Noctua NF-A6x25 5V PWM 60mm Fan

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A6x25 5V PWM is a dedicated 5V version of Noctua’s highly optimized, premium-quality quiet 60x25mm fan. Smooth Commutation Drive technology and Noctua’s reference-class SSO2 bearing guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin™ Adaptor Set and a 6-year manufacturer’s warranty, the NF-A6x25 5V PWM is a premium choice for demanding 5V applications that require PWM control..

Noctua NF-A6x25 5V PWM Features

Image shows 5V version logo.

5V version
Many devices, such as network or storage solutions, use 5 volt 60mm fans. With the same operating voltage and the included OmniJoin™ adaptor set that makes it compatible with proprietary fan headers, the NF-A6x25 5V is ideal for replacing noisy or broken 5V 60mm fans

Image shows Polarity protection logo.

Polarity protection
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 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.

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 Optimization) 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.

Image shows Stepped Inlet Design logo.

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 plowing 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 Smooth Commutation Drive 2 logo.

Smooth Commutation Drive 2
The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A6x25 remarkably quiet even at very close distances.

Image shows OmniJoin™ Adaptor Set logo.

OmniJoin™ Adaptor Set
Many devices featuring 60mm fans use proprietary fan headers, so the NF-A6x25 5V comes with Noctua’s OmniJoin Adaptor Set. Just cut the original fan’s cable, fix it to the adaptor using the supplied 3M Scotchlok™ connectors and you can plug the NF-A6x25 5V to proprietary fan headers!

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.

Notes and Warnings

Being a 5V fan, the NF-A6x25 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers
