ive just been thinking... ive got my stuff coming wed, heres what i have coming to give you guys some info

BIX
RBX block
maze4 gpu
hydor l30
typhoon quad res
dual evercool aluminum fans in push/pull on the BIX
tygon tubes

my question... what order should i set this up in? ive always heard:

pump>rad>res>cpu>gpu>pump

however, ive been thinking, since the rbx has dual outlets, i could possibly eliminate some of the flow restriction of a y fitting by not rejoining the outlets but doing this order

pump>rad>cpu>res>gpu>pump

to me it seems like since the typhoon can accept 2 inlets, i could eliminate the y fitting, and increase flow (its all 1/2 ID tubing and a hydor l30, so there should be lots of flow) by just rejoining the rbx outlets at the res, then going to gpu. theoretically, this would also allow the water from the cpu to cool a little before hitting the gpu. is my thinking way off? plz let me know

Probably won't matter much in the end but the two most popular theories are to put the rad before the CPU waterblock or the pump before. Choose which one will allow you to use less tubing. If you can avoid it, though, don't put the pump directly before the rad. Your idea of eliminating the Y-fitting is sound. Go for it.

so where should i put the rad then? before the pump?

Nevermind....it doesn't matter.

lol really? aight ill leave it after pump

IF it were me?
Pump>>>Radiator>>>RBX>>>Y>>>M4>>>Res>>>pump

WHAT HE SAID!!!!

Remmeber your also saying that your taking hot water from cooling the gpu right into the cooling loop again without stopping at the res so your gain is lost......
its not substantial but the flip side to your gain....there is always a flip side remember that

Flip side is loss of head pressure before you hit the block. And that's substantial when running through a BIX first. For a very long time, I said it didn't matter much put it in the same order as Zennzzo. You might have a small advantage for the first 20-30 minutes with the rad just before the block. But after the system warmed up, it would all even out in the end.

But with the advent of impingement base water blocks like the RBX, WhiteWater and Cascade, I noticed a slight improvement placing the pump just before the cpu block. This puts the greatest pressure in the loop between the pump and cpu block. The least pressure at the rad and res. The rest is set-up for convenience sake and smooth, short tubing runs. pump > cpu > gpu > rad > res > pump

I say give your idea a shot. The thinking you'll have less back pressure with two outlets to the res is sound. But believe me, the pressure drops immensely just after running through a RBX. A single tube is more than enough to run the exit water. I had to squeeze the tubing behind the RBX the first time I tested with a small restriction plate to get the air out of the lines. It knocks the crap outta flow. Run your system as it is now with something like Prime95 and record temps AND ambient. Chart the difference between the two. Or Delta. Then hook it up the new way and record the new temps.

Flip case fans, change component order, eliminate sharp bends and fittings and measure temps, measure temps, measure temps. Every set-up is different, and I could set-up mathematical models to predict what would work best. If I had access to a Cray computer, didn't forget to include one of the thousands of variables and had months to do it. Believe me, it's much easier to try and test to see what works best. A quarter degree here, a half a degree there, tweaking can add up to a nice gain in performance. Just don't expect big fat whole degree improvements...not gonna happen.

allright thanks for the help guys, ill play with it a bit and see what works best... GETS HERE TODAY!!!

everything else got here but im still waiting on the res dam danger den had to have the manufacture send it. either way, i think ive decided on
pump>cpu>y>gpu>rad>res>pump
ill just deal with the y fitting being there

I have a slightly different take on it then AntiM, but mostly the same.

First off, I am a proponent of going from Pumps to blocks, to Rad, then res, and back to the pump.

This is the reasoning.

I beleave that you want your blocks right after the pump to reduce the effects of head loss. And I believe in cooling the coolest running blocks first, then the hotter ones. You see, the greater the difference in temp between the coolant and the block, the more heat it will absorb as it passes through. So, if you cool the CPU first, then it won't do the GPU much good, might as well run a fan on it and save some head loss. But if you cool the GPU first, then the water will still not change much in temp prior to hitting the CPU, but you will actually have cooled the GPU.

At this point get the heat out of the system, go to the RAD and cool things off, collect at the res, and back to the pump.

Any way, that's my take on it

its in, i did pump>cpu>gpu>rad>res>pump

pictures comin soon, had to cut up the front of the xaser and i stil dont know if i regret it or not lol

nice, what temps are ya getting and what is your proc speed?

ill get temps tonight, proc speed is 2.6 @ 3.515 regularly, 3.661 when benchmarking
