So size and potential longevity aside, are there significant performance differences between the new D4/mcp650 and this new DDC?

From their respective specs (DD + Swiftech):

D4/MCP650 (muffled version):
Maximum flow @ 12 volts = 5.28 GPM
about 0.9GPM @ 8 feet
max head = 10 feet H2O

Laing Delphi DDC:
Maximum flow @ 13.5 volts = 1.75 GPM
about 1.15GPM @ 8 feet
max head = 14.5 feet H2O

I suppose the maximum flow rates are given for 0' head.
I would like to see both pumps in the same graph...

Yeah, on the interactive graph maybe. Hey, what happened to that?

edit: found it. I incorrectly recalled it being for pumps AND blocks http://www.procooling.com/html/pro_testing.php
Now that would be nice (hint hint).

Now what is the curve going to look like at 12V? I know my PSU only puts out 12

This seems to be the pump for switching back to 3/8" tubing and plumbing GPU, NB, CPU, etc all in series...

swapping the DDC for the MCP650 in a small system with a MCR120 and MCW6000 saw the flow rate drop 0.05gpm with ~+0.15° at the die

it was quite a trick to get the pump running, not at all what we figured here

have to say that this pump is extraordinary for its size and output
but not cheap, nor dead quiet

Will the DDC come in 1/2" flavor? Have you done DDC vs. mcp650 testing with the mcw50 in the loop?

movement is glacially slow, but continues
the MCP350 (aka Laing DDC) P-Q curve @ 12VDC (courtesy of Laing)



no more info until the pump's release, sorry
other vendors to be considered

Damn, that's some impressive flow rates! Maybe change the name to MCP21000?

Groth, did you read "GPH" instead of "LPH"?

That is kind of strange. From looking at the pump curves, that implies a pressure drop in the system of around 8-10 feet which seems high.

What do you mean by not dead quiet?

Alright so here's a new graph with the 12V info that Bill provided. It also has an interpetation of Bill's test system, it has a 3 gph drop from MCP650 to MCP350.

Look on HardOCP front page, I think it clears ANY doubts about what kind of pump Apple is using.

wow..... a pump that small with flow rates like that. Delphi must've invested quite some time and money into this little pump, especially since it's going as a stock cooling system into an Apple.

I looked all over this thread and the website for the pump, then finally decided to mess with the urls and found it
http://www.lainginc.com/DDC_Series.htm

D4 for $75 or DDC for $105, I think I'll take the D4. It must be so expensive because it's associated with Apple.

Public price isn't reseller price and with large quantity this pump will be cheaper...
