Noctua NF-A12x25 12V Fan, PWM

Noctua NF-A12x5

The NF-A12x25 is a next-generation, highly optimised 120mm fan that integrates Noctua's latest aerodynamic innovations to achieve unprecedented low-noise cooling performance. It uses state-of-the-art technologies such as the AAO frame (Advanced Acoustic Optimization) or the Flow Acceleration Channels and combines them with a record-tight tip spacing of only 0.5 mm, which is made possible by the use of the new Sterrox Liquid System. Crystal polymer (LCP) and a metal-reinforced motor hub and axle for maximum precision. Following the Noctua A-series approach, the NF-A12x25 is a true all-rounder that delivers excellent results in all applications, regardless of whether it is low-resistance, airflow-oriented applications such as case cooling or high-performance cooling. Impedance, pressure-intensive scenarios such as with heat sinks and water coolers.

FLX

The 3-pin FLX version offers a speed setting of 2000/1700/1350 rpm via the included low-noise adapter to ensure full flexibility in the configuration of the fan for maximum cooling performance or almost noiseless acoustics. The NF-A12x25 is characterised by exceptional smoothness and is a product of the highest quality. The superior efficiency, the innovative construction and the pioneering materials make it a first-class choice for the most demanding requirements.

Specifications:

PWM

The 4-pin PWM version supports fully automatic speed control via PWM fan headers and is supplied with a low-noise adapter to reduce the maximum speed from 2000 to 1700 rpm. The NF-A12x25 is characterised by exceptional smoothness, the SSO2 reference bearing from Noctua and a comprehensive range of accessories is through and through a product of the highest quality. The superior efficiency, the innovative construction and the pioneering materials make it a first-class choice for the most demanding requirements.

Specifications:

LS-PWM

Thanks to the PWM support and low speed, this 4-pin version is suitable for semi-passive systems and silent applications.

ULN

The ULN version of the fan offers super-low speed options (1200/900 rpm) you can choose from enabling nearly silent operation. Ideal for ultra-low noise applications and users who are particularly sensitive to noise.
