Since the DDC pump has become so popular and now is generaly always recomended over the D5 and 50Z(wich also are very good pumps), that is with the modifed tops of course, ive decided to collect all info about the pump in one thread.
DDC is known to be more silent than both D5 and 50Z while it outperform them both!
The pump is known under different names and there may be a little confusion out there since there also is a couple of different version of the pump. Ive collected the names beneath... There is also a 11W version but its the 10w\18w wich is normal and being sold now so i consentrated about them:

There is now a new revision out wich has a blue impeller with a bit smaller hole in it. The layout of the pump semes to be the same for both ddc1 and ddc2 so both can potensially be changed to the other. Read more Here(german)

Different 10w names(with and without tops): ddc-1, mcp350, ddc pro,
Different 18w names(with and without tops): ddc-2, mcp355, ddc ultra, ddc+, ddc 1t-pluss

The pro and ultra is actually alphacool names and describes the 10w and 18w with their top

How to spot the difference between 10w and 18w:
10w got a black impeller and 18w got an orange impeller
There is also some holes in the impeller of the 18w but if you spotted those youve already noticed the orange color of it ;)

Aslo added some places to buy this pump, there is ofcourse a lot more but here is some atleast

Warning! There seemes to be som fake ddcs going around!

And this pump doesnt show its real beast without a modded top. the top is what really makes this pump
and you can read some of this tests to see why and how well it performs

Tests:
Petras test of Petra\Alphacool\Radiical tops, also including 50z
H2Okoelings test of standard\alphacool\water tank top(danish)
Systemcoolings test of 10W

The Alphacool\watercool tops can even be modified a bit for a little more performance, its just about enlarging the inlet hole as is a little small
original. Just remember not to over do it as bigger aint always better :)
Here is a few links to people @ xs who modified theirs:

Andersson.j
Trice

Here ive listed every top wich is avaliable, except from the originale of course

Different tops:

There is also been some pumps with starting issues, you can discuss it more
Here

I have studdyed these a lot as i need 7 in my rig!

Hope this help guys
