New Koolance quick disconnect nozzles

[Navanod]

Hi guys,

I've been looking with interest at http://www.koolance.com/water-coolin...hp?cPath=62_60

Since our major concerns had always been flowrates, what do we make of these new "high flow" nozzles?

Also, another problem with such nozzles is the total combined length of the assembly. A rigid 3-4 inches straight section is never easy to work into a loop...

[csjsi]

Copy that, it would be great to see someone review these.
Just how easy would they make changing your loop around and testing stuff.

[Navanod]

Alot easier I would say...esp valuable would be the option of removing the radiator for a thorough cleaning as well as being able to "prefill" the rad so any trapped air bubbles can be rotated out ex-situ
the pains of tumbling a TJ07 can be legendary

[QuadSLI]

Would this work as a Drain port??

[MrToad]

They look cool. However, quick disconnects with shut-off valve are restrictive, and swivel (banjo, not the hydraulic cone-seat ones) fittings even more restrictive, so if you combine the two you get...

Yup, a 4 mm accelerator nozzle on each fitting. I don't know, if you have two Iwakis @24V in series you may not care, but for the rest of the mortals is a no-no.

Edit: If you ever wondered how a banjo elbow works, it's one of these on one of these. It's not rocket science to work out that's going to be restrictive. Just look at the size of those holes. I have a couple here at home and in my fittings they're 3 mm. And after negotiating the improvised accelerator nozzles, the fluid has to flow through the 4mm deep cavity formed between the outer wall of the bolt and the inner wall of the nut.

Put four of those in your loop and enjoy

Would be fine for low-flow folks, not for the real users

kinda wanted to play with koolance fitings on my next build sincenthey finally make them from nicle plated brass now. instead of annodized alu.

Take a look at this thread... http://www.xtremesystems.org/forums/...d.php?t=163115

Has there been an actual conclusion as to whether the Koolance quick disconnects are significantly more constricting than the McMaster ones or not?

[Cptn Vortex]

I always thought that would be a good idea to have. Kinda neat

yeah.

CPC Colder makes the best quick disconnects.

The koolances would only be good as a drain line or gpu loop. I wouldnt touch it in my cpu loop.

Thank you.

I'm using the Koolance disconnects in my loop and have very very little (if any) noticeable flow drop in the system. All of my connectors are koolance, I've never had a leak and I don't have to hassle with plastic connectors or wire ties. They are VERY easy to use and never leak.

I'm sure the McMaster connectors are great but I refuse to start trying to mess with tubing clamps and plastic.

I use the Koolance connectors with MasterKleer (sp) tubing (3/8), have a CPU block, ATI 2900 block, Northbridge and of course res and the Koolance 4 fan rad. Never had a leak at any point in the system and which has been unchanged for a year + with the exception of the new quick disconnects (which made swapping in the new radiator a breeze.)

Anyway there's nothing else out there I'd consider using. However if you plan on using thick rubber type tubing you'll have to pass on the Koolance as it won't support overly thick walls. But most of the recommended tubing here works fine and the MasterKleer is great stuff.

These disconnects are all so wimpy. I want a giant lever with a red handgrip that is barely moveable by human force and gives a loud KLONK when it's down all the way. It should also make a large hissing noise when it shuts down the valve.

I think I've played too much UT3.

once again take a look at my pictures. You see that black thing in the middle? Thats NOT how CPC's look.

On the Koolance even connected theres a obstriction. Water needs to move around that black thing cuz the two black things on the female and male push each other to open pathway.

On the CPC, there much more open. Trust me, id use them however there uber ugly.

Anyhow martin is gonna get a sample from me soon to use as a drain line on his loop and keep. He promised me in exchange he would do a flow chart on it. So i'll show you.

But no, even when you blow air though them, you feel restriction vs blowing though a straight tube.

yeah lately the responses ive been reading made me bring my avatar back.



Guys a part of a forum, is having people that has GONE though a lot of first hand eq.
We know what works, what doesnt, and what is still in the air.
Use our budget we spent and learn from what we give out. :P
Ask for pictures if you require it, im sure one of us will have pictures on what you want!

I personally am a very camera happy person, most likely i'll have some pictures of it if it pertains to h2o!

I haven't seen the CPCs (checked the site but it's abysmally poor at helping you find things!) and I'm sure they perform well, probably less restriction as you say than the Koolance.

My comments are on my success with using them. So far they've been great. Are there others out there with less restriction? Probably, but for the most part I haven't seen any designed as well as these from the perspective of requiring no clamps and brass construction.

Personally I don't see the design causing any visible loss of flow or temps before or after I installed the 2 QDs. Now if I went nuts and added them at every block in the loop it might start impacting things noticeably, but I'm not insane ;D

I have no issues using them outside my CPU loop.

Remember im a bleeding edge whore.

<3 them on my gpu loop. Makes swaping cards UBER fast and UBER easy. Gpu's dont need more then .5gpm. The blocks and pins are nowhere near complicated as the more modern blocks.

I bought one of these just to see what they were like and also to see if it is any good before buying more because they are expensive. Good thing I did that because it does not even fit my tygon tubing (cannot screw it down) and the center black part is restrictive despite being labeled as high flow. Needless to say it's collecting dust.

Koolance has a flow chart, this is the one for 1/2 female:

Hmm, wonder if that testing was done at the automotive testing facility?....you know, the one that says their rads out perform a TC.

[migueld]

If I'm reading that correctly... the pressure drop is huge?

At 7 LMP which is 1.85 GPM, the pressure drop is about the same as a Fuzion V1?!!

Which would be a shame because I really love these types of fittings, I've been thinking of getting some for my loop.

i told you.

[migueld]

Dunno maybe I'm just reading it wrong and it's not that bad... If it's similar to an elbow then having two of these in a loop should be fine. Hmm....

[migueld]

Upon further investigation I found some of Colder's flow graphs which look a bit troubling:





These quick-connects seem well apt for high pressure, hence the crazy PSI scale. According to the graph the minimum PSI starts at 5 which is very restricting. I do realize that the graph may not be accurate since it's large scale, but it doesn't look too promising. I'd love to have some real world tests on these things though to see where they stand.

thought some people would find this info handy.


I was looking at the 3/4" model and at 8 L/min it has a PSI of .29 which shouldn't hurt flow too badly.

The 1/2" model at 8 L/min or 2gal/min it has a PSI of .625
