Noctua today introduced its new NF-A14 FLX,
NF-A14 ULN and NF-A15 PWM 140mm fans that complement the recently
announced A-series of premium quality quiet fans. Like the previously
presented NF-A4x10, NF-A6x25 and NF-A9x14, the new 140mm models feature
Noctua's novel AAO frames as well as the series' signature Flow
Acceleration Channels for reduced boundary layer separation and improved
aerodynamic efficiency. Reference class SSO2 bearing and 6 years
manufacturer's warranty make the NF-A15 and NF-A14 a stand-out choice
for all noise-sensitive 140mm applications.
"Introduced in 2009, our NF-P14 has become a default-choice among PC
enthusiasts looking for a premium quality, quiet 140mm fan, so we're
excited to further improve its much acclaimed airflow to noise ratio
with the new NF-A14 and NF-A15", says Mag. Roland Mossig, Noctua CEO.
"The A14 and A15 models all sport the key features of our new A-series
fans and now come in both round and square frame design."
Whereas the NF-A15's round frame features 120mm mounting holes (105mm
spacing) and has been enlarged to a width of 150mm in order to provide
superior performance on today's high-end CPU coolers, the NF-A14 models'
square shape and 140mm mounting holes (124.5mm spacing) make them ideal
for use on watercooling radiators or as an upgrade for 140mm case fans.
Tailor-made for use on CPU coolers, the NF-A15 PWM comes with Noctua's
custom designed NE-FD1 PWM IC for fully automatic speed control. The
NF-A14 comes in FLX and ULN versions with 1200/1050/900 and 800/650
speed settings for full flexibility in quiet to ultra-quiet case and
Like all new A-series fans, the NF-A15 and NF-A14 use a novel
aerodynamic design measure called Flow Acceleration Channels that allows
them to significantly improve the airflow to noise performance of
conventional, uniform blade shapes. By speeding up the airflow at the
crucial outer blade regions, Flow Acceleration Channels reduce suction
side flow separation and thus lead to better efficiency and lower vortex
All three fans employ the further optimised second generation of
Noctua's renowned, time-tested SSO bearing as well as Noctua's AAO
(Advanced Acoustic Optimisation) frames that feature integrated
anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design
and Inner Surface Microstructures, both of which further refine the
fans' performance/noise efficiency. Like all Noctua fans, the NF-A15 and
NF-A14 have an MTBF rating of more than 150.000 hours and come with a
full 6 years manufacturer's warranty.
