Noctua NF-A8 PWM 80x80x25

The NF-A8 is a highly optimized and high quality 80mm silent fan. Featuring Noctua's AAO (Advanced Acoustic Optimization) framework and sophisticated aerodynamic design features such as Flow Acceleration Channels, the NF-A8 improves on the NF-A8's renowned silent cooling performance. R8, how award-winning it has been. The PWM version uses Noctua's specially designed NE-FD1 IC for fully automatic speed control via 4-pin fan connectors and is provided with a Noise Reduction Adapter that reduces the maximum speed from 2200 to 1750 rpm during operation. PWM control. Its smooth and silent operation, its renowned SSO2 bearings and Noctua's high quality make it the best option for the highest demands.

Noctua's NF-R8 fan has become the go-to choice among PC enthusiasts looking for high-quality, silent 80mm fans. Thanks to its deep aerodynamic optimization, the NF-A8 provides higher static pressure and better airflow/noise ratio than its acclaimed predecessor.

The NF-A8 rotor has Flow Acceleration Channels on the suction side. By increasing the airflow velocity in the crucial outer regions of the blades, this measure reduces flow separation on the suction side and thus resulting in higher efficiency and lower vortex noise.

Noctua's AAO (Advanced Acoustic Optimization) frames feature built-in anti-vibration pads, as well as step-in input design and internal surface microstructures (both proprietary to Noctua), which further refine sonic efficiency and performance. fan performance.

Noctua's step-through inlet design adds turbulence to the air inlet to facilitate the transition from laminar flow to turbulent flow, reducing inlet pitch noise, improving flow adhesion, and increasing suction capacity, especially in environments with restricted space.

With the ends of the fan blades colliding with the boundary layer created by the Inner Surface Microstructures, the flow separation from the suction side of the blades decreases significantly, resulting in noise. smaller pitch between the blades, better air flow and greater pressure efficiency.

Integrated anti-vibration pads made of extra-soft silicone minimize the transmission of vibrations per minute while maintaining compatibility with all standard mounting systems and fan clips used on coolers.
