The NF-A12X25 5V is a quiet 120 mm premium fan with square AAO (Advanced Acoustic Optimization) frame. Due to the 5V specification, it is not suitable for operation on motherboard headers . The fan runs pleasantly quiet with a maximum of 21.4 dB (A) and still offers an air throughput of up to 56.6 cfm and a static pressure of 2.07 mm H2O.

- 5V version incl. USB and OmniJoin adapter cable for maximum compatibility
- Flow Acceleration Channels for a smoother running sound
- 1,900 revolutions per minute at 56.6 cfm & 21.4 dB (A)
- Convincing quality with 6 years manufacturer's warranty
The Noctua NF-A12X25 5V in detail
The 5V fan can be powered by the USB adapter on USB power supplies and power banks for smartphones. With the OmniJoin adapter set and the integrated reverse polarity protection it is also possible to safely install the fan in many devices with proprietary fan connections such as 3D printers, digital video recorders or network and storage solutions.
The impeller of the NF-A12X25 5V is equipped on the suction side with so-called flow acceleration channels . Acceleration of the airflow in the critical outer regions of the fan blades reduces suction vortex shedding, resulting in higher efficiency and lower turbulence-related noise emissions.
NoctuaAdvance Acoustic Optimization (AAO) frames incorporate built-in vibration buffers, as well as a stepped inlet area (stepped inlet design) and an interior microstructure (inner surface microstructures) for even better performance / noise efficiency.
Made of extra-soft silicone anti-vibration pads reduce the transmission of minimal vibration and are at the same time compatible with all standard screws and commercially available mounting systems or fan brackets used in CPU coolers.
To ensure the highest level of manufacturing precision , minimum tolerances and excellent long-term stability, the NF-A12X25 uses 5Von a CNC milled bearing shell made of brass back. The fan is equipped with the further optimized 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.
Noctua's fans are known for their flawless quality and outstanding longevity. Like all Noctua fans, the NF-A12X25 5V has an MTBF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
