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
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.
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.
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.
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.
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.
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
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.
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
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
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
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.
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.
