Description 

Noctua NF-A6x25 PWM 60mm Fan

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO frame, the NF-A6x25 PWM is a highly optimized, premium quality quiet fan in 60x25mm size. The PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed controlvia 4-pin fan headers and comes with a Low-Noise Adapter to reduce maximum speed during PWM control from 3000 to 2300rpm.  It's superb running smoothness, SSO2 bearing and Noctua's trusted premium quality make it an elite choice for the highest demand.

 

Noctua NF-A6x25 PWM Features

Noctua NF-A6x25 PWM
Image shows Flow Acceleration Channels logo. Flow Acceleration Channels
The NF-A6x25 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.
Image shows  Reduced Motor Hub Size logo. Reduced Motor Hub Size
Thanks to its streamlined, compact motor design, the NF-A6x25's motor hub is smaller than with conventional 6cm fans. This allows for more blade surface area and thus contributes to the NF-A6x25's superior airflow and pressure performance.
Image shows AAO Frame logo
. AAO Frame
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration 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.

Image shows Inner Surface Microstructures logo.

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.

Image shows Integrated Anti-Vibration Pads logo.

Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.

Image shows SSO2 Bearing logo.

SSO2 Bearing
The NF-A6x25 features the further optimized 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 stabilization, precision and durability.

Image shows Low-Noise Adapter logo.

Low-Noise Adapptor
The NF-A6x25 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 3000 to 2300rpm.  The L.N.A. can be used to either run the fan at a fixed speed of 2300rpm or to cap the maximum speed when using automatic PWM control.

Image shows Extensive Cabling Options logo.

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 a 4-pin y-cable allows the connection of a second NF-A6x25PWM fan to the same PWM fan header for automatic control.

Image shows 6 years manufacturer’s warranty logo.

6 years Manufacturer's Warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A6x25 features an MTBF of more than 150.000 hours rating and comes with a full 6 years manufacturer's warranty.
