Noctua NF-A14 PWM 140x140x25

The NF-A14 is a high-quality 140mm square frame silent fan that meets Noctua's Advanced Acoustic Optimization AAO standard. Thanks to its square shape and 140mm mounting holes (124.5mm spacing) it is ideal for use with liquid cooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design features such as Flow Acceleration Channels, the NF-A14 increases the renowned silent dissipation performance of the award-winning NF-P14. 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 1500 to 1200 rpm during control. PWM. Its performance-oriented 1500 rpm maximum speed and full speed control options make the NF-A14 PWM an ideal choice for users who strive to find the perfect balance between excellent cooling capacity and quiet operation, whether in liquid cooling radiators, in heatsinks or in case ventilation.

The NF-P14 fan has become the go-to choice among PC enthusiasts looking for high-quality, silent 140mm fans. Thanks to its deep aerodynamic optimization, the NF-A14 provides higher static pressure and even better noise airflow ratio than its acclaimed predecessor.

The NF-A14 with 140mm square frame and 140mm mounting holes (124.5mm spacing) is a high-end replacement for 140mm case fans and are perfect for use with liquid cooling radiators 140 mm, since its square shape guarantees total coverage and the best pressure performance.

The NF-A14 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.

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.

The NF-A14 features Noctua's renowned second-generation SSO optimized bearings. With SSO2s, the rear magnet is located closer to the shaft to provide greater stability, precision and durability.
