So what is your opinion on hoses and couplers in your cooling loop? Curious if anyone has noticed much of a difference in using a larger size tubing in your cooling loop for better flow and/or if much of a difference in flow if using quick couplers. I have always been using quick couplers for ease of removing individual parts if needed and swapping out parts but wondering if there is much flow restriction in using them. All opinions welcome.

    Hose size can get too small and make a big difference.  1/4 inch tubing constricts flow a lot relative to 3/8 and 1/2 tubing sizes.  There isn't much difference between 3/8 and 1/2 inch, though, mostly due to the constriction in G1/4 fittings.  Those fittings constrict to less than 3/8 inch for a short length.  It doesn't take much length for a reduced inside diameter to dominate the flow rate. The result is roughly the same flow through those sizes.
     
    Angled fittings and swiveling fittings constrict even more than straight fittings because their inside diameter is constricted more.  The quick couplers I have tried are worse yet, but your result may vary depending on the inside diameter of the coupler you use.

    Yeah when i started playing with the custom loops a couple years ago i went with the 10mm/13mm hoses and used quick couplers as well and have never changed, but now i'm going to switch over to the 1/2" ID hoses and eliminate couplers so i'm thinking could change flow quite a bit for the cpu loop.

    Another option is to step up your pump game.

    This is what i have been using, seems to have plenty of pressure.

    Probably why you still have decent flow if you're within spec that is. 
     
    Quick-disconnects while I used to use them on my first ever liquid cooling loop, can add a good amount of resistance but if your pumps can handle them and your flow is good, I don't think it matters but QDCs are great for those that swap gear more often than the average joe.

    Yeah i might not see any difference at all after doing the switch but at least i will have better insight about my system.

    I've used 4 of the Koolance quick disconnects long ago and I'd say not even a year later a few jammed up and would not seal when disconnected. Never used any since.

    Thats the kind i have right now but after a few years they all still work properly and seal when disconnected.

    Well this was prob 10 years ago.. inner springs wouldnt close the openings.. prob changed some since then.
