\n \"5V <\/div>\n
\n

5V version<\/h1>\n
\n

Many devices such as network or storage solutions use 5 volt 40mm fans.
\nWith the same operating voltage and the included OmniJoin\u2122 adaptor set
\nthat makes it compatible with proprietary fan headers, the NF-A4x10 5V
\nis ideal for replacing noisy or broken 5V 40mm fans.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Flow <\/div>\n
\n

Flow Acceleration Channels<\/h1>\n
\n

The NF-A4x10 impeller features suction side Flow Acceleration Channels.
\nBy speeding up the airflow at the crucial outer blade regions, this
\nmeasure reduces suction side flow separation and thus leads to better
\nefficiency and lower vortex noise.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Reduced <\/div>\n
\n

Reduced Motor Hub Size<\/h1>\n
\n

Thanks to its streamlined, compact motor design, the NF-A4x10’s motor
\nhub is smaller than with conventional 4cm fans. This allows for more
\nblade surface area and thus contributes to the NF-A4x10’s superior
\nairflow and pressure performance.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"AAO <\/div>\n
\n

AAO Frame<\/h1>\n
\n

Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated
\nanti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design
\n and Inner Surface Microstructures, both of which further refine the
\nfan’s performance\/noise efficiency.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Stepped <\/div>\n
\n

Stepped Inlet Design<\/h1>\n
\n

Noctua’s Stepped Inlet Design adds turbulence to the influx in order to
\nfacilitate the transition from laminar flow to turbulent flow, which
\nreduces tonal intake noise, improves flow attachment and increases
\nsuction capacity, especially in space-restricted environments.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Inner <\/div>\n
\n

Inner Surface Microstructures<\/h1>\n
\n

With the tips of the fan blades ploughing through the boundary layer
\ncreated by the Inner Surface Microstructures, flow separation from the
\nsuction side of the blades is significantly suppressed, which results in
\n reduced blade passing noise and improved airflow and pressure
\nefficiency. <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Integrated <\/div>\n
\n

Integrated Anti-Vibration Pads<\/h1>\n
\n

Integrated Anti-Vibration Pads made from extra-soft silicone minimise
\nthe transmission of minute vibrations while maintaining full
\ncompatibility with all standard mounting systems and fan clips used on
\nheatsinks. <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Smooth <\/div>\n
\n

Smooth Commutation Drive 2<\/h1>\n
\n

The latest version of Noctua’s advanced Smooth Commutation Drive system
\nensures superb running smoothness by eliminating torque variations and
\nswitching noises. This makes the NF-A4x10 remarkably quiet even at very
\nclose distances.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"SSO2 <\/div>\n
\n

Cuscinetto SSO2<\/h1>\n
\n

The NF-A4x10 features the further optimised second generation of
\nNoctua’s renowned, time-tested SSO bearing. With SSO2, the rear magnet
\nis placed closer to the axis to provide even better stabilisation,
\nprecision and durability.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"3 <\/div>\n
\n

3 to 2-pin Adaptor and Polarity Protection<\/h1>\n
\n

The NF-A4x10 comes with an adaptor from 3-pin Molex to the 2-pin
\nconnectors used on many graphics cards or network and storage devices.
\nAn integrated diode provides polarity protection on 2-pin connections.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"OmniJoin <\/div>\n
\n

OmniJoin Adaptor Set<\/h1>\n
\n

Many devices featuring 40mm fans use proprietary fan headers, so the
\nNF-A4x10 comes with Noctua’s . Just cut the original fan’s cable, fix it
\n to the adaptor using the supplied 3M Scotchlok\u2122 connectors and you can
\nplug the NF-A4x10 to proprietary fan headers!\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"Extensive <\/div>\n
\n

Extensive cabling options<\/h1>\n
\n

The fan’s short 20cm primary cable minimises cable clutter in typical
\napplications while the supplied 30cm extension provides extended reach
\nwhen necessary. Both cables are fully sleeved.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/td>\n<\/tr>\n

\n
\n
\n
\n \"6-year <\/div>\n
\n

6-year manufacturer\u2019s warranty<\/h1>\n
\n

Noctua fans are renowned for their impeccable quality and outstanding
\nlongevity. Like all Noctua fans, the NF-A4x10 features an MTBF of more
\nthan 150.000 hours rating and comes with a full 6-year manufacturer\u2019s
