Quiet box fan 60x25mm
Overview
Exceptionally quiet!
With an advanced aerodynamic design, the NF-A6x25 is a highly optimised, high-end silent fan in 60x25mm format, featuring Flow Acceleration Channels and the Noctua AAO frame.
The PWM version is equipped with the exclusive Noctua NE-FD1 IC, which allows full automatic speed control via the 4-pin fan connectors, and a low-noise adapter is provided to cap the maximum speed (from 3000 to 2300 rpm) during PWM phases. This quiet, unobtrusive fan with SSO2 bearing and Noctua's renowned manufacturing quality makes it the solution of choice for the most demanding users.

Smaller hub size
Thanks to a more streamlined and compact motor design, the hub is smaller in size compared to traditional 6cm fans. By increasing the blade area, the NF-A6x25 significantly improves the pressure level as well as the flow.
|
 |
Flow Channels The impeller of the NF-A6x25 is equipped with flow ducts on the face of the fan. The flow acceleration generated at the tips of the blades creates a more massive, less dispersed suction, thus increasing efficiency and reducing vortex-related noise disturbance.
|
 |
AAO Frame
Noctua's AAO(Advanced Acoustic Optimisation) frames are equipped with anti-vibration mounts and benefit from exclusive optimisations to push the limits of performance and silence.
|
 |
Stepped Inlet Design
Noctua's Stepped Inlet design adds turbulence to the inlet flow, allowing a gradual transition from laminar to turbulent flow. This reduces noise emissions, generates a more massive flow and increases suction power.
|
 |
Inner Surface Microstructures
As the blade tips move in a boundary layer influenced by the presence of an Inner Surface Microstructure, the flow separation that takes place at the suction level becomes almost non-existent.
|
 |
Integrated anti-vibration dampers
The integrated anti-vibration mounts, made of extra soft silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard fastening systems.
|
 |
SSO2 Bearing
This is the latest generation of the SSO2 bearing, which is even more optimised. The SSO2 is equipped with a rear magnet closer to the axis for better precision, durability and stability.

Exclusive PWM IC system with SCD
Compatible with PWM automated speed control systems, the NF-A6x25 PWMs feature the latest NE-FD1 PWM IC that incorporates Smooth Commutation Drive (SCD) technology. By generating less abrupt torque pulses, SCD eliminates the noise associated with PWM switching for quieter fan operation at lower speeds.
|
 |
3-speed control for total flexibility
With access to 3000, 2400 and 1600 rpm speed settings via the supplied adapters(low noise and ultra low noise), the NF-A6x25 FLX(FLX for Flexibility) offers great flexibility in terms of flow and silence settings.
|
 |
Multiple wiring options
While the main fan power cable is short(20cm), a 30cm cable is provided to solve any distance problems. Both cables are fully sheathed.
|
 |
6-year manufacturer's warranty
Noctua fans have a proven track record for both quality and durability. As with all Noctua models, the NF-A6x25 has an MTBF of more than 150,000 hours of testing and comes with a full 6-year manufacturer's warranty.

Perfect
Nothing to complain about (except maybe the colour, but you know what it's like when you buy a Noctua)
Not a single noise, a formidable efficiency despite the small size of the fan.
The bundle is very complete (especially the little anti-vibration rubber)

Very good
Very good fan, very quiet, don't even need the connection to reduce the speed, it is very quiet. But lacks a little breath I find for a fan that goes out 3000rpm. Otherwise very good overall.
