Ram Water Cooling loop
I was curious how about finding fittings that would allow 1/2 " ID to be broke out to 4 x 1/4 " for the OCZ ram Coolers and rejoined back to 1/2 " on other end of ram, just to keep volume of fluid close to main loop volume.(Parallel Cooling)

As it is, I would be required to choke down the 1/2 " to 1/4 " then daisy chain the ram in series with the 1/4 " tubing, returning to 1/2 " after the ram.(Series Cooling)

Any thoughts or sources on or for this type of fitting ?

Koolance makes one:


Tubing Splitter, Y 13/10-6mm, Quad - Water cooling systems, pc liquid cooling kit, cpu, video card, hard drive

NCIX used to sell them, I dont think they do anymore, unless I missed it.

That's pretty cool looking, but I wonder what it effect it would have on flow.....

I'm thinking it could go either way......

Either the fact that there are 4 1/4 nozzles coming from a 1/2 tube would allow max flow rather than trying to push it through a single 1/4 nozzle, or the 4 nozzles would severly choke the flow.....

Anybody out there with flow dynamics in their background who'd care to make an educated guess?

Half-decent enough, I suppose. Cross-sectionally, 1/2" ID equals 4*1/4" ID, so your main issue would be the turbulence created from the split (Koolance's fittings all tend to be pretty mediocre in this department), plus (perhaps) an slight increase in fluid-tubing contact because you've got twice the tubing surface area. But really, it's not like OCZ's Flex RAM is a paragon of free flow to begin with, and you're looking at a 1/4" bottleneck within the RAM itself. If you're determined to go from 1/2" to the RAM, this fitting would probably make the best of a bad situation.

Ideally, this would happen in a secondary loop, because this would punish your CPU/GPU temperatures otherwise. And personally, the "Anodized Aluminum" in the materials for that splitter would be giving me the creeps.

Are you determined to watercool your RAM? OCZ's Flex RAM gets good reviews, but I have yet to see a single review anywhere stating that watercooling got them a single MHz increase in headroom. At best, you might be able to take the edge off your in-case temps.

Just add a nice quiet fan on top of your ram and its case close. But if you really wish to wc the sticks, aren't those fittings designed just for this application?

Great find fellows, the Cooldance stuff looks great, I am already reduced to
3/8 " from 1/2 " due to Northbridge Barbs on the mother board and I felt an addition all hit to 1/4 " on the ram would be too much back pressure.
I have a nice 4 " fan on the ram , it keeps the temps at 33c-36c at full load after 24 hours of folding, so its doing OK

Turns out the water cooled stuff probably wont work on the machine as it is rated for PC2-8500 and the Flex stuff is higher.
