Rad recommendation

gatecrasherlok · 22 Feb 2012 at 13:26

Hey guys, I'm slowly gathering bits to water cool my rig. Just recommendation for rad size for my graphics cards and amount of pumps for my particular setup.

Got so far

laing d5 vario pump (variable speed)
TFC - 360 Radiator
ek - HF cpu block
ek pump top

As you can see this is mostly stuff for my cpu. However since I am going to water cool I thought I might as well get my gpu's under water too.

So questions that I need assistance with.

One single loop - cpu/2gtx590 blocks and maybe a ram cooler for looks
(will one d5 vario be enough to provide enough flow for this loop)

Or 2 seperate loops. If I get a seperate loop I'll get another d5 vario as that seems to be the tried and tested by many and I previously have not had problems with them before. However if i go down this route, would a 240 sized rad be enough to cool the two 590's or should I play safe get another 360 rad.

Next question is I want to get compression fittings but i have no idea what size goes with what.

I have been looking at the following

So question I have is what type of tubing would fit that. In addition to that I like my loops to have relatively fat tubing (as long as its not skinny looking), will this give me that illusion?

If not which compression should I go for and tubing size to go with it too.

Sorry realised I wrote in the title it was rad recommendation and I started totally offloading all my queries.

Thankyou very much guys.

The way the system for tubing works is that the 7/16 part is the ID (internal diameter in inches) this is equal to 12mm internal diameter.
Thus the second figure quoted 16/12 refers to a 16mm ED (external diameter) and 12mm ID (internal diameter).
Thus the tubing you need it 16/12 tubing.
I have 3/8 13/10mm tubing and this is sufficient, the really thick stuff (1/2inch) stuff is good but hard to get to bend so look to have few bends in the loop if that is the case.
The G1/4 refers to the thread of the compression fitting.

for Rads you are looking at maybe a 360 rad and a 240 I would say minimum.

Cheers lollyhayes but 360 and 240 for one single all componants loop or 360 and 240 for gpu's alone?

I currently run 2 x 240 and 1x 120 in a single loop. RES - PUMP - CPU - 240rad - GPU - 120rad - GPU - 240rad

Single loop is simpler and cheaper. The dual loop will stop crossover of high temps from your GPU's to CPUS, but on the basis of using a 360 rad and 240 rad you might find that the 360 in the GPU loop was insufficient and and the 240 rad in the CPU loop was sslight overkill.

Hmm, 360 might be a problem in cooling my two graphics cards. Hmm may have to think again then, I thought the 360 would have been enough.
