No improvement for me.
none for me either using quad nozzle and mx2
hmmm seeing no improvement at all seem's strange...hopefully i see some improvement....
No noticeable temp changes. My cpu is pushed to the absolute limit that I doubt its even prime stable. Idles are 44,44,36,37. Multiple mounts still the same. I guess two cores are being worked harder than the other two. Those were pretty much the same temps as before. Load is around 70 for all 4 cores fans on full blast. Temp improvements within 2 degrees or so can be so easily swayed by ambient temps. Save ur money and get better fans.
Well I just installed the 3.5mm nozzle. All I can say is WOW! Holy flowkiller Batman! MUCH more restrictive than the 4.5mm... I can honestly say there is really no reason to use the 3.5mm at this point. I haven't officially run it on the test bed but judging by the flow killage with 2 DDC-2's in series I say best to stay away. Cathar funny enough mentioned that ~4.7mm is optimal. This is all on a dual core FWIW.
I noticed that as well. I had a hard time telling if the water was even flowing at all. I'm wondering about the nozzle diamater all together. The nozzles I have measure just over 4mm and just over 5mm diamater. Definately not 4.5 and 5.5
Do you know where the measurement is taken from? If cather says 4.7 is optimal, I'd love to try and open up the 3.5 to measure 4.7 since I won't be using the 3.5.
There is a 3.5mm nozzle which is the smallest, the next size up is 4.5mm.
I will take a 4.7mm nozzle for my 1/2" FuZION low-flow DDC-01 setup and document the test bed for you.
Once I fix the Liang MCW350 that leaks in two places :(

Is the o-ring in there?
Looks like a PTS head that's not tight enough or has it's o-ring left in the stock top.
before I had the nozzles load temps were 53C on core 0 and 2 and cores 1 and 4 would fluctuate between 53 and 54C and I did 4 mounts and were getting roughly the same temps each time. but after I installed the Quad Nozzle I'm getting 51C on all cores so a improvement for me.
btw i'm using Arctic Ceramique
I did some more acurate measuring and you're right. No matter, I installed the 5.5 just to see the difference and the temps are actually worse than the 3.5 with all its resriction. Could be a bad mount, but either way I'm going to take the block apart one last time, put the 4.5 in and call it a day.
This shows the o-ring I mentioned.

It sits between stator and top. Can stick to the top and be missed during re-assembly with a new top.
Indeed it was there, thanks a million -- disassembling now.

and I will let the stator dry out for about 6 hours (even though the pump is submersible) before I run it again in my test loop.

2c is pretty good imo...
