State-of-the-art quiet cooling performance for PC cases and water cooling radiators in a sleek all-black design: The chromax.black dual set 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 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. The Sx2-PP set contains two fans that are slightly offset in speed (+/- ~50rpm) in order to avoid undesirable harmonic phenomena such as beat frequencies, which can be heard as intermittent vibrations or periodic humming due to interference. This makes it ideal for both push-pull applications and situations where two or more fans are running side by side such as in typical case fan configurations as well as on 240 or 360mm water cooling radiators. 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 Sx2-PP chromax.black is the perfect choice for users who are looking for a dual 120mm fan set that combines cutting-edge quality, quietness and performance in an all-black style.
