Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and an AAO frame, the NF-A6x25 5V PWM is a PWM-enabled 5V variant of Noctua’shighly optimised, premium-quality quiet 60x25mm fan. The custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive technology and Noctua’sreference-class SSO2 bearing guarantee superb running smoothness and excellentlong-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.
5V PWM version

5V PWM version

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

Polarity protection

As many devices using 5V fans feature proprietary connectors and documentation of the pin alignment may not be available, the fanfeatures an integrated diode for polarity protection. This way, you're on the safe side if you accidentally connect it with reverse polarity.
Reduced Motor Hub Size

Reduced Motor Hub Size

Thanks to its streamlined, compact motor design, the NF-A6x25's motor hub is smaller than with conventional 6cm fans. Thisallows for more blade surface area and thus contributes to the NF-A6x25's superior airflow and pressure performance.
Flow Acceleration Channels

Flow Acceleration Channels

The NF-A6x25 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer bladeregions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
AAO Frame

AAO Frame

Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary SteppedInlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
Inner Surface Microstructures

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flowseparation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressureefficiency.
Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations whilemaintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
Custom-designed PWM IC with SCD

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the fan uses Noctua's custom-designed NE-FD1 PWM IC that integratesSmooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lowspeeds.
SSO2 Bearing

SSO2 Bearing

The NF-A6x25 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnetis placed closer to the axis to provide even better stabilisation, precision and durability.
Extensive cabling options

Extensive cabling options

The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extensionprovides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second fan to the same PWM fan header forautomatic control.
OmniJoin™ Adaptor Set

OmniJoin™ Adaptor Set

Many devices featuring 60mm fans use proprietary fan headers, so the NF-A6x25 5V PWM 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 PWM to proprietary fanheaders!
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A6x25features an MTBF of more than 150.000 hours rating and comes with a full 6-year manufacturer's warranty.
