5V Version with PWM

5V fans are used in a wide range of devices and applications. The NF-A12x25 5V PWM is a proven premium solution that comes with a USB power adapter cable and an OmniJoin adapter set, providing you with full flexibility for both replacing existing 5V fans and in new, alternative applications.

Flow Acceleration Channels

The impeller of the NF-A12x25 is equipped on the intake side with so-called Flow Acceleration Channels. By accelerating the airflow in the critical outer regions of the fan blades, intake-side vortex detachment is reduced, resulting in higher efficiency and lower turbulence-related noise emissions.

AAO Frame System

Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated vibration dampers, a stepped inlet design, and inner surface microstructures.
