My WC Layout

[Istari1]

Ok, so heres the layout I have planned (tubing wise) for my WC setup, possibly. At the moment I dont have the NB block so that part is still underway. The thick lines are 1/2" silicon tubing, the thin lines are 3/8" silicon tubing. The pump is 500 GPH and the rad is a 78 Chevy heatercore. Now do you all think I should just go ahead and get a 1/2" barbed NB WB and run it in series? I am hoping that this setup will cause more water to go through the CPU WB then NB WB since the tubing is larger in that direction (and the CPU WB has larger channels). Any thoughts? Thanks all.

Almost forgot. Was also thinking of maybe getting a GPU instead of (also) the NB Wb and running it aong the 3/8" circuit.

Here how I would place yours. Water on the northbridge is rather extreme, so I placed it to be last. In yours, you seem to be using a y-splitter so the water splits 50/50. IMHO it's not worth it, the northbridge doesn't put out as much heat as the CPU, so the water coming out of the block will do fine for it. Ignore my MS Paint skills as well.

I wasnt so much worried about the added heat from the NB block, as the fact that the NB blocks are small and have small channels so it would restrict the flow alot. You think having it in series would still be a better layout as far as flow is concered? And what about GPU cooling, what this splitting method be better suited if I was cooling my GF3 not the NB.? Thanks for all the help.

Your going to need a very strong pump to go through 3 blocks if you add a GPU block. The block isn't only restricting the flow, it's also the lenght of the tubing. My previous pump pumped 211gph, with 4ft of tubing it dropped to 60gph which is horrible.

60 GPH isnt really that bad I wouldnt think. Most of the tests I've seen have systems running anywhere from .5-2 GPM thats only 30 GPH-120 GPH. I figure I want at most 120 GPH really. Its a hard balancing act cause fatser movement through the WB is good, but slower movement through the radiator is good also...shrug.

I'll tell you, it all adds up. I just added a NB block made from a 2"x2"x1/4" piece of copper with a copper pipe end cap cut down to 1/2" high. I sweated two 1/2" barbs into it and placed it after my Gemini Spiral Block in the return path to the pump. The NB on the ASUS A7V333 runs really hot compared to my ABIT KT7A and IWILL KK266+. My core temperature rose 3C. The addition only involved an additional 8 inches of tubing. I went to great lengths to insure the flow resistance through the NB cooler was less than the CPU block, which has 3/8" barbs, but apparently the whole endeavor made my setup fall outside the "sweet zone". I figure I need to get a more powerful pump, though I never suspected such a small change in architecture would impact my core temperature so much.

3/8 has about 56% of the CSA of 1/2 inch tubing, so if you split it off with 3/8 you'll get around a third of the flow going through the northbridge and 2/3 through the CPU. . . . . . . theoretically. You could put a valve in the northbridge line to tune it to keep it "cool enough" and let your CPU take all it can get.
