Noctua presents NF-R8 fan
 
Vianna, October 24th 2006 - After the successful introduction of the
NF-S12 in August, Noctua expands its range of premium quality fans with
the NF-R8 80mm fan. Like the NF-S12, the NF-R8 employs a novel rotor
developed by the Austrian Institute for Heat-Transmission and Fan
Technology (Österreichisches Institut für Wärmeübertragung und
Ventilatorentechnik, ÖIWV). Thanks to the special optimisation of the
blade geometry towards ultra low noise application and Noctua's
magnetically centred, self lubricating oil-pressure bearing (SSO
bearing), the NF-R8 is up to 10% quieter than other high-end fans at the
same flow rate.

"Many satisfied NF-S12 users have asked us whether there is an 80mm fan
with similar qualities", reports Mag. Roland Mossig, Noctua CEO, "After
more than two years of development, we are extremely happy to be able to
provide an innovative top-quality product in the 80mm range too!"

The NF-S12 120mm fan introduced in August has earned more then 20 awards
and recommendations from leading international websites and magazines.
Like the NF-S12, the NF-R8 employs a novel rotor developed by the
Austrian Institute for Heat-Transmission and Fan Technology
(Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik,
ÖIWV). Its Raised-Blade-Design provides a significant boost in
efficiency compared to conventional rotors at low rotation speeds.

"In order to make their products more silent, fan manufacturers usually
simply reduce RPM without adapting the rotor design to the modified
fluid dynamic parameters", explains Mag. Manfred Stadler MBA of the
Austrian Institute for Heat-Transmission and Fan Technology. "Using a
blade geometry specifically optimised for lower speed ranges like the
Noctua Raised-Blade-Design allows for much better performance than
simply reducing RPM."

Running at 1800rpm, the NF-R8 provides a flow rate of 53m³/h at a noise
level of only 17dB(A). Using the supplied Ultra-Low-Noise adaptor, the
noise level can be reduced below 7dB(A)*.

Like the NF-S12, the NF-R8 is equipped with a magnetically centred, self
lubricating oil-pressure bearing (SSO bearing) that surpasses current
types of ball-, sleeve- and liquid bearings in long-term stability and
quietness thanks to its new, improved principle of operation. The NF-R8
has a MTBF of over 150.000h and comes with 6 years warranty.

The scope of delivery of the NF-R8 includes a Low-Noise-Adaptor (L.N.A.)
and an Ultra-Low-Noise adaptor (U.L.N.A.) that allow for a further
reduction in noise emission, 4 vibration compensators for vibration-free
installation as well as a 3:4 pin adaptor and 4 fan screws.

Technical specifications
Detailed data, photos and background information on the Noctua
Raised-Blade-Design and the SSO bearing can be found at www.noctua.at.

Prices and availability
The NF-R8 fans will be available by November. The recommended retail
price is EUR 14.90 /USD 18.90.
