Produktinformation
Round 140mm frame with 150mm width
The NFA15 is tailormade for use on today's highend CPU coolers: While its 150mm width matches those of most highend heatsinks its 140mm height doesn't make it extend on top and thus ensures best case compatibility. The NFA15's standard 120mm mounting holes 105mm spacing also make it an ideal performance upgrade for 120mm case or CPU fans.

Flow Acceleration Channels
The NFA15 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.

AAO Frame
Noctua's AAO Advanced Acoustic Optimisation frames feature integrated antivibration 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.

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 which results in reduced blade passing noise and improved airflow and pressure efficiency.

SSO2 Bearing
The NFA15 features the further optimised second generation of Noctua's renowned timetested SSO bearing. With SSO2 the rear magnet is placed closer to the axis to provide even better stabilisation precision and durability.

Integrated AntiVibration Pads
Integrated AntiVibration Pads made from extrasoft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control the NFA15 PWM uses Noctua's novel custom designed NEFD1 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 low speeds.

LowNoise Adaptor
The NFA15 PWM is supplied with a LowNoise Adaptor L.N.A. that reduces the maximum fan speed from 1200 to 900rpm. The L.N.A can be used either to run the fan at a fixed speed of 900rpm 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 the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply.

6 years manufacturer's warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans the NFA15 features an MTBF of more than 150.000 hours rating and comes with a full 6 years manufacturer's warranty
