Noctua Housing fan nf-a6x25 pwm

• Rotation speed from 500 to 3000 rpm
• Integrated anti-vibration pads
• Maximum noise of 19.3 dB (A)
• SSO2 storage system
• Incl. Low-noise adapter and 30 cm extension cable

If you are looking for a high-quality and quiet premium-quality fan, you are in the right place with the Noctua NFA6x25: it draws on aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO frame system. The PWM version uses the Noctua-developed PWM control chip NE-FD1 for fully automatic speed control and comes with a low-noise adapter, which can reduce the maximum speed in PWM operation to 2300 rpm.

The impeller of the NF-A6x25 is equipped on the suction side with so-called flow acceleration channels. The acceleration of the airflow in the critical outer regions of the fan blades reduces suction vortex shedding, resulting in higher efficiency and lower turbulence noise.

Noctua's Advanced Acoustic Optimization (AAO) frames feature built-in vibration buffers, as well as a graded inlet area and an interior microstructure for even better performance / noise efficiency.

The NF-A6x25 is equipped with the second generation of Noctua's proven SSO storage system. With SSO2, the back magnet sits closer to the fan axis for even better stabilization, resulting in further improved precision and durability.
