Can I use this pump? And how?

I have been looking into water cooling lately, and have considered getting a complete kit with a 360 radiator.

Then yesterday one of my friends were stripping an old Mac Pro G5 (for the case), when I noticed it was a water cooled version. I stripped the pump from the rig, since I recognized it from my readings around the intrablag.

On the pump it says Delphi, and on the side it says "Type: DDC-1VC, DC12V 10W". Here are some pictures:

So, my concerns are:

How do I power the pump? The 4-pin connector is unlike anything I have seen before?
Is the pump powerful enough for a 360 radiator?
The pump is at least 6 years old - should I be concerned about it wearing down? Any way to test the pump by itself?

That pump looks really familiar. Maybe an older version of this. I think I've seen a similar design elsewhere, but it has been at least 3 years since I looked into water cooling.

Too risky for my taste. Buy a new one.

That looks like a Laing DDC/MCP350 with some sort of base attachment. 6 years is a bit old for the pump, but it's probably got at least a year or two left in it, if not more. I would take the pump apart, and post some pics. If you have the blue impeller version (which is likely since it is so old), you can mod it to a MCP355.

As for the connection, two of those are definitely power connections, and one is an RPM sensor. I'm not sure what the last would be used for. Maybe taking apart the pump could help, as we can take a look at the PCB.

That pump, if it is indeed what I think it is, will be powerful enough for most systems (2 waterblocks, one or two radiators). If you can mod it, then it'll be powerful enough for at least 3-4 waterblocks and 2 radiators. Getting a custom top for it would also definitely improve performance, like the XSPC res-top.

Its a DDC1 which means it will have a black impeller and no modding is possible unless the board is replaced.

You can use the pump no problem. Just replace the connector on there and you are good to go.

Standard MCP 350.
They are all made in hungary.

This was just some OEM modification of the standard swiftech models.

The wires are most likely identical to the standard Molex arrangement, one of them would be an RPM sensor most likely.
would require cut and soldering.

Depending on what you paid....I'd probably just buy a new MCP 355 and pump the XSPC reservoir top on it.

It should work fine, it's a standard DDC1 (aka MCP350). It's got the volume compensator on it which apparently is supposed to adjust for pressure in a closed loop. To power it you'll need to re-pin it to a standard 3-pin.

re-top, re-connectorize, clean, and roll with it, most of those old G5's have only a few thousand hours out of the 50,000 it's rated for.
