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

Here there are specifications:

Blade Geometry: Straight-Blade-Design
Rotational Speed (+/- 10%): 1200 RPM
Rotational Speed with U.L.N.A. (+/- 10%): 600 RPM
Airflow: 81 m³/h
Airflow with U.L.N.A.: 41 m³/h
Acoustical Noise: 17 dB(A)
Acoustical Noise with U.L.N.A.: < 6* dB(A)
Input Power: 1,44 W
Input Current: 0,12 A
Voltage Range: 4-13 V

Box contains:
1 Ultra-Low-Noise Adaptor (U.L.N.A.)
4 Vibration Compensators

*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!
