Hello,
I am hoping someone can give me some advice on going from 3/8" tubing to 1/4" tubing, as some of my blocks only accept 1/4".
Bear with me here I'm going to do some brain-storming. If I am wrong about any of this please let me know.
Alledgedly, going from 3/8" to split 1/4" will reduce flow. Makes sense as the cross sectional area goes from 9*pi/256, roughly .1104", to 2*pi/64, roughly .0982". This means you lose about .0122" in cross sectional area which makes it harder for the water to flow.
What if two splitters were used? Since only three 1/4" tubes are desired this would be the configuration:
Use a Y or F-type splitter to split the single 3/8" into two 3/8". Immediately split one of the new 3/8" into two 1/4" while using a 3/8" to 1/4" adapter on the other one. This changes the total cross sectional area of the three 1/4" tubes to 3*pi/64, roughly .1473". Now there should be no reduction in flow through the system.
If this looks right and makes sense then I would do the following:
Res->Rad->SB->NB->CPU->MOSFET1->MOSFET2->Splitters
Y1->GPU->RAM1->Y-splitter to 3/8"->Res
Y2->RAM2->Y-splitter to 3/8"->Res (allows for 2nd future GPU cooling)
Y3->HDD1->HDD2->Y-splitter to 3/8"->Res
Of course if someone makes a 1-to-3 splitter already then that would be the better choice.
Does this make sense? Could it work?

this article which states:

Presumably, the hose reducers used in the V10 loop had enough of an impingement effect to significantly increase the cooling performance of that block. As the water is forced from the 1/2" tubing into the 3/8" tubing it increases in both velocity and turbulence (like using your thumb to spray a jet of water from a garden hose). We have seen the principle of impingement used in the design of several water blocks of late, including the RBX used in this review, the effect on cooling is clear. When we switch the V10 for the V13 with its large 1/2" fittings we lose that impingement and the resultant velocity/turbulence. I would have thought that the increased flow would have been more important, but the numbers don't lie.

Now I realize this article is rather old, but is it really going to be worth it for me to have a three-way splitter?
