What did you have in there before?

If you want quiet, go with an Eheim 1048, foam mounted in case, with the impeller modified as per BeerHunter's suggestion at OCF (can't find link at the moment). For DC pumps, the closest thing to quiet would be the Laing DDC, or perhaps even the Laing D5 dialled down to the #1/2 positions if you need 1/2" compatability. Again, foam mounting to prevent pump vibration is the largest single source of noise that generally occurs in most "quiet focuses" WC setups.

You want quiet for fans, you simply cannot go past the Yate-Loon's, which get rebadged as Nexus and sold with a resistor to slow them down to 1000rpm (1350rpm as stock). Quietest 12cm radiator fans about, period.

For mosfet cooling, I just have a "Wherever PCI Rack" installed in my case, and use a Yate-Loon spinning lazily to provide additional cooling to the mosfets, NB (passive) and memory.
