1 loop or 2?

post #1 of 21
Thread Starter 
Ok, me and [S][R] were chatting.
I told him the cost of 1 loop would be $400 out of 2 loops. So about $600 total.
I want to you to keep in mine now that I ALREADY have 2 Black Ice 360GTX rads and 2 Dtek 8800GTX blocks (and uni sinks).

If I were to get 2 loops, this is what I would get.

Res x2 = $60
WireExtensions/Splitters = $20
Additives = $15
Tubing x10 = $10
Fans x14 = $80
Controller = $35
Mesh x14 = $25
Pump x2 = $180
Fuzion CPU Block = $80
======================
Total = $500 without shipping and other -little- things like lights.





But, for 1 loop.....
Res = $30
WireExtensions/Splitters = $20
Additives = $15
Tubing x10 = $10
Fans x14 = $80
Controller = $35
Mesh x14 = $25
Pump = $102
Fuzion CPU Block = $80
=======================
Total = 400 without shipping and other -little- things likes lights.



If I do 1 rad on 1 loops

Res = $30
WireExtensions= $10
Additives = $15
Tubing x10 = $10
Fans x6 = $31
Controller = $35
Mesh x6 = $11
Pump = $102
Fuzion CPU Block = $80
=====================
Total = $325

Whats the best solution?
Also - for a single loop.... what other pump can I use that doesnt need an external power source and just right off my PSU?

The question you should ask yourself is this:

"Is it worth it to me to spend around $100 more to give my CPU the lower temps (not sure how much, 3-5C maybe, someone confirm or correct please)?"

If the answer is yes, then two loops.
If the answer is no, then run a single loop.

However because you have two 8800GTX's, I'd say the extra $100 or so is worth it when considering the heat dump the GTX's will introduce into the loop. Plus you already have two radiators...

You could, but I'd be a little concerned about the flowrate, even with the D5 vario on the "5" setting. Then again I know absolutely nothing first-hand about watercooling, so what I've just told you is what I've been reading/hearing around the forums.

First, I would not even factor in those components that are common to either decision. You purchase those items regardless of which way you go. In the single loop scenerio, Why a different single pump (alphacool) than the dual loop (MCP655). More flow rate?

Martin (slap me if I'm wrong) stated that there's not much cooling performance gain in flow rates over 1 GPM. Use his Flow Rate Calculator to see what the estimated rate with the MCP655 in the single loop. If it's comfortably over 1 GPM then you might go with that and save more on the single loop.

By-Tor had a dual rad single loop, but recently broke it into two loops. I'm curious to hear how that affected his temps?

One possible side benefit of separate loops is using two different colors of UV fluid in them. It would look cool, and offer some practical benefits (visual inspection) as well. Since I have two pumps and a spare rad, I'll probably go with two loops in a few months.

The different pump is for flow rate. There will be barely any with the MCP655 left over, it'll work yes but with little to spare. This is because the Dteks are extremely restrictive or so they say.

That Ap1510 is as powerful as a rd-30 at 18 volts, which is you what you want to run them at, I suggest single loop.
