They're older. Probably produced before 2008.
They're about as powerful as the later versions.
They generate more noise.

That's strange. It's pretty common knowledge that flow over 1-1.5gpm is has shown little gain in in regards to loop cooling.

It has taken Martin's reviews to establish that in the WCing community here.

As for the Laing DDC-1 and the MCP350, originally, Swiftech sold them right out of the shipping crate that Laing had sent them. Then, a few months later, Laing added the flat area on the top of the pump so Delphi, DD or Swiftech could place a sticker on the pump. When the orange/red/blue impellers came out, Laing started making the pumps customized to each company. Swiftech is primarily a distributor house of WCing gear that has their brand name on stuff or an exclusive build for Swiftech by another company. Swiftech does not have the captial funds to be a manufacture. It's own stock has fallen flat on it's face twice in the 2000s.

Yes Martin's reviews do show diminishing returns with increased flow rate above ~1.5 gpm. However I can't recall ever seeing a test where the temperature increased after a certain point.
In any case look at the PCB and see if it can be modded into an 18W. If not I can say from experience that a loop with a Swiftech XT, an Aquagrafx on my 470, a GTX240, and a MCR240 didn't see significantly improved temperatures moving from a 350 to a 35X. Higher speed fans had much more of an impact.
