Where to put 2nd Radiator into current loop?

XSPC ResTop and Laing DCC-1T 18W Pump -> TFC 360 Radiator -> DTEC Fuzion v2 CPU Block -> Swiftec MCW-60 GPU Block

I bought another triple radiator (XSPC RS360) to add to my current loop. but where would it be most effective?

for ease of mounting i was thinking:

XSPC ResTop and Laing DCC-1T 18W Pump -> TFC 360 Radiator -> DTEC Fuzion v2 CPU Block -> Swiftec MCW-60 GPU Block -> XSPC RS360 Radiator.

so i would have rad>pump>rad.

or should i stick in between the water blocks?

my graphics card is overclocked but it max loads at 40c. my main priority is the CPU temps and the water temps at entry into the CPU block.

i have currently have a inline sensor straight after the GPU block and that is at 30c. i need that lower.

It doesn't matter where you stick the radiator in the loop from a cooling point of view.

this is not always true. Especially with muliple radiators, you would definatly see different sectors of the loop that has slightly lower temps.

If by slightly, you mean substantially less than 1C?

depends on flow rate, a fast flow system will be more efficient at getting thermal equilibrium. But it is completly obvious the outlet temp would be definatly lower than inlet temps.

But in my case my pumps is heavily under volted, so the effect of multiple pump order should make a difference.

This is all theory, not installed it yet. And if it only give me a 1c decrease, then it will be a 1c decrease.

I will not be adding another loop, a triple rad for just the GPU is just not needed.

my current TFC Xchanger is rated for about 1000W of heat (dunno exactly) but i want to depense the heat dump over 2 radiators.

say about 150W of heat comes from CPU and 100W from GPU.

I want the 150W (CPU) to be cooled with 1 of the radiator then the 100W (GPU) to be dumped with the other. In effect the maximum water temp (at any given point in the loop) would be lower.

I have not seen 'Cathar's results' but all rad reviews i have read showed much higher delta T.

So I think:

XSPC ResTop and Laing DCC-1T 18W Pump -> TFC 360 Radiator -> DTEC Fuzion v2 CPU Block -> XSPC RS360 Radiator -> Swiftec MCW-60 GPU Block.

just so happens the above gives me minimum tube bending aswell

yes i know another triple will make my flow rate suck, but the XSPC rad has very low resistance for a 120.3.

I bought it knowing that, and it will be mounted horizontally to minimise resistance.

edit: as for the noise, i have a T-balancer now to turn all fans of when surfing/movies, complete passive at idle 45c.

What i mean is that with horizontally mounting, the thread will be left/right instead of up/down.

I am adding another radiator because my CPU overclock is no longer stable after i added the GPU block. temps raised to 78c max and was 71c max before.

It is going in a P182, triple cutout on top, and a swiftec radbox in the back (so i can always take it off if does not work). The radiator only cost £15 (used).

I am by no means new to watercooling and it is a matter of trial and error. I am very happy to accept opinions but it does not take long to physically try it my self. I might well need another loop but it cost nothing to try. it is bleeding atm, will get result soon.

1). ok, i accept that.
2). definatly seated properly, i took the GPU block out and tried and temps dropped to ~73 straight away. (btw i have a q6600, 1.54V @4.0Ghz)

screeny before i added GPU block: http://i24.photobucket.com/albums/c45/BornEvil_/q66004ghz.jpg

3). lol, go easy there. i know people are trying to help and i have no intenstion to embarrass myself or anyone by proving them wrong. Its just friendly therory discussion. Unfortunately i had to take all blocks apart to drain and refit different lengh tubes.


but one thing for sure is that water temp @Idle are 2c lower, it is now finished and priming atm
