Award-winning NF-A9 design
Having received dozens of recommendations from the international
press, Noctua’s NF-A9 has become a proven premium choice for
92mm cooling needs. Its renowned efficiency has convinced tens
of thousands of customers all over the world.
chromax.black.swap edition
Maximising colour choices, Noctua’s chromax.black.swap edition
fans can be colour-customised using the included swappable
anti-vibration pads as well as optional anti-vibration mounts
and cables. This makes them ideal for enthusiasts looking for
true premium-grade fans that can be colour-coordinated with
popular build themes such as all black, black & white or black &
red.
Swappable anti-vibration pads in 6 colours
The NF-A9 PWM chromax.black.swap comes with 4 white, red, blue,
green and yellow as well as 8 black NA-AVP5 anti-vibration pads.
By combining the various colours with black or going all black,
the fan can be coordinated with most popular build colour
schemes out of the box. Additional NA-SAVP5 sets for outfitting
both sides in one colour can be purchased separately.
Optional coloured cables
Noctua’s chromax line fans use a modular cabling system and come
pre-fitted with a fully sleeved black NA-EC1 30cm cable. For
refined colour coordination, white, red, blue, green and yellow
30cm NA-EC1 cables plus corresponding NA-YC1 y-cables are
available separately.
Optional coloured anti-vibration mounts
To complement the coloured anti-vibration pads included with the
fans, users can purchase chromax line NA-SAV2 anti-vibration
mounts that enable the convenient, quick and vibration-free
installation of fans in standard mounting holes for case fans.
Flow Acceleration Channels
The NF-A9 impeller features suction side Flow Acceleration
Channels. By speeding up the airflow at the crucial outer blade
regions, this measure reduces suction side flow separation and
thus leads to better efficiency and lower vortex noise.
AAO frame
Noctua's AAO (Advanced Acoustic Optimisation) frames feature
integrated anti-vibration pads as well as Noctua's proprietary
Stepped Inlet Design and Inner Surface Microstructures, both of
which further refine the fan's performance/noise efficiency.
Stepped Inlet Design
Noctua's Stepped Inlet Design adds turbulence to the influx in
order to facilitate the transition from laminar flow to
turbulent flow, which reduces tonal intake noise, improves flow
attachment and increases suction capacity, especially in
space-restricted environments.
Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary
layer created by the Inner Surface Microstructures, flow
separation from the suction side of the blades is significantly
suppressed, which results in reduced blade passing noise and
improved airflow and pressure efficiency.
SSO2 Bearing
The NF-A9 features the further optimised second generation of
Noctua's renowned, time-tested SSO bearing. With SSO2, the rear
magnet is placed closer to the axis to provide even better
stabilisation, precision and durability.
Custom-designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A9 PWM uses
Noctua's novel, custom-designed NE-FD1 PWM IC that integrates
Smooth Commutation Drive (SCD) technology. By providing smoother
torque impulses, SCD suppresses PWM switching noises and thus
makes the fan quieter at low speeds.
Stops at 0% PWM
When the fan is set to 0% PWM duty cycle by the motherboard or
PWM fan controller, it will stop. This makes it ideal for
creating setups with semi-passive cooling that automatically
turn the fans off and thus run completely silent at idle if
thermals allow.
6-year manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and
outstanding longevity. Like all Noctua fans, the NF-A9 features
an MTTF of more than 150.000 hours rating and comes with a full
6-year manufacturer’s warranty.
