+1 to that

What? No, that's the difference between the 3.25 and the 35X. 3.2vs3.25, you get a slightly more powerful motor overall, and due to that Laing rates it up to 20 watts instead of 18.

not exactly. 3.2 vs 3.25
There is some info that Swiftech 355 can have electronic components from DDC 3.15 and DDC 3.25 pumps. So i guess it a lottery

You can't say that they're the same just because he shows the same performance. There was a post there (now gone) detailing that it does have stronger magnets (or at least they're heavier), and from my POV Laing would NOT up the power spec for no reason. It IS a more powerful pump. Not to mention that a normal DDC 3.25 consolidates power and tach to one 3-pin connector instead of splitting it to a 3-pin and a molex.

all i wanted to say ,that mcp355 can be DDC3.25 too. and yes, ddc3.25 and mcp35x have PCB design differences.

I'm not sure what you are trying to get at. I think you missed a few things.

The 3.25 is a revision of the 3.2. It has a few changes. Bit it is still rated at 18W.
The PMP-400 on the other hand, which is a koolance revision to the 3.25, is 20W indeed.

Also from the consolidates power and tach talk, I think you are indeed talking about the PMP-400.
The PMP-400 top is different, which makes it a lot smoother, and they indeed decided to up the motor up to 20W. I'm not sure if there are any changes to the PCB or motor, but it could be, not ruling it out, but I doubt it.

There are no motor changes between the 3.2 and 3.25 and I didn't see any information which stated otherwise. It has a different PCB, which makes the power and how it works better, which gives the "effect" of it being a stronger motor, it coming with an original newer top.

The 35X is an evolution of these pumps, and its the best you can get right now.

No, it's not. http://lainginc.itt.com/files/LTBR-18.pdf

Koolance did not change the pump, at all. No revisions, no changes to the wiring or plugs, nothing. In fact you play a bit of a lottery (or at least you used to) when you buy a PMP-400; there's no telling if you'll get a DDC3.2 or a DDC3.25. The wiring will be a dead giveaway, though.

Everything about the MCP35x leads you to believe that it falls into the DDC family: size, shape, direction of flow, and the model number expecially. It's product name just makes it seem like a souped up MCP355 that they didn't want to call a MCP358, 359 or 360.

And I agree their support is not good. I was told that my Feser One had been the cause of my GPU blocks finish deteriorating. It was actually so bad that I bought new tops for the blocks because the plexi showing the inside and the inside looked like a rusting jungle gym.

To those who think the PCB is different, I'll let the picture do the talking...

I knew it had the same stuff underneath... I just wonder where they stuffed the function Martin mentioned back in post #13.
