Press Release

Vienna, November 9th 2011 - Noctua today introduced the new NF-F12 120mm Focused Flow™ fan. Teaming up eleven stator guide vanes with a specially conceived seven blade impeller, the NF-F12’s Focused Flow™ system creates outstanding static pressure and focuses the airflow for superior performance on heatsinks and radiators. At the same time, a wide range of advanced aerodynamic design measures, second generation SSO-Bearings and Noctua’s new, custom designed PWM IC for fully automatic control guarantee astounding quietness of operation.

Our award-winning NF-P12 has become a standard choice for pressure demanding applications such as CPU coolers and radiators, but we’ve been striving to achieve even better performance in this domain, and this is how the NF-F12 was born,
explains Mag. Roland Mossig, Noctua CEO.
Due to the stator guide vanes focussing the airflow, it can push the air through dense fin stacks more effectively. This type of design has mostly been used for noisy high speed fans so far, so our engineers have put a lot of thought into keeping the noise in check.


The NF-F12 uses a wide range of aerodynamic optimisations in order to refine the fan’s acoustic qualities. For example, the NF-F12’s stator guide vanes are set out in Varying Angular Distance and feature Vortex-Control Notches. Both measures help to spread the noise emission over a broader frequency spectrum and thus make the fan’s sound pattern more agreeable to the human ear. Another novel measure introduced with the NF-F12 is the Stepped Inlet Design, which adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow. This measure reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments.

In addition to its advanced aerodynamic features, the NF-F12 is the first fan to implement the further optimised second generation of Noctua’s renowned, time-tested SSO bearing as well as the novel, custom designed NE-FD1 PWM IC for fully automatic PWM speed control. The NE-FD1 integrates Noctua’s Smooth Commutation Drive (SCD) technology for quieter operation and allows for ultra-low power consumption: Drawing only 0.6W, the NF-F12 consumes more than 50% less than many fans in the same speed range. This doesn’t only make it eco-friendly but also cuts down the electricity bill.

Last but not least, the NF-F12 comes with modular cabling, integrated anti-vibration pads and two speed settings for full flexibility. Its commanding performance, exhaustive set of features and Noctua’s trusted premium quality make it an elite choice for use on air coolers, radiators and other pressure demanding applications.

Price and availability
The NF-F12 will be available immediately at a recommended retail price of EUR 19.90 / USD 24.90.

Details

http://www.noctua.at/images/feature_logos/focused_flow.pngFocused Flow™ Frame
Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flow™ frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-F12 to rival the performance of conventional fans running at much faster speeds.


http://www.noctua.at/images/feature_logos/vad.pngVarying Angular Distance and Vortex Control Notches
The NF-F12’s stator guide vanes are set out in Varying Angular Distance and feature Vortex-Control Notches. Both measures help to spread the noise emission over a broader frequency spectrum and thus make the fan’s sound pattern more agreeable to the human ear.


http://www.noctua.at/images/feature_logos/heptaperf.pngHeptaperf™ Impeller
Custom designed for the new Focused Flow™ frame and to work in tandem with the eleven stator guide vanes, the NF-F12’s seven blade Heptaperf™ impeller has been carefully optimised to achieve a perfect balance between power and quietness.


http://www.noctua.at/images/feature_logos/sid.pngStepped 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.


http://www.noctua.at/images/feature_logos/ism.pngInner 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.


http://www.noctua.at/images/feature_logos/antivib_f12.pngIntegrated 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.


http://www.noctua.at/images/feature_logos/sso2.pngSSO2 Bearing
The NF-F12 is the first fan to feature 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.


http://www.noctua.at/images/feature_logos/metal_shell_f12.pngMetal bearing shell
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-F12 sports a CNC milled bearing shell made entirely from brass.


http://www.noctua.at/images/feature_logos/metal_shell_f12.pngCustom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-F12 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.


http://www.noctua.at/images/feature_logos/power_consumption.pngUltra-Low Power Consumption
The NF-F12 draws only 0.6W, which is more than 50% less than many fans in the same speed range. This doesn’t only make it eco-friendly but also cuts down the electricity bill: Compared to a typical 2W fan, this allows you to save about half the price of the NF-F12 after 5 years of continuous use.


http://www.noctua.at/images/feature_logos/lna_f12.pngLow-Noise Adaptor
The NF-F12 is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1500 to 1200rpm. 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.


http://www.noctua.at/images/feature_logos/cabling_f12.pngExtensive 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-F12 fan to the same PWM fan header for automatic control.


http://www.noctua.at/images/feature_logos/warranty.png6 years manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-F12 features an MTBF rating of more than 150.000 hours and comes with a full 6 years manufacturer’s warranty.
