Quick disconnects help ? - Page 2

Also something to note: if you plan on using a threaded version of the VL4N to connect directly to a component you will have to purchase a fitting adapter. The VL4N QDC's ONLY come with a G 3/8 thread, whereas all components use a G 1/4 thread.

The adapter can be found here: http://www.frozencpu.com/products/13663/ex-tub-958/Alphacool_HF_38_Flowbooster_G14_to_G38_Adapter_.html?tl=g30c101s744

So you have two choices.

1. Use the VL3N QDC's which come standard with G1/4 threading here:

Male (threaded): http://www.frozencpu.com/products/9503/koo-184/Koolance_QDC_High_Flow_No-Spill_Shutoff_Nozzle_Male_G14_Thread_VL3N-MG.html?tl=g30c405s1026
Female: http://www.frozencpu.com/products/9500/koo-181/Koolance_QDC_High_Flow_No-Spill_Shutoff_Nozzle_Female_Compression_13mm_12_x_19mm_34_VL3N-F13-19S.html?tl=g30c405s1026

2: Use the VL4N with the adapters, here:

Male (threaded): http://www.frozencpu.com/products/11308/koo-248/Koolance_QDC_Extreme_Flow_No-Spill_Male_Threaded_G_38_VL4N-MG.html?tl=g30c405s1025
Female: http://www.frozencpu.com/products/11309/koo-249/Koolance_QDC_Extreme_Flow_No-Spill_Female_Compression_13mm_12_x_19mm_34VL4N-F13-19S.html?tl=g30c405s1025

KEEP IN MIND: these are for 1/2" ID 3/4" OD tubing. If you decide to go with a thinner tubing, you will have to change the female parts to match that of your tubing. The male threads can stay the same.

OK, lets stick to things with some facts to support them as opposed to making baseless statements. If one reads Skinee's tests, you will find information based in fact. I, personally, trust Skinee and Martin. They have shown time and again that they know what they are talking about and have the patience and dedication to improve everyone's awareness of all things water cooling.

I do back up that the fluid loss is much smaller than that stated by BMSliger.

I have used Koolance QDCs for over 6 years. I have used the 2 series and both variants of the 3 series. Restriction of the 2 series is quite high, 3 series much better. 3 series is certainly no joke.

I used these 3/8" ID VL2N's when I just re-did my loop:

Female G1/4 threaded no-spill

No spill male

I used the females that can thread directly into blocks/rads/res, it worked out best that way.



here's on the dual-bay res up front. They are a bit long when all connected, keep that in mind.



I don't think you need to go crazy and use them all over, but definitely at either side of the mobo-connected part of your loop makes life easy. I'm very happy with the VL2Ns. If you google some QD reviews, the restriction is minimal.

Obviously you have never seen or used the 4 series then, as when compared to the 3 series side by side, the 4 series are clearly for a real loop, while the 3 series are for a a child's loop. I didn't say anything about restriction rates did I? Please don't put words in my mouth.

I have seen those charts and I know there is not much difference in flow rates, but there is an improvement with the 4s. In my mind the 3 series are just too dinky to put into a real loop with 1/2x3/4 tubing, they are out of place.

The only drawback with the 4s is you have to use an adapter for the threads, as was stated.

Angled or not would depend on your case and how you plan to route the tubing. Its best to draw a good picture first and plan ahead as much as possible. For the most part though even if you just use all straight fittings it will be fine to start with. Its really all up to you and you can always change it. For instance you may not want to put the QDCs into the block as was suggested but have some tube running out from the block and disconnect further upstream to hide the QDCs somewhere else.

I can't really comment on the block you have chosen, but I would strongly suggest you reconsider the RP452x2 as I myself own it and cannot wait to replace it. If you search around this forum there's more than enough threads going into detail about it. Also if that was meant to be your complete list for your full setup it's missing quite a few things (pumps / radiators / tubing etc etc)

If this is your very first loop my main suggestion would be to keep it as simple as possible and inexpensive. In a few months you can upgrade it once the direction you want to take is clearer and you have more knowledge of what products are out there in the market.

I only listed those parts becuase i already have the rad(s) and pump. The reason i like that res is because the pump connects directly to it and i can go from res to rad to cpu etc. Instead of having to go from res to pump to cpu.

I didnt list the tubing also becuase i have some 1/2in 3/4 already.

I am mainly confused about the adapters, i have a bad case of dyslexia so this stuff believe it or not is hard for me to conceptualize .

The RP 452x2 works perfectly fine. The only thing i dislike about it is that its a little bit of a pain to fill. Other than that though I love mine, and its been going strong for quite a few months now.

Just be sure you get the latest version one: http://koolance.com/rp-452x2-dual-5-25in-reservoir-for-1-2-pmp-450-s-pumps

As for the adapters. You only need as many adapters as you have threaded QDCs. In the above post where you mention what parts you have, you have 2 male threaded QDCs listed, so you would need two adapters.

For the number of fittings you need:

CPU Block: From what i understand you are using the QDCs as the fittings for the CPU, which is why they are threaded and you need the adapters.
Radiators: Two fittings for each rad you have. (You did not list specifically how many you have).
Reservoir/Pump: For the RP 452x2, you will only need two fittings.

Now as for what kind of fittings you should buy (straight fittings, 90 degree fittings, 45 degrees fittings, etc), that will depend on how you wish to structure your loop. If you provide a representation of roughly where you wish to put your radiator and in which bay your reservoir will go, I many be able to help you form your loop.
