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....
