DUAL Loop or Single Loop

[Osborne3]

Hey my friend thinks that I should combine the dual loop I already have into one big single loop because he thinks I am not utelizing the 480 rad in my cpu loop for some reason, basically I have come to you, the experts to solve this quarell.:D
This is what were basically argueing about he is saying that one loop like this.
PUMP-480RAD-CPU-MOBO-PUMP-240RAD-GPU-RAM
Is better than two loops like this:
PUMP-480RAD-CPU
PUMP-240RAD-GPU-MOBO-RAM
The Same amount of cooling hardware and components the difference being that one is a dual loop and one is a single loop. I personally think they would perform the same. He thinks I would get better performance out of going the one single loop. Can someone please correct one of us :D

Which pump?

What CPU and GPU are you running?

Yp, we need to know that too;)

Ok I got two MCP355's and I am using a Intel Core 17 930 and a GTX 580

You might be better off with 2 pumps in one loop, for redundancy.

[Wega52]

You really should put the 480 on the GPU, as it releases a lot more heat the the CPU.
I think your best bet is to put the GPU, mobo and ram on the 480 and then the CPU on the 240.

I agree and I doubt that loop order will make that much difference.

One loop ftw :clap:
That way, no radiator space is wasted when either component is not running at full load. Your friend is right, you're not utilizing that 480 rad for just one CPU.

Unless your CPU runs at 100% 24/7 :cool: And even then I would consider a 480 overkill.

Gabe did a thorough test regarding this (http://www.xtremesystems.org/forums/showthread.php?t=254683), it might be worth reading.

1 loop. You have 1 gtx580 if you had 2 or 3 I'd split loops. 2 pumps will help flow in 1 big loop.

single loop FTW

2 pumps not only help for redundancy but if one pump fails your computer will still operate while your replacement pump arrives.
also only having the one res is a bonus for room.
one loop to maintain.


id go
RES-PUMP-GPU-MOBO-RAM-480RAD-PUMP-CPU-240RAD-BACK TO RES

maybe just switch the ram from from the GPU side to the CPU side depending on case room and asthetics

for intrest my loop has 2 480 rads in the one loop and its over kill still,
res-pump-3xGTX580 in parallel -rad-pump-cpu-mobo-480rad. so as you can see 1 480 rad will cool 3 over clocked 580's that why you could definately spread the efficiancy of your cooling system and maybe get better cooling and over clocking results, and save your self some maintenance work in the future

single loop here...

running CPU, full board, dual GPU

going like this: Res>Pump>CPU>Mobo>GPU>Rad>Res

i WAS running with just a 480 double thickness radiator and got by fine with decently high OC'ing (refer to sig)

now i'm running 1080 double thickness (MORA3 Pro) with fans runnin slow, same OC'ing and dead silent... and loooooviiiinnn iiiitttt
