Спецификации на Noctua NF-A12X25 ULN High-efficiency quiet 120mm fan socket: n/a 120 mm (вентилатори вентилатори)

Noctua 120*120*25 NF-A12X25 ULN High-efficiency quiet 120mm fan, 9010018100372

Pioneering design

With Sterrox® LCP & record tight 0.5mm tip clearance

Highly optimised P/Q curve

For outstanding performance in all applications

3-pin ULN version

Provides 1200/900rpm speed settings via Low-Noise Adaptors

The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance.

It takes state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame or Flow Acceleration Channels and combines them with a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox® liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision.

Following the approach of Noctua’s A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators.

The 3-pin ULN version provides super-slow 1200/900rpm speed settings for ultra-low-noise applications and highly noise-sensitive users who demand near-silent acoustics.

Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the NF-A12x25 is a premium-quality product through and through.

Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.

Key features

Sterrox® liquid-crystal polymer compound

The NF-A12x25’s impeller is made from Noctua’s novel Sterrox® liquid-crystal polymer (LCP) compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics that are ideal for reducing resonance and vibration phenomena in advanced fan-blade designs.

Ultra-tight tip clearance

The NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.

Metal-reinforced motor hub

The centrepiece of the NF-A12x25’s motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination, both measures ensure ultimate precision and increased stability in the critical hub area.

Highly optimised P/Q curve

The NF-A12x25’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.
