback from the OP to clarify that point.

Don't bother with coolant. Just pick whichever color tubing you want the loop to be. The colored coolant will gunk up your blocks eventually and decrease performance. Unless you change the coolant every 2 months and use an inline filter from koolance you will get gunking.

Give us a price range and helping you design a loop will be much easier. You can go cheap or you can go all out. To cool all of that which stated above you're looking at a minimum of $1000, but a truly quality loop for a tri/quad/4way sli setup will run you around $1700+. I went all out on mine and it racked up to around $2300.

Since that system will put out some major heat you should look at getting a different case, such as ones by mountain mods, danger den, or case labs, so that you can fit all of your radiators internally. That lianli case is awful for watercooling. It's just not setup properly.

Koolance makes great blocks, but they don't make the best radiators. Check out HW labs for rads designed for super low rpm fans as well as high rpm fans. XSPC makes great rads for midspeed fans.

You will want to wait for kepler to come out before you buy gpus. They will be a good bit faster than the fermi cards. I will definitely be upgrading to 4 of whatever nvidia's top of the line card is as well as dual socket 2011 xeons. There's no way I'd try to shove anything like that into that case with such minimal potential for cooling. Rule of thumb use 1x 140mm rad area for every high end gpu and a minimum of 240 rad area for each cpu. That way no matter which rads you decide on you'll have decent temps and it'll make watercooling worth it.

As for dual loops... dual loops are only a good idea if you do not have a large amount of heat dissipation ability. Gpus will see better temps on a single loop while the cpu will see slightly worse when at TDP. Gaming you're generally better off with a single loop. I've done both setups with my sigrig and a single loop ended up fitting my needs much better (I fold 24/7 and occasionally game).


If you need any ideas for higher end wc check out the worklog in my sig.

Sorry to the late reply, we lost the net for some strange reason due to an error on our ISP's side.

Sorry about the confusion with the rad's, they are 420's. Edited accordingly.

I guess I can change the coolant to the high-performance clear one and the tubing from clear UV to red UV for the gpu loop and blue UV for the system with tubing wrap for each one respectively.

Price range is pretty much whatever it costs... lol im going for a completely modular water cooling system [as in using koolance quick-disconnects for the cpu, gpu's and rads(or reservoirs, need to do some more sketches and toy with some layout ideas)], and am even debating just building a case for the hell of it lol.

i came up with the idea to partially mod the front of the lian-li case so that the fans will sit on the front behind the removable faceplate/shield, and the radiator for the system loop would go inside where the front 3 140mm fans currently sit. another one would be mounted outside on the rear covering the rear 140mm fans, modification to the case would be required to do that but not that much. the pumps would sit down where the bottom HDD cage sits, i cant remember if that is the removable one but I'll remove it hahaha. the last rad could either be mounted on the top or on the right side panel(the back one) down the bottom.

which would you recommend? im looking at either the SR-1 420 or the GT EXTREME 420... if i end up building my own case, i'll get the 560 variant of which ever one.

i heard about this "kepler" but i hadnt had time to look into it, i might do that soon but seeing as there is a new one coming out i'll definately be getting those. no sense in mixing old tech with new tech lol.

allow me to explain the loops a little more thoroughly just so we are on the same track lol. the two loops is for each area (i.e the GPU's have their own loop, and the rest, system, has its loop. thus the reason for 2 res's and 2 pumps). i was originally going to have the coolant split from the pump into each GPU but then i remembered about gravity and water following the least resistance, it probs would cause issues with pressure and flow rates. could one possible fix be to use the pump reservoir bases? as they have two outlets and one inlet i believe... just an idea.
