I plan to build a new WC setup around a CM Stacker. The systems specs will be as follows:

AMD 3700+ San Diego
Asus A8N-SLI Premium
2xXFX 7800GTX
4x51MB Crucial Ballistix

All of this will surely be overclocked, so there will be alot of heat in this loop. Below is a picture of the setup I had in mind, but my biggest fear is the pump won't be able to power through it all.

setupjpg.jpg


CPU Block = Swiftech Storm G4
GPU = 2x Maze4 Low Profile
Bottem Rad = Black Ice Micro II (spare ive got lying around)
Front Rad = Black Ice Xtreme II
Res = Any 5.25 res
Pump = Laing D5

The flow should work fine, thats my issue. What I am wondering though, is if that pump will be able to get through all that. I had concidered an Iwaki pump, but I would rather not get one. Its not for the money, as much as it is the appearnce, and the work to get the right fittings. I woudl rather have a pump made to WC. Thats the same reason I am going with the rads over a heatercore...I don't want the hassle of getting the right fittings, and I am a stickler about the comestic look of my PC. With it costing as much as it will, i want it to look nice. If that pump wouldn't be up to that full loop, would it work to just use two of them? Shurly the stackers got enough room for both, but I don't want to get two if its just going to be overkill.

Thoughts?

EDIT: I also had a second idea, but space could be tough. Being that I may need two pumps anyways, and a 2nd res would be nothing, would it be smarter to create two seperate loops? The other problem here is that I am now down to like 2 5.25 bays if I do that, and being that I have two CD-Roms, 2 HD's, and a floppy (can do without) to mount, that woudlnt work. Here is the idea I had though. I have seen people stack the 3 to 4 HD cage at the bottem of the case, and set the pump on top of it. How would it work to have 3.15 res's in that? Would it mess with flow to have the res so low/?
 
That pump will handle it well. The Laing D5/MCP655 is a very powerful pump. You don't need the second rad (the BIM) imho. And without you won't have to do anything to your case that requires tools.

I woudlnt need tools either way. The bottem of the stacker is vented. Thats the only reason I had concidered it.
 
as usual: the BIP2 is a bit cheaper, and usually perfroms better than the BIX2 if you are using sane fans. any fans lower than 40 db will probably do better with the BIP than the BIX.

you don't need the micro, but i understand wanting to use it, if you have it already. in most cases, mounting it at the back would make more sense, but since the stacker uses 120mm fans in back.....oh well.

you could use a Y fitting to split the flow between the two identical video card blocks to get a little added performance due to decreased flow restriction......but it probably won't make enough of a difference to matter.

res should always be as close in the loop to the pump inlet as you can manage, for best pump opperation. you might want to re-order things a bit.
 
Having the outlet of the pump going into the res is not a good idea. the res should be hooked to the inlet of the pump...

I thought I may have had it backwards. I wasn;t sure which way that pump went. Thanks for clearing it up.

DFI Daishi...do you have links to a comparison between the BIX2 and BIP2? I plan to use 4x120mm panaflo's, so they would be low speed and quite, but I figured being push/pull, they would have no problem dealing with the added thickness of the rad. Knowing what I plan to use, what would you suggest?

Now, on the BIM2, you say I dont need it, but would it help? Obviosly, no ploint in having it if it wont help temps a bit, but even its its 1-2C cooler, since ive got it, may as well use it.

rad testing: http://www.overclockers.com/topiclist/index31.asp#WATER COOLING
i know, i know, it's overclockers.com. that's what i said at first as well. they are thorough reviews with good test equipement all the same.

i don't like the way that they do the relationship between fans and rads, but there should be plenty of info on there for you.

what it all boils down to is that, using the BIP2 rad, you can get better performance than the BIX 2 through the 20-40 db range, assuming good quality fans on both rads.

single layer fans generating a given airflow do it more quietly than double stacked fans. you should only really consider double stacking if noise frequency is more important to you than noise intensity or if you are at the highest level of performance that a single layer of fans will give you.

as for numbers with the addition of the micro......i don't know. someone like cathar or one of the other people who knows the equations that model this stuff could probably tell you, but i can't. gain on the radiating surface, loss on the coolant flow rate......i don't know which will matter more in your loop.
 
Here are two more layouts, based on the pumps flow that I got wrong before. Someone chime in on which is better. They are a bit messier...but I am not sure what else I can do, unless that pump would still function fine rotated upright. Anyone try?

Wow! I didn't know that. How big is the vent? Do you think it could accomadate a 2x120mm rad?

the pump will operate upright

Russ... I am not sure exactly how big the venting is on the bottem of the case, as I do not have it yet, but I don't belive it would be big enough to accomodate a 2x120mm core without a small bit of modding. I have seen it done, but if I recall some cutting was done.

DFI Daishi... Doing some thinking, I have decided to ditch the BIM2. It will probably restrict flow more than it will help cooling. The 2x120mm should do fine what I want it to do. On that link you gave me, looks nice, but I am not sure if I will go with it, I have to do some pricing. I do not like the reserviors that swiftech makes. I prefer the acrylic ones dangerden sells. I currently have the swiftech res that is made to accomate the MCP350 pump, and while the space savingness is great, I just dont like the res. That is one of the things I will be selling to help pay for this new project. Also, I woudl probably rather have the BIM2 over that radatior. They had quite a price drop over at dangerdenstore, so it would probably be cheaper to just get it all seperate anyways.
