Screws Flow Acceleration Channels The NF-A4x10 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 Reduced Motor Hub Size Thanks to its
streamlined, compact motor design, the NF-A4x10’s motor hub is
smaller than with conventional 4cm fans. This allows for more blade
surface area and thus contributes to the NF-A4x10’s superior
airflow and pressure performance. 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. Smooth Commutation Drive 2 The latest version of
Noctua’s advanced Smooth Commutation Drive system ensures superb
running smoothness by eliminating torque variations and switching
noises. This makes the NF-A4x10 remarkably quiet even at very close
distance. button SSO2 Bearing The NF-A4x10 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
Low-Noise Adaptor for full flexibility The NF-A4x10 FLX
(Flexibility) is supplied with a Low-Noise Adaptor (L.N.A.) that
reduces the maximum fan speed from 4500 to 3700rpm so that it can
be fine-tuned for superior airflow or maximum quietness. 3 to 2-pin
Adaptor and Polarity Protection The NF-A4x10 comes with an adaptor
from 3-pin Molex to the 2-pin connectors used on many graphics
cards or network and storage devices. An integrated diode provides
polarity protection on 2-pin connections. OmniJoin Adaptor Set Many
devices featuring 40mm fans use proprietary fan headers, so the
NF-A4x10 comes with Noctua’s OmniJoin Adaptor Set. Just cut the
original fan’s cable, fix it to the adaptor using the supplied 3M
Scotchlok™ connectors and you can plug the NF-A4x10 to proprietary
fan headers! button 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.
