Noctua's NF-B9's highly-optimised blade design

After the successful introduction of the
NF-P12 120mm fan in November, Noctua presented today their first 92mm
retail fan: The NF-B9 complements Noctua's much acclaimed 80 and 120mm
fan series, which have been recommended by over 150 international
websites and magazines, and achieves outstanding airflow and pressure
performance at exceptionally low noise levels.
"Many avid Noctua users have already asked us for a 92mm model",
explains Mag. Roland Mossig, Noctua CEO. "After a development period of
over 18 months, we're finally able to present a 92mm fan that fully
meets our high demands and sets new standards in the 92mm range."
The NF-B9's highly-optimised blade design achieves an exceptional level
of airflow and static pressure that most other fans can only reach at
much higher speeds. For instance, the NF-B9 achieves no less than
64.3m³/h and 1.61mm H2O at 1600rpm.
Thanks to Noctua's advanced noise reduction techniques however, the
NF-B9 is surprisingly quiet at only 17.6dB(A): Bevelled blade tips and
the Vortex-Control Notches - already known from the successful NF-P12 -
minimize aerodynamic noise. Noctua's well proven SSO-Bearing as well as
the new SC drive system - already known from the NF-P12 - ensure
outstanding quietness and long-term stability.
The NF-B9 has an MTBF of over 150.000 hours and comes with 6 years
manufacturer's warranty. Using the supplied Low-Noise and
Ultra-Low-Noise adaptors, the fan's speed can be reduced to 1300 resp.
1000 rpm thus achieving even greater quietness.
