I finally got it hooked up. Havn't tested any of the meters for accuracy, but it does work nicely.

Had to make a few custom fittings to test in style though. Excuse the test bench while I tinker. Going to have to build a nice stand for the flow rate meter and digital manometer.

Anhow, here is a few pics:


The custom pressure drop fittings...mother of all style. In testing with just the fittings and a 2" piece of tubing, I had less than 2" of pressure drop at 3 GPM....that's very good..almost nothing.



A little Fuzion with 4mm nozzle testing:






I couldn't get above 1.4GPM without pegging my 200 in manometer max, that's much more pressure than a D5 or DDC can produce..

And my uncalibrated, unchecked, results:

That's alot more restrictive than I expected...hmmm

I'll have to run a few known curves and see how they compare, then do some calibration checks on the flow meter and digital manometer.

I need to find the nozzle curves, I thought I saw them somewhere..?

Very interesting. Awesome work mate!

Thanks!
Made a few more runs:

Fuzion runs with a comparison to D-Teks published curve:


MCW-60 curve with a comparison to Swiftech's published curve:


It is SOOOOO much faster doing these with the new tools, and I'm feeling pretty confident of the results now.

Things I noticed:

D-Teks curve appears to match my test with a washer. It's funny they tested and posted results of a stock fuzion "With" a washer, but then they don't provide one as the "Boxed" kit.

The popular 4.5mm nozzle is "EXTREMELY" restrictive, most restrictive curve so far, so you probably don't want to run a nozzle in a multiblock loop.

Hey how did I miss this...That 4.5mm nozzle just about puts it into jet impingement territory doesn't it...Does it seem to cool well with that nozzle? Just wondering if the base pattern takes advantage of it...I guess it would or they wouldn't of made one that size......

Nice T's going on there Martin.......Nice set-up to, thats got to beat climbing ladders all to pieces......The testing looks great as always, its very informative to see actual hands on testing instead of theory...Good job Man...

You not kidding...I think I cut my time to make one curve down to 1/10th the amount of time, and so far it's looking more accurate and precise too. I think one of the big advatages of the nozzle is eliminating the dead spot in the center. After seeing Burn's picture of the gunk he had to clean out, it really pointed out that the very center doesn't get very much flow at all without a nozzle...just sort of a cone of water sitting there trapped in the pinswhile all the water runs around the perimeter of the 3/8" inlet. If you make that inlet a very small hole using a nozzle, then it takes care of that problem.

Anyhow, I havn't actually completed thermal testing on these commercial nozzles, but I do know they are very very restrictive when running the washer as well. Most people think they still flow well, so it's a bit hard to swallow for some just how restrictive it is. It's actually more restrictive than a Storm, or any block for that matter. In the end it doesn't really matter what your flow rate is if it gives you better temps on a CPU only loop, but I'd think twice about running a nozzle kit if it were a CPU/GPU loop....were talking 1 to 1.2 GPM max territory for a D5 or DDC powered loop.

And yes....No more ladders for me...

Yeah really if your into OC'ing you'll put as big a pump behind a CPU block as you need as long as it cools well....I forgot about Burns gunked up Fuzion he did have a dead spot didn't he.....So basically all they are doing in covering their rear with a fix for a design mistake...To give them credit though it worked pretty well with-out nozzles anyway...I should say they refined their design.......


WOW..Its more restrictive then a Storm or a MP-05 with a 4.5mm nozzle, that takes some doing...Look forward to seeing more of your testing....
