As another ditto to BillA and airspirit, these magdrive pumps degrade very quickly as flow restriction is placed upon them. This is the main reason I have not done any NB or GPU watercooling yet with my single pump system. Those blocks add so restrictiction that my CPU cooling would be seriously compromised. If I ever watercool my GPU, PSU and NB, I'd use a separate pump because trying to cool all those things with a single Eheim 1250 would be like trying to drive a large car at 5mph when in 5th gear. You might get some movement, but it would make a lot of noise trying to do it.

Listen to BillA and airspirit. They know what they are talking about.

Has anyone used a different type of pump like a peristaltic or positive displacment pump? I don't know much about their flow rate, MTBF, efficiency or noise level, to be honest.
