Noctua 120mm Nf-a12x25 Uln 1200rpm Fan (NF-A12x25-ULN)

Manufacture # Noctua  | Model # A12x25-ULN

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. This 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.

Features:

• Providing 1200 and 900 rpm speed settings via the supplied adapter
• The ULN (Ultra-Low-Noise) version is tailor made for serious silent enthusiasts who demand super-slow running speeds
• Noctua’s 120mm fans such as the NF-A12x25-ULN and NF-S12A are renowned as being among
• Its further improved efficiency and novel, state-of-the-art engineering
• The NF-A12x25-ULN represents another step up in performance and manufacturing
• The sophisticated aerodynamic design allows for a pressure
• The true jack-of-all-trades with excellent performance in both static pressure demanding and airflow
• High-pitched noises when installed in typical applications such as on heatsinks or radiators
• It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (SPL) when working against back pressure
• The NF-A12x25-ULN impeller features suction side Flow Acceleration Channels
• This measure reduces suction side flow separation
• The has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm.
