Koolance QDC3/QDC4 Quick Disconnect Preview

Playing around with the new QDC3/QDC4 Koolance Quick Disconnects for PC water cooling. Plus a size comparison to the VL4N series

[@Diegocobos]

Thank you, your video helped me alot to decide which one to buy

[@jaywalker.]

Great explanation, thank you!

[@Metalhead-4life]

Very informative, thanx!

[@extremerigsdotnet]

Interesting - I'll have to check this. The actual internals should be the same so that's unexpected. Thanks for the heads up. If it leaks because the center of the QDC is not flush with it's surroundings immediately after taking a pair apart then that can be a sign that there's an issue with the spring and Koolance should replace it :)

sweet

Thanks for the info. Question, is it plausible to put these onto the pump in and out? I have a large external radiator with pump attached, which is a bit of a pain to shift if I want to move my pc. Solution is these on as above, would this work or would it restrict the flow too much with it been directly on the pump and/or risk leaking?

[@joesaiditstrue]

my qdc3s leak a lot more between connects/disconnects compared to my VL3N's, not sure if mine are defective or not

[@GarrySkipPerkins]

I cannot get my QDC3 apart. How do you do it? I could do the twist ones, but not these.

[@megakiller999]

so in the middle there's what looks like two over lapping rings. you need to pull them down (away from the ridged side, if that makes any sense) and it will come apart with a popping sound.

Could I connect between radiator and soft tube?

[@jesslyc.5423]

where can we buy these QD3 sets?.

[@daverow1349]

Personally, I would *never* connect a QDC directly to any waterblock! These focus enormous amounts of leverage/stress directly on a few threads, often in an acetal block. For example, just think about the stress that directly transfers to the threads, waterblock cover, and pin/grid array under your CPU, as you press downward or pull upward to open or close these QDCs! It's *much* better to connect your tubing to static fittings on your waterblocks and place these QDCs strategically several inches away, to allow interchange of the GPU, water pump, and possibly CPU sections of your water loop. So, any flexion from operating these QDCs (or other movement of your tubing during other maintenance activities) will be largely absorbed directly by the tubing and not by over-leveraged direct-attachment points. As a bonus, you're keeping all lost water *away* from your components.

Why do you think that matters? Guessing?

@@antonstjernquist2827 Prrreettyyyy sure I gave at least 4 reasons.
