I apologize if something like this has been presented before but searching these forums and the internet I couldn't find anything similar. Who knows, maybe I don't know how to Google or Bing stuff correctly.

Keep in mind that I am pretty new to watercooling myself, so if any of the vets out there has anything to add, I'm open to any suggestions/recommendations.

Anyways, for the longest time I wanted to try watercooling but I'm the kind of person who likes to tinker with his computer on a frequent basis (which makes me the norm on this forum I'm pretty sure) so the thought of having to constantly empty an entire cooling loop or the very least clamping down part of the loop with risk of fluid dripping on my components just didn't appeal to me.

So over the past years I've just been dragging my ass on watercooling. Recently, I came upon Koolance quick disconnects and after reading this article:

http://www.skinneelabs.com/qdc.html

I was convinced to give WC a try this year (apparently skinnee website is like mud around here but at least that website did point me in the right direction).

I settled on the Koolance VL3N male and female connectors:

and

The following pic was my first attempt at WC:

I thought it was a decent attempt considering it was my first time but as the next pic would show the connection from my videocard back to the reservoir was demonstrating an angle I was uncomfortable with:

I had to order and wait for a 45 Degree swiveling fitting that I thought would alleviate the problem. After getting the part in, it was really easy to install it as the following pics will show.

First the Koolance fittings made disconnecting a snap. I actually got ahead of myself and started to drain the tube until I remembered I didn't take a picture and reassembled the connector back in order to take a picture which is why the tube is only half filled with fluid:

To drain the fluid from the tube I first took of the male quick disconnect fitting which is connected via compression fitting (should have took a picture of that. Oops.) Then I used a syringe that I swiped from work and paired it with some tubing from Home Depot.

After draining the fluid the rest was cake. I was able to easily disconnect the old compression fitting:

Installing the 45 degree connector and then the compression fitting and then the tube and lastly the same Male quick disconnect fitting was really simple. I should have taken an intermediate pic but instead I just took this one after everything was reconnected:

You can see that fluid from the reservoir already started flowing back into the tube after the loop was closed.

A more natural connection (and one which didn't have me worried that something was eventually going to break) was the final result:

All in all, even with stopping to take the pictures, the entire process took less than 15 minutes from start to finish. I guess I should have stopped more often to take more pictures but oh well.

Keep in mind that this little project was just to replace an old connection. If I wanted to actually replace the videocard or add another videocard it would have been just as simple.

I am really happy that I invested the extra cash and effort on these quick disconnectors and hope that this info encourages others to take the jump into watercooling in case they had the same reservations as I did. And no I have don't have any ties to Koolance whatsoever

Sometime next year I'm planning to build a new system and you better believe it's going to be watercooled.

Just want to say thanks to this forum because you guys are the reason that my computer is a hobby and not just some beige box. My wife on the other hand actually hate you guys but then again that's another plus (just kidding she's great).

Also thanks to Performance PC's which is where I bought pretty much all my watercooling supplies and who took the time to answer my noob email questions.
 
Looks like a great build for a start. I used fittings similar to todays Colder HFC12's back in the day as well in 2002 (which all source from medical in-line connectors re-purposed for watercooling in PC's). Remember though that adding more and more quick disconnects to your build will impact the volume of liquid flow as it increases flowing resistance. Due to the way they operate to stop fluid from leaking, this can have an undesired effect. Watercooling can have some great returns and it looks like you are going to enjoy it.
 
What's with the syringe and all? I thought the point of the latest QDC was that you can take it apart without literally a single drop of water in your way.

(Though obviously if you have a syringe and the appropriate smaller tubing, it's a moot point.)

e: Never mind; misunderstood where the QDC was in the loop. Nice and clean, though everything tends to looks damn nice in the 800D.
 
Looks great, especially for a first wc build. Now it's time to sleeve those psu cables!
 
Bill thanks for moving this thread. I didn't realize I put it in the wrong section.

And thanks for the support guys.

Mickey21. Are you talking about the cooling devices they use for surgical patients? The cooling device itself looks like a icebox and the quick disconnects connects it to a sleeve that's in direct contact with the body part.

If that's what you're talking about then what's funny is a few years ago I actually talked to one of the equipment reps about the possibility of using it for watercooling. He thought I was crazy but was willing to loan me a unit to test it out myself. I nixed the idea because for one the rep wasn't sure if the pump was reliable enough to complete the loop and if it was, then more than likely the temp would get so low I knew there would be condensation in the box itself.

Matrices. You're right. It's almost like cheating when you have an 800D case. It's so easy to make the inside look neat and tidy. But notice I didn't include any pics of the other side...

Atara. Don't even get me started on the sleeving thing. That's going to be my next project. The other day I bought a heat gun but they didn't have the correct heat wrap size and I haven't had a chance to run to Frys or Micorcenter yet.

I really would like to get another power supply to match the case but the one I have right now is a 750W from PC Power and Cooling and it's working like a champ so it's hard for me to justify that purchase. Soon though. Soon.
 
No, actually talking about the disconnects themselves, but yeah I see your other point. (Used to work in a hospital) and so I know what you mean. But yeah when I sourced my quick disconnects, I ordered them from medical supply companies and there are a lot more variations then say the ones listed there. There are some at right angles and so forth. The alloy ones are made by the same company that makes the resin ones if I remember correctly.
 
I might have to get a pair myself when I change out my tubing. Any leaking problems? I know some of the Koolance QDCs had leaking problems.
 
What kind of coolant are you using I can't never get that kind of blue :(
 
Mickey21: I'm noticing more and more QDC's in the hospital from the cooling devices to blood pressure cuffs and compression devices. I don't know the kind you've worked with but the ones I'm used to, they all have some type of leakage when disconnected.

Which is why I really like the ones I'm using. There's absolutely no fluid leak at all when they're disconnected. Well worth their price (but hey if the price goes down I wouldn't mind that either)

x509: If you mean the upgrade in this post then it's only about ten bucks since I just needed to get the 45 degree swivel fitting (Bitspower). I was able to re-use the old compression fitting and the tubing. If you mean the entire WC upgrade then that's a little more expensive :(

Soulesschild: It's been 3 weeks and no leaks so far. That includes multiple disconnects. I had a leak in my first cpu waterblock and had to pull it out several times before finally getting a new one. That really sucked but again if it weren't for the QDC's life would have been a lot harder. Anyway, even after all that those connectors are holding well.

The real test is going to be in a month when I go to Austin for a friend's LAN party. I plan to buy foam or some other type of soft material to pack into the case to help keep everything in place. So if my WC loops hold with my driving then those components are all solid.

Sickboy: Those aren't colored tubes. I should have listened to everybody else and just use distilled water. The tubing (Tygon) is clear and the coolant I bought from Microcenter. After the leak I mentioned above, I noticed the the coolant is not as viscous as say water and does leave a residue.

Being the impaient person that I am, I didn't even bother to test it before pouring it in. I can only imagine what it's going to do to my system in time. Soon I'll be flushing it all out and just use distilled water or get colored tubing. Not really sure yet.

Have you tried the tubing options from Peformance PC's? The blue UV tubing looks similar but of course you can't really tell from just a pic

PrimoFlex Pro LRT Black Tubing -1/2in. ID X 3/4in. OD some of the best shit u can buy i love it its flexible yet stiff and less kinks. just make sure its the PRO LRT. UV green glows well under UVu can also get the ANTI-Kink Coils they add a nice look to the tubing as well. those quick disconnects are killer on the wallet just for 4 sets of the VL4N Extreme Flow. rather have max flow but i might get verson 3 no leak to save money since im also splitting the loops for cpu and SLI. each on there own 120.3 rad
 
Very nice. I need to order more of those connectors myself.
 
looks like the new VL4N male threaded is only 3/8th thread would that mess up with a rad or mostly everything thats 1/4th? either way $160 bucks for 6 sets really is to much.. $133 for the VL3N's

I count at least 5 there. Somebody has a QDC fetish. :D Nice little loop though. What temps are you seeing?

You sure do. I'm so glad I got mine.

performance-pcs.com is the cheapest so far

Negative. Ordering from Koolance direct is definitely the cheapest. I looked around at every shop that carried Koolance QD's and even after shipping ordering direct from Koolance proved cheapest.
