One 1/2" Elbow = 4' of 1/2" ID Tubing (Test Results) - Page 2

post #11 of 28
I think the next course of action would be a little more involved. Here's what I'm proposing:

Take your watercooling setup out of your case. Plumb in a CPU/GPU/NB (A combination would be best) block(s) and do your tests- That would answer the "real-world" test because as you have noted quite well, as flowrate goes down, so too does the drop induced with the elbow.

Again, if you're up to it. I would be interested to know

But it doesn't apply to a 1/2" hose fitting elbow, because the ID is closer to 3/8":
If you have a true 1/2" elbow would it still give you the same results. I mean one that is actually 1/2"ID on the elbow that way its not like testing a 3/8ID and using it as a 1/2ID results, if you know what I mean.

Good review and excellent info

Yeah I can do that, I'm thinking of adding a NB block to my GPU loop and when I do that I'll have to drain the loop again anyway.

My guess is the tubing equivalent is probably roughly the same though because as the flow rate goes down the friction loss in the tubing goes down as well ,but the I agree the same test on a loaded restrictive loop would feel alot better in knowing how it applys to real world systems.

I'll plan on that when I get that NB block, I was interested in getting a flow rate of my two loops as they are anyway.

That would be nice to get a NB block in there and show some results that way everyone that worries about adding a NB block can see how it will effect there loop potentially.

That would be superb I can get you a diagram of what I'm thinking of so that it would work out really well and you'd be able to get some really great results.

Sounds good, it might be a little while before I get the block upgrade, but I'll let you know when I'm ready for another test.

Thanks!

Any chance of testing the Danger Den Delrin elbow with 1/2" fittings?

They are some nice looking elbows, but at $8/ea that's a little painfull for testing only unless I had a real need for them. My guess is they are just as restrictive if not a little worse because they are larger ID where it's threaded and there is some friction loss from the interior step up/step down.



Probably the best flowing elbow would be to take a piece of 1/2" ID copper tubing and bend it with a nice tight, but rounded sweep. Then take some needle nose plyers and flare out the ends a touch to provide some clamping resistance.??

Yeah cooper sweeps like that will work fine..You can buy cheap bending and flaring kits in hardware stores for $20 bux or so that have springs to slide down in the tubing so that when you bend it doesn't kink and most come with a little flaring tool so you can get a nice even lip on it...
