Noctua NF-A12x25 G2 PWM chromax.black PremiumQuality Quiet 120mm PC Fan Black
NF-A12x25 G2 PWM chromax.black
Next-gen black 120mm fan
State-of-the-art quiet cooling performance for PC cases and water cooling radiators in a sleek all-black design: The chromax.black version of the award-winning NF-A12x25 G2 120mm fan.
Succeeding the iconic NF-A12x25, the NF-A12x25 G2 has quickly established itself as a new benchmark for premium quality quiet 120x25mm fans. Its advanced aerodynamic engineering featuring a novel Progressive Bend impeller design with a Centrifugal Turbulator hub, winglets, and a record tight tip clearance of only 0.5mm enables the G2 model to provide a significant boost in performance-to-noise efficiency over its renowned predecessor: Whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on water cooling radiators, where its etaPERF™ motor with SupraTorque™ allows leveraging extra torque headroom, the NF-A12x25 G2 is a proven winner.
The chromax.black edition combines the NF-A12x25 G2’s Sterrox® liquid-crystal polymer impeller, comprehensive feature set and breakthrough quiet cooling proficiency with an attractive black design, which can be customised with coloured anti-vibration pads that are available separately.
Topped off with Noctua’s trusted premium-grade SSO2 bearing, an MTTF rating of more than 150,000 hours and a 6-year manufacturer’s warranty, the NF-A12x25 G2 PWM chromax.black is the perfect choice for users who are looking for cutting-edge quality, quietness and performance in an all-black style.
