The NF-A14 is a quiet 140mm premium fan with a square AAO (Advanced Acoustic Optimization) frame. Its square shape and 140mm mounting holes (124.5mm hole spacing) make it an excellent choice for use on water cooling radiators or as housing fans. Thanks to advanced aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 achieves a further improvement in silent cooling performance compared to the award-winning NF-P14. The PWM version is equipped with Noctua's specially designed NE-FD1 IC for fully automatic speed control and is supplied with a low-noise adapter, which allows a reduction of the maximum speed from 1500 to 1200rpm. Its performance-oriented maximum speed and comprehensive speed control options make the NF-A14 PWM a top-of-the-line solution for users who want to achieve a perfect balance between excellent cooling performance and super smooth running - no matter whether on water cooling radiators, heat sinks or for housing ventilation!
Square 140mm frame
With its square frame and 140mm mounting holes (124,5mm hole spacing), the NF-A14 is an ideal premium upgrade for standard 140mm chassis fans. At the same time, it is perfectly suited for use on 140mm water cooling radiators, where the square shape guarantees a complete cover of the cooling fins and thus the best pressure performance.
Flow Acceleration Channels
The impeller of the NF-A14 is equipped with so-called flow acceleration channels at the suction side. The acceleration of the air flow in the critical outer regions of the fan blades reduces the suction-side vortex-ablation, resulting in higher efficiency and lower turbulence-related noise emission.
Integrated Anti-Vibration Pads
The anti-vibration pads, made from extra-soft silicone, reduce the transmission of minimal vibrations while being compatible with all standard mounting systems and fan clips used in CPU coolers.
SSO2 bearings
The NF-A14 is equipped with the further optimized second generation of Noctua's proven SSO storage system. At SSO2, the rear magnet sits closer to the fan axis, resulting in even better stabilization, resulting in further improved precision and durability.
Metal Bearing Shell
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerances and excellent long-term stability, the NF-A14 uses a CNC machined bearing shell made of brass.
PWM IC WITH SCD
The NF-A14 PWM supports fully automatic speed control via PWM and uses Noctua's new, specially designed NE-FD1 chip. This new PWM IC integrates Noctua's smooth commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan even quieter at low speeds.
Low-Noise Adapter
The NF-A14 PWM is supplied with a (L.N.A.) that reduces the maximum speed from 1500 to 1200rpm. This allows you to operate the fan at a constant 1200rpm or...
