water cooling

I am thinking about watercooling for my next sytem, however i definitely dont want the big green tubes all over the place that everyone seems so fond of. I tend to think in terms of straightlines and right angles and am wondering if it would be such a significant problem to route all of the tubes that way instead of the tube going from point A to B mess.

Also, has anyone ever used perhaps copper tubing, or some other rigid tubing for their watercooling system and how does that fare as compared to the flexible tube?
 
Look at this one for ideas. LINK

From what I've read, right angles will impede the flow unless you have the pump and the know-how. Granted I've never tried it.
 
thanks for the link that is fairly close to what i am looking to do. I like the cooling and sound benefits of water cooling, but never have been a fan of how most people rig them up...

i will have to do some research into how much flow will be lost given pipe diameter, water flow rate and the angles it is encountering... thank god for calculus and differential equations non?
 
You don't need calculus 😛

Google has it 😉 Look around for flow rate drops with 90 degree angles.
Why compromise with pipe diameter?

well yes that would save time, but remove the massive nerd boost i would get from calculating it myself... but being inherently lazy.... i think i ill indeed turn to google
 
Well if you want the best flow rate then I wouldn't do the whole 90 degree angle thing. Just use distilled water in clear tubing. That clean enough for ya? Just make sure that all the blocks are made of same metal since there probably won't be an addative in there.

If you want more neatness, go for 3/8in. tubing, but I'd just stick with 1/2in.
 
hmm, its less an issue of not wanting big green tubes everywhere (which i dont) and more an issure of how i dont want it to be cluttered almost looking like an aftertought... this is an expensive piece of technology and I want it to look as such
 
i thinkn you are missing part of my point... the first point was that i didnt want the big green tubes and you have certainly addressed that, however i also mention that i am curious if there would be a significant problem with using straights and 90 degree turns instead of just tubes going from A to B. It would be more routed and seem more like there was actual effort, planning and consideration put into it.

Well to put it simple, the flow rate wouldn't be as good. And I think it would look better with just the tubing than the 90 degree angles and stuff.

(plus alot of the stuff is just standard with 1/2in. ID barbs., makes your life easier.)

But either way you go, the final choice is up to you. I say don't get the 90 degree angle things, but hey it's your WC loop. I can suggest a few other coponents if you want, as I just ordered my WC stuff too.

Edit: Link to my Watercooling setup (incase you cared)
 
I took a look at your setup and realize i have some more research do to about wather cooling in general, for instance i was under the impression that it would be ill advised to run the tubing from the cpu to the gpu simply because then you are running heated water across a hot surface and not getting the same benefit as running cool water across the surface, but the only real way to do it my way would be with multiple pumps and rads... or even several small loops that dont even connect to each other... again, i will have to put more planning into this, but thanks for your advice thus far

Loop order really doesn't matter all that much, just (out of common sense) don't put the Storm last (in my case). The water coming out of the block isn't really all the hot at all. Most likly it couldn't have gone up more than 2 degrees at most and thats probably pushing it.

My setup is a pretty expensive and sort of top of the line. I don't think your running SLI so I doubt you'd need such a powerful rad as mine, and other components as well.

You can PM me if you want, but I'm not an expert on WC.

(XS seems to be down or something? Was gonna post some links, but I guess I'll PM you later).

water flow will always be restricted at 90 degree's. The most common and somewhat fatal mistake in water cooling is when the tube kinks and the water is cut off. That is why there are kink gaurds to prevent the tube from bending a full 90.

I would have to say depending on the pump your using and how many 90 degree elbow joints, u should be fine. The more 90 degree elbows u use, the stronger pump your going to need.

Also, as wiz said, the water coming out of the block isnt very hot because if u concider the fact that water is being pushed at nearly 75gph, on decient pumps, the water doesnt stay on the block long enough for it to heat up drastically. Yet since u got water being pushed though consistantly, the block is cooled. However, i did read when ur doing a SLI cooling on a WC, u should use Y spliters.

Just a little advice, if ur really anal and want maximum cooling, u could always use a Y spliter. It would be something like this.

3 port Res. (outlet) -> radiator -> pump -> Y split one going to CPU the other going to GPU -> then have both exit to each inlet on your 3 port res.

Since some bay res's have 2 inlet ports and 1 outlet port, u could pull it off that way.

I hope this helps :]
 
it does indeed, thanks for all the advice thus far. When it comes time for me to build this thing (new machine for next school year) I'll definitely post some pics of the final product

Danger Den do a two bay res.

I think they do a few varients, with three ports, four ports and two ports.

Not sure how effective they are, but I imagine there are some reviews somewhere on the web.
 
If your looking for a 3 port res, go to PTS and get theirs (it's a swiftech I think) and it's the only Res. they sell.

The reason for multiple returns and exhausts on a res is to facilitate multiple loops in one machine. This isn't to say that there's no room for creativity, but it's good to know why things are the way they are. Y connectors and SLI rigs: TBH, I've never seen anyone suggest that two video blocks are best served by a Y connector. Using one would at best half the flow to each card, which wouldn't seem to be adviseable. Contemporay GPU blocks aren't usually impingment, but some come pretty close, like my NV78's. At worst, due to slight differences in the tubing runs, one card could end up being starved for flow.

If a less than cluttered look is desireable, I'd suggest keeping things linear.
 
Yeah, and you should also be prepared for the "cluttered" look that comes along the with external mount of that Iwaki. And let's no forget about the EMI field penalty associated with a pump of that stature.

exactly what i was going to say. Do not run the gpu blocks in parallel. flow will go the one iwth less resistance leavign the other block starved for flow.

watercooling doesn't necessarily= clutter
look at my setup

I can still easily work inside the machine
 
A Y splitter shouldn?t make any real world difference in flow rates. If the blocks are matched, the flow should be within a few percent of identical, as long as your pump is strong enough to keep a small amount of pressure in both lines. It?s easy to test, just hook it all up outside the case, turn on the pump and let each gpu block dump into an empty can. Check the water level in each can after 2 minutes; they will be close enough as not to matter.

like i said, a Y splitter shouldnt be used unless u have a fairly decient pump. And if ur going to loop more then just CPU, your going to need a strong pump. Personally all the rigg's ive seen with SLI used a Y splitter. My Rig however doesnt include the vid cards in the loop. I didnt want to drop in a big and bulky 2 fan radiator.
