DDC ULTRA test @ H2okoeling.dk
Finally we got the DDC Ultra test online... 
Linky to Danish test
For those who can't read Danish (and shame on you  ) here is a mini translation of the review:
MaGiX, Jeppe Kamper Chief Editor, have done the full testing of it with the 3 tops below:
From the left AGB, PRO and Normal top
Notice the red impeller for the Ultra(18W) version, where the Normal (10W) has a black one.
We have used a our lab PSU to power the DDC Ultra. All testing done at 12 Volts
This shows that it draws 21.5 Watt (12vx1.79A =21.48Watt) and not 18W as rated.
Now the testing, here it goes 
DDC Ultra (18W) Basic

Please note the headline of the graph is wrong.
All DDC Ultra (18W) and DDC Basic (10W)
Pressure
Well, the DDC Ultra (18W) is a beast and is one of the best pumps (if not the best) for watercooling purposes.
I hope you enjoyed this mini translation and a full will follow at some point
Over and out for now

little confused by all the graphs, dont you have one comparing the three different tops with the 18w pump?

it looks like the pro top is the best one?

is it stating that there's diminishing performance with the added res top?

DDC Pro is still 10w version, so make sure label it as DDC Ultra to clear up the confusions, by the way very nice numbers there and can you enlarge inlet for testing and comparing?

Lol, my endless arguing that the inbuilt res kills performance finally vindicated! *opens champagne bottle*
Btw, they measured a max head of 17.43 feet with the unmodded AC top unlessmy maths has gone wonky.
And 11.241 ft on D5.
So although the absolute values are lower than Petra's results, the % differences are the same

Any info on when the shot of current draw was taken, max head/max flow (too low for startup obviously)?

You guys are killin me! 
Now my D5 doesn't look so good. 
@FairyDust,
How much impact will Dowfrost have over Dowtherm if I only use 1-2 oz. in a loop?
Thanks...

I'm fairly new to this forum so I don't know the full history, but I'm surprised you received that much resistance to this.
Anyway, although the res is obviously a performance detriment, I'm curious to know the actual impact of the res on temps in a typical loop. The results for the DDC+ with res are squarely between the DDC+ with top inlet and a D5 pump at most flow rates... implying that even with the res on the DDC+, its still a very very strong performer and would be more than adequate for almost any conceivable loop design.
I purchased the res with my pump before I knew all of this. I'm really inclined to go through the hassle of trying it in my loop and not to see the actual effect on temps. However, I'm curious in people's projections. Your thoughts?

I would really like to see consistent testing with the top inlet bored out to 9-10mm as well! Please consider this!

It seems clear to me... DDC+ = 18W version, DDC = 10W version... no?
Then the tops are: basis (stock), pro (plexi), AGB (plexi + res)

I know bro..
Oh well, I'll just use this until next year and upgrade new pump + rad.

now we need someone to compare dual in-line DDC's to a single RD-20/30. any takers?

Double the head figures.
So 17.41ft*2=34.82ft for dual DDC+ vs. 32.8ft for RD-30 @ 24v.
Pros of dual DDC+: slightly higher head, much lower heat dump, costs less!
Cons: lower max flow (so in-loop flow will probably be slightly lower), reliability (much like a RAID0 array youre statistically halving the MTBF by having 2 pumps)
Overall, the DDC+ is a superior choice for all but reliability freaks... and keep in mind Delphis are rated for 50k hrs MTBF, so the RDs are only worth it for freaks like me who plan to be using the same pump 8yrs from now

Yes, the AGB (Reservoir top) has dimishing performance...
When using the TOP INLET with the PRO TOP, the water flows more straight into the pump, which gives the better performance.

Well, the pump has so many names, so whatever you call it somebody will be confused...
I have put in a picture of the pump with it's respective top and then it results, which I hope can minimize any confusion...
We have done some testing by enlarging the inlet and outlet, which will be published at some point, by everybody around the site is pretty busy at the moment, so things are taking a bit longer than we want to...

We have purchased a MD-20 and 30 for testing and I have a MD-15, which will be tested at some point aswell

Well, it is a 12V pump, so it will be connected to your PSU...
So either overvolt your PSU or you could buy an external variable PSU, which you could control the voltage with...

The Pro top was not modified, is that correct? Really nice testing there. I'd love to see a comparison on the DDC+ with the modded and umodded top...

Thanks a lot!
That is correct. All testing have been done of the standard products. Modified testing will follow at some point...

Very nice testing. I also would like to see the modded vs unmodded top comparison along with using a radical top as well. The radical top and/or modded alphacool numbers are what most of us watercooling enthusiasts would be after.

Got a test on the way where I examine the effect it gives with drilling the top hole inlet and the front hole outlet up to 11 mm, and got the whole thing ready for launch, except for the diagrams for the test. As soon as they are ready, the test will launch.
The Radiical top I have tried to get my hands on for some time, I have tried to write to the Australian company, but got no reply… I am still very eager to get one of these home for testing, and will accept second hand products (as long as they stand in perfect conditions.)
If for nothing else, then for a week or two, and I’m fully ready to pay the shipment both ways as long as it comes from within EU…
If anybody got a spare Radiical top they can lend me for a couple of weeks, or interested in selling, then don’t hesitate, but contact me so this top can be a part of the test coming up in a short while…
But thanks to all for the nice words, glad the work we do are so appreciated
