Noctua NF-P12 Vortex Control 120mm 9 Blade Quiet PC Cooling Fan

Advanced Blade design with Vortex Notches Optimised for Sound, Low Noise as well as superior pressure and airflow performance.

The NF-P12 has been specifically developed for applications such as CPU coolers that demand superior pressure and airflow (CFM) performance. Thanks to
psychoacoustic optimizations like the
Vortex-Control Notches, the new SCD drive system and Noctua's premium-grade SSO-Bearing, the NF-P12 achieves
exceptional quietness and long-term stability.

We principally recommend the NF-P12 for the following applications:

  • CPU Cooling - CPU Coolers with tight fin-spacing
  • Water-cooling radiators with tight fin-spacing
  • Power supplies
  • Storage solutions
  • Computer Cases with very restrictive fan grills and filters
  • All applications with significant obstruction to airflow

Pressure-optimized Nine-Blade Design
Specifically developed for high-impedance applications such as CPU coolers, water-cooling radiators or cases with tight fan grills, the NF-P12 provides superior
pressure and airflow performance.

Vortex-Control Notches
Psychoacoustic optimizations like the staggered Vortex-Control Notches make the NF-P12 surprisingly quiet.

The pressure-optimized Nine Blade Design of the NF-P12 (P stands for pressure, power and performance) has been specifically developed for high-impedance
applications such as CPU coolers, water-cooling radiators, power supplies or cases with restrictive fan grills. It achieves outstanding static pressure and high
airflow at very low noise levels.

While most conventional 120mm rotors possess seven comparably narrow fan blades, the NF-P12's Nine-Blade Design uses nine large, closely spaced blades
with a relatively low angle of attack in order to achieve maximum static pressure and high airflow. As a result, the NF-P12 provides no less than 1.68 mm H2O at
1300 rpm, which is something that other fans merely achieve at 1600 rpm or more.

As a matter of principle, increasing the number of blades involves the risk of increasing the aerodynamic noise in general and noises caused by rotor-stator
interaction in particular. Basically, an increase in static pressure usually brings about higher noise emissions. In the case of the NF-P12, this problem is dealt with
by adding Vortex-Control Notches to the blades' trailing edges. Due to the two notches at the trailing edge, the flows along the suction and pressure side mix
more smoothly. This allows for less turbulence and velocity loss, which leads to a significant reduction in noise emission as well as increased efficiency. In order to
achieve the smoothest possible transition and maximum noise reduction, the Vortex-Control Notches are rounded in shape.

In addition to optimizing the joining of the flows at the trailing edge, the Vortex-Control Notches fulfil the task of psychoacoustic optimization: Due to the Vortex-
Control Notches, trailing edge vortices are split up into several smaller vortices. Thus the noise is spread over a wider range of frequencies and therefore
perceived as much less annoying.

The Vortex-Control Notches' effect of psychoacoustic optimization is further enhanced by the staggering of the notches. The Vortex-Control Notches are
staggered from blade to blade so that each blade creates a different vortex pattern. As a result, the fan's noise emission is better spread over the frequency
spectrum and thereby makes it yet more pleasant to the human ear.

Smooth Commutation Drive
The NF-P12's new drive system reduces torque variations and thereby ensures improved running smoothness.

Next to aerodynamic noise and bearing related noises, the so called "commutation noise" or "switching noise" can play a major role in the noise emission of axial
fans with brushless DC motors. At each transition from one stator coil to another, the rotor receives a sudden torque pulse when the next coil switches on. Each of
these torque pulses causes a minute deformation of the whole fan structure. Depending on rpm, torque and the material of the fan, this can result in noticeable
noises. Noctua's Smooth Commutation Drive system provides more continuous switching in order to achieve a smoother transition between the stator coils and
thereby significantly contributes to the fan's overall quietness.

Self-stabilizing oil-pressure bearing
Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.

Thanks to an optimised principle of operation, the self-stabilising oil-pressure bearing (SSO bearing) of the Noctua NF-S12 and NF-R8 series surpasses current
types of ball, sleeve or liquid bearings in terms of long-term stability and quietness.

The rotary motion of the axis generates pressure upon the special oil enclosed within the bearing. This causes the build-up of a dynamic pressure field that
centres and stabilises the axis within the bearing shell. While conventional liquid bearings employ the principle of hydrodynamic pressure too, the SSO bearing is
equipped with an additional magnet that supports the self-stabilisation of the rotor axis. This allows for a faster, more precise and more reliable centring of the
rotor axis and thus increases the long-term stability and quietness of the bearing: When the fan starts, the dynamic pressure field of the liquid bearing needs to
build up first, which results in an initial precession of the axis, the so called gyro effect. This amounts to an increased abrasion until the axis is stabilised through
the build-up of the dynamic pressure field, which may by and by lead to increased noise emission and bearing defects. Because of this, the SSO bearing
possesses a built in magnet, whose field ensures the immediate self-stabilisation of the rotor and hence reduces the gyro effect. In addition to the stabilisation
during the start-up phase of the fan, the supporting magnet allows for a more exact centring of the axis within the bearing shell and thus further reduces bearing
resistance, abrasion and noise emission.

The sleeve and ball bearings currently predominating the fan market exhibit major drawbacks: While conventional sleeve bearings initially have very low noise
emissions, they mostly possess unsatisfying long-term stability, which leads to a short overall lifespan and increasing noise after longer operating times. High
grade ball bearings, on the other hand, while providing satisfying long-term stability operate at slightly higher noise levels from the beginning. The SSO bearing
not only surpasses the quietness of conventional sleeve bearings but also the long-term stability of current top-of-the-line ball bearings.
