Noctua unveiled a new silent fan, the NF-B9, this is their first 92mm model.
"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.
