I've got a list going and I have one real question left to ask - bear with me as I talk it out firstly, I need help choosing a good pump, as so many places cite so many different ones that I'm going insane trying to comprehend it all! the components I would be using would be: D-Tek Fuzion V2 [cpu] EK Nickel FC4870X2 [gpu] ThermoChill PA120.2 [rad] Swiftech Microres [res] >> tubing of some nature, (tygon?) << but yeah; the only thing missing is a good pump that's going to be as quiet as possible really I'm so totally confused about all of the names for the Laing pumps, zaqwsx mentioned a DDC v5.4 which totally throws me as I can't find it anywhere! is this a DDC350/55? it looks the same, but I know that's not always to say they ARE the same...lol so yeah; "DDC v5.4" or D5 or DDC350/55...I'm so confused.. also, will I see any damage caused by the weight of the 4870X2 waterblock?
