Вентилатор Fan 80mm NF-A8-PWM product


The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels,
the NF-A8 further improves the renowned quiet cooling performance of
the award-winning NF-R8. The PWM version sports Noctua’s custom designed
for fully automatic speed control via 4-pin fan headers and comes with
a Low-Noise-Adaptor to reduce the maximum speed during PWM control from
2200 to 1750rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.Specifications

Succeeding the award-winning NF-R8Noctua’s
NF-R8 fan has become a default-choice among PC enthusiasts looking for a
premium quality quiet 80mm fan. Thanks to its thoroughgoing aerodynamic
optimisations, the NF-A8 provides higher static pressure and an even
better airflow/noise ratio than its much acclaimed predecessor.

Flow Acceleration ChannelsThe
NF-A8 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 FrameNoctua’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 DesignNoctua’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 MicrostructuresWith
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.

Integrated Anti-Vibration PadsIntegrated
Anti-Vibration Pads made from extra-soft silicone minimise the
transmission of minute vibrations while maintaining full compatibility
with all standard screws and other mounting systems.

SSO2 BearingThe
NF-A8 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

Custom designed PWM IC with SCDSupporting
fully automatic PWM speed control, the NF-A8 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.

Low-Noise AdaptorThe
NF-A8 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces
the maximum fan speed from 2200 to 1750rpm. The L.N.A can be used either
to run the fan at a fixed speed of 1750rpm or to cap the maximum speed
when using automatic PWM control.

Extensive cabling optionsThe
fan’s short 20cm primary cable minimises cable clutter in typical
applications while the supplied 30cm extension provides extended reach
when necessary. Both cables are fully sleeved and a 4-pin y-cable allows
to connect a second NF-A8 PWM fan to the same PWM fan header for
automatic control.

6 years manufacturer’s warrantyNoctua
fans are renowned for their impeccable quality and outstanding
longevity. Like all Noctua fans, the NF-A8 features an MTBF of more than
150.000 hours rating and comes with a full 6 years manufacturer’s
