Here is the miniNG set-up screen, for controlling the DDC + radiator fan:

DDC temperature readings are from the water (coolant) temp probe and RADIATOR from the CPU temp probe. As you may see, pump is starting @ 70% (8.4V) and not kicking in almost full speed until the coolant is really hot. One thing I noticed with the new 18W DDC-1plus as that I have to change the previous curve a bit, as pump is rather noisy (resonating) @ 60%. Another thing is that now I have the new rubber (antivibration) mounts for the pump (as you may see in the pictures above) ... so there is MUCH less noise even when it's running @ 100%. Proper pump mount is really a godsend. I don't find the new DDC much more noisy too. It's great pump in every aspect. As shown, radiator fan is also nicely silenced and dynamically speeding up over 30% only if the CPU/GPU temps are rising.

Here is the current flow rate with PC-ICE:

Before, with HydrX (just different coolant) was 8.4 l/min - 8.6 l/min

It looks like PC-ICE is more "dense", if that is the right term. I can even notice in the plexires less turbulence then before. Actually, you may notice in the green plexires version (from the above pictures) that there is evidently more turbulance.
