By 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.
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.
Focused 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. This allows the NF-F12 to rival the performance of conventional fans running at much faster speeds.
Varying 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 noise emissions over a broader frequency spectrum and thus make the fan's sound pattern more agreeable to the human ear.
Heptaperf 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.
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.
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. This results in reduced blade passing noise and improved airflow and pressure efficiency.
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-F12 is the first fan to feature the further optimised second generation of Noctua's famous time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis of rotation to provide even better stabilisation, precision and durability.
Metal 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.
Custom 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.
Ultra-Low Power Consumption
The NF-F12 draws only 0.6W, which is less than half many other fans in the same speed range. This not only makes 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.
Low-Noise Adaptor
The NF-F12 is supplied with a Low-Noise Adaptor (L.N.A.) which 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.
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 you to connect a second NF-F12 fan to the same PWM fan header for automatic control.
6 year manufacturer 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 six years manufacturer warranty.
