10w vs 18w DDC

[jibz]

Hey guys. I'm revising my build soon and I am currently using a 18w DDC pump which is doing a fantastic job but is unfortunately the loudest thing in my system. Would swapping it out for a 10w DDC be noticeably quieter or only marginally quieter for decreased performance?

10W DDC w/ the Sanyo DIYINHK would be the best thing to do. Or an MCP35X so you can easily drop the speed w/ PWM.

mcp35x at about 2k rpm is silent.
