Whats the best way to arrange 2 pumps in a full WC setup?

Inline or parallel?? 2 separated loops??

With a full wc setup, is better put my pumps inline or in parallel?

Have here the folow things to cool:

CPU - NB - GPU - SB - 2 VREGs each one with its blocks

2 Rads - 1x 120.3 and 1x 120.1
2 DD/CPS-MAG pumps


Is worth make 2 loops, 1 rad per loop or 1 big loop with inline or parallel pumps?

I have a thing defined at least, even in separated loops or in a big one, CPU and NB will be together in this order and GPU VREGs and SB also together in this order.

My firt idea was to do a big loop with the pumps in parallel (i already didi it). But i think flow is being affected in this case and im trying to figure out whats wrong. The loop is not yet running mouted, take a look at the pictures i did in mount test to cut the tubes:

The pumps

So, whats better to do with this bunch of options, which one will be the most efficient?


Thanks.

Make two different loops. 1 loop for CPU only (120.1) and the rest for chipsets, mosfets, video card and south &north bridge (120.3).

wow thats a maze of tubing. nice heater core there man.

the general concensus is to have one loop for cpu and one loop for everything else.

Ok, will try to do 2 loops, but which chip come first in 2nd loop? GPU or NB? Cos they are hottest on the loop.


And if i put the NB together CPU, but after CPU in the 1st loop, will affect NB?


Thanks in advices :)

I'm gonna have to disagree here. I'm saying go everything in serial. Your using CSP-Mags which are a bit weaker than most other ppl's pumps. Paired up, they produce reasonable pressure (somewhere ~6PSI, compared to ~3PSI single) which will help overcome the natural pressure drop in such a large system.

you surely know your pumps waterlogged

Well, will post the clean setup pic so u guys can edit and put the loops the way u like and repost it edited

Here is the way i edit with 2 loops
(the red line is the fillports, have to get another one to use 2 loops...)
sorry for the ugly edition :p

1- with CPU only on the 1st loop and rest of things on 2nd

2- with CPU and NB (After CPU) on the 1st and rest of things on 2nd

where did u get that colored tubing? It looks like a little small diameter wise. You should go with other colors than light blue and dark blue as well (assuming that color is the tubing and not from the fluid in them).

Did you paint the blocks black? Also, the rads will work better if you install fans on them. I hope you leak tested that setup first.

I wish . . .doing stats homework . . .worse on the brain than Jager

That is a pretty beefy setup there, Broseidon.

This is the way I'd set things up.

GueD'S, can you do me a favor and take pics of the insides of the pump backs. I have a few CSP's myself but they are the other style and the style you have may work better for a build I'm working on.

Watterlogged, the pumps are mounted with fluid now, and im lasy to do that atm, but in the c-systems web u can view this pump opened and its the same, no difference http://c-systems.ca/features.php

In your scheme above can u explain me few things? The CPU in the middle of the loop wont get hot?? And with 2 rads wouldnt be better to put one of them between some blocks, like before cpu?

like this

I agree with waterlogged. I like to have everything in one big serial loop.

Although, I like your last layout pic, with the radiators separating some of the blocks. I'd do that if it doesn't mean adding a lot of tubing.

The CPU might get a little warmer, how much is hard to say.

Your modification to my setup will work just about as well. Little bit of extra tubing in yours though.

I've already been through C-Systems site about 25 times looking for what I need to no avail.:( What I'm looking for is how they do the inlet from the same side as the outlet. The pumps I have are back inlet models.

Next time you pull the system apart, if you could, it would be greatly appreciated. :up:

Oh, understood, when i dismount the crazy mess i did surely will take the pic for u. Just wait a couple of days. Will remake the loop here, and then I'll be able to take that pic ;)

I'd combine the loops only because 1x120MM rad sucks for the CPU.

Many thanks. :toast:

Bro you're going to need some mechanical worm-drive clamps or maybe PVC locking tube clamps at every single junction otherwise you are GUARANTEED to have leaks. With 2 pumps in series and large amounts of tubing + WB architecture pressure-drops in the way of fast-flowing water, you will have a TREMENDOUS back-pressure force working against the weakest links of your loops (the tubing).

U are refering to the 2 first pics? That was taken at the moment i finish cut tubes to test its arrangement, when i finish the setup surely that it will have clamps :) Now i redoing the setup.








Waterlogged, here the pics u wanted ;)

1,000,000 Thanks GueD's. :up:

I always wondered if they offset the hole like that.

Wow that's alot like what I want to do with my P5K Deluxe.

I realise that aesthetically or w/e it might be tidier to plumb as depicted above starting at the SB...but I don't see it.

To me the block to start with is CPU...then Chipset...then GPU.

It will make plumbing a bit gnarly...but as long as you follow Darth Beavis' Advice and use thicker lines you should be fine :D

To answer your original (titular) questions I think the best way to run pumps is one before the CPU and one after the CPU--this has been shown to drop temps--especially with restrictive CPU waterblocks.

What a set up...I am still trying to wrap my mind around spending as much in blocks as I would for the CPU/RAM.

Good luck: and be sure to run it in with the sys powered down first.

***good layout***:up:

I look at dual loops much the same was as I look at multi-rail PSU's. Inefficient.

One loop may even not even be utilizing half its capacity, while the other may be insufficient. I find that to be a bigger drawback than whatever flow difficulties you may have to overcome with a single loop, but having two pumps offers a lot to overcome any imbalances in your loop as far as restrictions go, and even better, using two adjustable MCP-655's makes it that much easier.

One single big, huge capacity loop is better IMHO.

I like this setup too, but, wont the vga get hotter staying at the end of the loop?? And if i change the path from second pump (the upper one in layout) to 120x1 rad, changing the water intake from bottom to top wont help the pump to push less water upwards? Cos if water goes from bottom to top through the rad there will be more water volume than if it goes up from tube and then goes down through rad to cpu... am i right?
And thanks for help :)

As you don't seem too new, you already know how the temperature evens itself out in a loop. Nature, etc. You may/should have learned that trying to arrange your loop for the lowest superficial temps at any given point in your loop, for that snap shot picture, may not be what you are seeking as a goal.

Whoah!

That was deep.

It must be Friday.

See yall next week!

Sorry, i didn't understood it, :( could you try to be more specific? Thanks.

Order of components in a loop makes no difference.

It's a closed loop. The pump works equally hard no matter what you do. As much water as it pushes out of it's outlet automatically comes back into it's inlet.

You're missing the fundamentals of watercooling. http://www.overclockers.com/articles1088/

ok... how's bout this?

http://i44.photobucket.com/albums/f9...g1970/blah.jpg

this way, the 120.3 handles the CPU, MOSFETS, then the 120.1 handles the VGA and NB/SB?

Nooo.... there is no "blah handles blah cos it goes to it after blah". Again... the order of components in a loop DOES NOT affect performance. It takes 261 watts of heatload to raise watertemps by 1 degree. Order in the loop is irrelevant.

dear lord thats a mess, please clean it up and make two inline loops, it will look a lot better :p:

Many thanks Marci, u gave me the most important informations, loved the link to the Myths about WC, will do a simple big loop, and finish the setup, when done will post pics of it. Cheers.

Thanks for everyone who help here :)

Made the tube setup here and forgot to take pics, when mounted and running i'll do it, but using the previously layout it was finished that way:

Looking at it in a 2D layout may have a weird look, but this was the best aesthetic and functional way in real.
