hey guys, ive been doing some research on these DDC pumps by laing. I myself have a koolance PC3-700 case with the upgraded pump/tank (specifically the TNK-400-NX2SL).

i am fairly certain that this '18w' pump is the same as the DDC+ or DDC2 pump you all are talking about here. can anyone confirm that at all? im just wondering because my pump is not quiet at full speed (i have the pump speed controller from koolance as well, nifty little gadget to have when i sleep!).\

i know koolance is highly NOT recommended but it was a gift to me last year and i dont have the option to make a new system (yet), so please just bear with me here!

take a look here or here for the pump/res im talking about. the 2nd link's 'more pictures' show a good view of the orange impeller already mentioned in this thread, just FYI.
