špičky - bevelled blade tips), innovativní samostabilizující
olejové ložisko.
14mm Low Profile Design
Measuring only 14mm in thickness, the NF-A9x14 is much slimmer than
standard 92x25mm fans. This makes it ideal for all applications
where standard fans would take up too much space, such as low
profile CPU coolers in HTPC builds or server environments.
Flow Acceleration Channels
The NF-A9x14 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. button
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. button
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. button
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. button
Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone
minimise the transmission of minute vibrations while maintaining
full compatibility with all standard mounting systems and fan clips
used on heatsinks.
SSO2 Bearing
The NF-A9x14 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. button
Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A9x14 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 lower speeds. button
Low-Noise Adaptor
The NF-A9x14 is supplied with a Low-Noise Adaptor (L.N.A.) that
reduces the maximum fan speed from 2200 to 1700rpm. The L.N.A can
be used either to run the fan at a fixed speed of 1200rpm or to cap
the maximum speed when using automatic PWM control.
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 NF-A9x14 fan to the same
PWM fan header for automatic control.
