Noctua NF-A14x25r G2 PWM Sx2 PP chromax.black 140mm Next Gen Fan Set NF-A14X25R-G2-PWM-SX2-PP-CH-BK

[features] Succeeding the iconic NF-A15; the NF-A14x25r G2 has quickly established itself as a new benchmark for premium quality quiet round-frame 140x25mm 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 0.7mm enables the G2 model to provide a significant boost in performance-to-noise efficiency over its renowned predecessor. At the same time; its etaPERF motor with SupraTorque can leverage extra torque headroom when required; which makes the NF-A14x25r G2 an ideal upgrade for NH-D15; NH-D15S and NH-U14S heatsinks. The Sx2-PP set contains two fans that are slightly offset in speed (+/-
25rpm) 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 equipping coolers with two fans in a push-pull configuration. Topped off with Noctua’s trusted premium-grade SSO2 bearing; more than 150;000 hours MTTF and a 6-year manufacturer’s warranty; the NF-A14x25r G2 PWM Sx2-PP chromax.black is the perfect choice for users who are looking for a dual 140mm round fan set that combines cutting-edge quality; quietness and performance in an all-black style.
Award-winning NF-A14x25r G2 design Providing a significant performance boost over the renowned NF-A15; the NF-A14x25r G2 has become a new favourite among quiet cooling enthusiasts. With rave reviews and dozens of awards from hardware media around the world; the G2 model is a proven premium choice for the highest demands. chromax.black edition From the impeller and fan frame to the anti-vibration pads; anti-vibration mounts; screws and cables; the chromax.black edition is black from head to toe; making it easy to integrate into all-black PC builds and various other environments. Push-pull set Bundling two NF-A14x25r G2 PWM fans that are speed-offset by +/- 25rpm in order to avoid undesired acoustic interaction phenomena; the Sx2-PP set is the ideal choice for push-pull configurations on 140mm class coolers such as the NH-D15; NH-D15S or NH-U14S. Highly optimised P/Q curve for all applications The NF-A14x25 G2’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-A14x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure and airflow demanding applications.
