Noctua presents NF-B9 92mm fan

[Spawne32]

Vienna, February 6th 2008 - 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.

Price and availability
The NF-B9 is available immediately at a recommended price of EUR 17.90 / USD 21.90.

If I did my math right that's 109.2 CFM. Very impressive for a 92mm fan, especially with a 6 year warranty. Only problem I see is that it claims 17.6dB at the highest speed. There's no way 109.2 CFM of air can sound that quite. That's going to be a loud woosh.


EDIT!!: I did do my math wrong. This is roughly 38 CFM. Not that impressive in my opinion.

Looks like a combination of the P and the S series. :)

And it's rated for 37.8CFM, not 109.2 :p:

Yes, yes. Simple conversions are beyond me! I got all excited thinking there was a new Vantec Tornado on the block, but with a 6 year warranty! :p:

140mm>92mm

I might be stating the obvious but...

That's the understatement of the year.


Anyhow, it's good to see that Noctua is recognizing the importance of static pressure in fan design. The S-Series fans looked great on paper, but that's about it.

I may pick one of these up to go on my HR-03!!

Do want good 140mm fans. On a totally unrelated note, how's fan roundup 3 (:the sequel) coming along Vapor?

lol it looks like they've stuck with the hub of a larger fan

It takes less to design space shuttle :D

I very much doubt that. Most modern aircraft development cycles are rather lengthy, the average being about 5 years to go from prototype to production. Of course, NASA would probably be happy with the first prototype that works, but I imagine it would still take longer than 1.5 years.

so expensive for a FAN...
