Thanks for the replys.

I did not read that article jet.

This guy ends up with a nice clean system. If I would only cool my CPU, it would be "simple".

This is what I have, and what I want to cool:
Hydror L20, (**2x**)
BlackIce Pro 13mm in/out
DTec Rad 13mm in/out
Astec rad 8mm in/out
Whitewater CPU block 13mm
DD Z 875chipset block 13mm
Innovatek Graph-O-Matic 8mm
Innovatek Graph-O-Matic Gforce4 10mm
Koolance Hard Drive Cooler 6mm (**3x**)
Dangerden Reservoir round, 10mm
Astec reservoir round 7mm

CPU P4 2.8, (OC'ed to min 3.5Ghz)
GPU G-force4 (Not OC'ed
Nothbridge
3x HDD

Going from the CPU to the NB needs to be quite a loop, if I want to use a serial setup.
Same goes after the NB to the GPU.
Then I need to split fo het to my HDD's... in total 6 hoses (3 in, 3 out)

This is why it looks like spaghetti.

I want to reuse as much as possible (i paid for it....), as long as it is usefull.

My hose with the T's was a bit simplefied. this is what I'm building:
http://www.liquidninjas.com/photopo...o.php?photo=982

It will act as a reservoir, and as a way to distribute the water.

As I want to reuse as much as possible, I want to use all 3 radiators, split the tubing in 13/13/8mm, and make a second reservoir, where the water from the rads flow into.
This will acht as feeding res for the other pump. (first one gets feeding from the first reservoir)

I'll be using 20mm hose, from the res to the pump. That should do the trick (I hope)

So, if I get it correctly, the only reason to gain more head, is to overcome the waterflow loss that is coursed by the restriction of all the items used (waterblocks, hoses e.g.)

At a certan point a waterflow increase won't add anymore performence gain so then a higer pressure between the copper of the block and the water will give some performence gain.

I did read in a article that the minimal temp diference between the water and the copper wil be with a hig flow about 2 degrees celcius. Adding extra pressure will gain you an other 1 degree.

If you are working with a low flow, then that 1 degree gained by pressure will be a lot more, say 3 degrees.
But I don't know if that increased pressure will be better than a high flow..................

Did anyone messure? a block with a 300 l/h flow (flow is 450, but 150 goes to the GPU, NB and HDD's) and "no" pressure or a block with an 150 l/h flow with high pressure.
This is in theory the flow rates I will get with a paralel or serial setup. In the serial setup I did place the 8 and 6 mm's paralel, to sustain a reonaseble flow.
