I tried several fans on my SI-120 but in the end I settled for a Panaflo M1A. At full bore that thing is freaking loud but it cools the cpu and the entire mobo like no other. At 6v it is nearly dead silent and inside my P180 with my yate loon fans at 6v is completly inaudible from more than ~4ft.
If you don't have a fan controller a yate-loon/nexus or L1a are probably your best bets.

EDIT** For reference, my M1A @ 6v keeps my Opteron 165 @ 2.52ghz and 1.4v at 25-30c idle and 38-39c load.
