Possible to mod a DDC-1VC 10w to 18w?

[almighty15]

Just got my hands on some black impeller DDC-1VC's and was wondering if it's possible to mod them to 18w like you can on the newer versions.

PCB is version D1 and D2, PCB also has DDC v5.4 printed.

Any help or diagrams would be awesome :)

Not that I know of, I think they might have different windings.

Only thing I think you can do is over-volt them a bit. They didn't start voltage protecting them until the DDC3 series so they will be happy to start at 14V or more. I once ran 30V through a DDC2...boy did she fly for a few seconds there then PooF! out comes the blue smoke..:D

Due to all of the confusion regarding the naming of the DDC pumps (and Laing selling them in all sorts of configurations), a quick photo of the bottom of the PCB would tell us pretty much everything we need to know.

That said, if it's one of the original DDC-1 pumps, then the answer is no.

You can get a little more power by swapping out to a Toshiba based DIYINHK pcb:

Here is that one I tried:

But for cheap, I would just buy a NOS DDC1 from Bmaverick and run two in series:

At $35 shipped, that's pretty hard to beat anywhere.

I think he's got a few spares on hand still...:eek:

I have his Sanyo-DDC running for almost 1 year. The best pump I ever had. And what is more: this pump runs - connected to Aquaero 5 - even with 4 Volts (= ~1020 rpm!) without problems. From absolute silence up to nice power everything possible.

How effective would two of these be in a XSPC Dual Bay Reservoir for two DDC Pumps? I am thinking of having them both running in one loop. Would provide some redundancy. For now, the loop would include a PA 120.2 and Apogee XT. Might upgrade the rad to a three fan rad and add in a XSPC Razor on my GTX 590.

A DDC1 with top is pretty close to a D5 Setting 4.5 or so, still a pretty strong little pump. Two in series is a lot more power than most single pump setups. Great pumps, but a touch more noisy than DDC3.1s.
