My new low noise chassis fan: Noctua

Today I bought a new fan to make my 2 Raptor HDs ready for hot summer :)

I think I paid it a lot: 21,90 Euros, but I’m very happy: I wanted an ultra silent fan and I have it! :) It is a: Noctua NF-S12

*extrapolated values

I haven’t installed the U.L.N.A. because I want maximum airflow, but I think that with the adaptor it will become really inaudible!
