Advice needed. 1 or 2 loops?

post #1 of 9
Thread Starter 
TL;DR version:
1 loop or two loops (1 for CPU and 1 for GPUs) considering QDCs and high load and maximum heat removal.

Longer version:
I'm going to replace the motherboard with a non-watercooled one.
Considering putting the CPU on one radiator on its own loop.

It will be two loops as followed:

Res->655->CPU Block->Radiator 360->Res
^-> 35X(2)->GPUs->Radiators 360 (2)-^

Or one loop as followed:

Res->35X(2)->Radiator->CPU->GPUs->Radiators (2)->Res

I don't have bad temps now, but I might go a bit better. Not sure.

Getting rid of the motherboard blocks should increase the flow and the temps a bit.
Also one loop allows me to use less QDCs (1 before CPU and one after GPUs only) so that I can remove the motherboard tray with all its items quickly without any need for removing more than two QDC connectors, which also reduce the flow.

Mostly I'm using this change because its never "just right"

Fat_Itallion Stallion has a system similar to yours and found that going for dual loops didn't change his temperatures at all. However, If I read that correctly you say dual loops would allow for easier motherboard removal? I'd definitely go for it then, especially since you already have all of the parts.

Single loop will be easier for removal.

On single loop:
->Rad->QDC->CPU->GPUs->QDC->Rad->
So only 2 QDCs

Dual loop:
->Pump->QDC->CPU->QDC->Rad->
->Pump->QDC->GPUs->QDC->Rad->
Now its 4 QDCs.

I'd go for the single in that case. Very rarely does dual loops equate to better temperatures.

You have 3 360's in one loop?

Yes. 3xGTX360 radiators with AP-15s at push/pull with shroud.

I'd just stick with a single loop then. Dual 35Xs with an XSPC or EK Dual top should be giving you some great flow rates even through that ridiculous loop.
