Noctua NF-A8 PWM プリント
www.noctua.at
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 NE-FD1 IC 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.

Succeeding the award-winning NF-R8
Noctua’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 Channels
The 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 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.
from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment
and increases suction capacity, especially in space restricted environments.
Innner 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.

Low-Noise Adaptor
The 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.

SSO2 Bearing
The 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 durability.

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A8 PWM uses Noctua’s 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.

Extensive cabling options
The 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 fan to the same PWM fan
header for automatic control.
