Alright, I (unfortunately) have 2 Thermaltake Aquarius II water cooling systems. Since they are currently taking up space in my closet, I would like to use both of the pumps with the spare system I'm building, but I have a question. If I have this info correctly, 2 normal pumps (DDC, D5, Eheim, etc), when put in series, will double the head pressure at the same flow, and when put in parallel, will have the same head pressure with double the flow. Assuming that's correct, will that be the same with the Aquarius II pumps? The reason I'm asking is because each pump has a small built-in res. Just as some added info, the block I plan on using is the Koolance CPU-200G, and the CPU is a P4/3.06Ghz/800Mhz.
