Noctua NF-A12x25 5V 120mm Fan

The Noctua NF-A12x25 5V 120mm Fan is a dedicated 5V version of Noctua’s award-winning, premium-quality NF-A12x25 fan. It features an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures like Flow Acceleration Channels. This fan is renowned for its superior performance and outstanding quietness of operation, making it ideal for various 5V applications.

Next-Generation Performance and Optimized Acoustics:

Superior Airflow and Static Pressure:

The NF-A12x25 5V delivers a maximum rotational speed of 1900 RPM. This results in a robust airflow of 96.2 m³/h and a static pressure of 2.07 mm H₂O. Therefore, this fan excels in both static pressure demanding and airflow demanding applications, providing highly optimized performance.

Exceptional On-Application Acoustics:

While many fans produce unpleasant, high-pitched noises when installed in typical applications (e.g., on heatsinks or radiators), Noctua carefully fine-tuned the NF-A12x25 for optimal on-application acoustics. It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (SPL) of 21.4 dB(A) when working against back pressure. Flow Acceleration Channels further enhance efficiency and reduce vortex noise.

Durable Construction and Versatile Connectivity:

Sterrox® LCP Material and SSO2 Bearing:

The NF-A12x25’s impeller is crafted from Noctua’s novel Sterrox® liquid-crystal polymer (LCP) compound. This material features extreme tensile strength, an exceptionally low thermal expansion coefficient, and damping characteristics ideal for reducing resonance and vibration. The fan also utilizes an SSO2 bearing, ensuring superb running smoothness and excellent long-term stability. A metal-reinforced motor hub further guarantees ultimate precision and increased stability.

Flexible 5V Power and Adaptor Cables:

Being a 5V fan, the NF-A12x25 5V cannot run at 12V and will be damaged with typical 12V power sources. However, it offers full flexibility for various 5V applications. The fan includes a USB power adaptor cable, allowing it to run on power banks, devices with USB host ports, or USB power supplies (like smartphone chargers). Additionally, the OmniJoin adaptor set enables connection to proprietary fan headers, offering extensive compatibility for replacing existing 5V fans or for new custom applications.

Advanced Design and Long-Term Reliability:

AAO Frame with Microstructures:

Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads. They also incorporate Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures. These elements further refine the fan’s performance-to-noise efficiency. The ultra-tight tip clearance of only 0.5mm sets a new benchmark for 120mm fans, improving efficiency against back pressure.

Exceptional Longevity and Included Accessories:

Noctua fans are renowned for their impeccable quality and outstanding longevity. The NF-A12x25 5V boasts an MTTF (Mean Time To Failure) rating of more than 150,000 hours, ensuring a robust and dependable product. The fan comes with a 30cm extension cable, NA-AV2 anti-vibration mounts, a USB power adaptor cable, an OmniJoin adaptor set, and fan screws, providing a complete package for diverse applications.
