Noctua NF-A6x25 5V PWM, Premium Quiet Fan, 4-Pin, 5V Version (60mm, Brown)

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, PWM support and the included OmniJoin adaptor set that makes it compatible with proprietary fan headers, the NF-A6x25 5V PWM is ideal for replacing noisy or broken 5V 60mm fans with PWM.
Please Note: 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.



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.



SSO2 bearing

The NF-A6x25 features the further optimised 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 stabilisation, precision and durability.



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.
