State-of-the-art quiet cooling performance for CPU coolers in a sleek all-black design: The chromax.black version of the award-winning NF-A14x25r G2 round-frame 140-mm fan. Succeeding the iconic NF-A15, the NF-A14x25r G2 has quickly established itself as a new benchmark for premium quality quiet round-frame 140x25-mm 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 0.7 mm enables the G2 model to provide a significant boost in performance-to-noise efficiency over its renowned predecessor. Whether in low-impedance, high-airflow applications such as case cooling, or in high-impedance, high-pressure scenarios such as water cooling radiators, where its etaPERF motor with SupraTorque utilises additional torque reserves, the NF-A14x25r G2 is a proven winner. The chromax.black edition combines the NF-A14x25r G2's Sterrox liquid crystal polymer impeller, its extensive range of features and its groundbreaking quiet cooling performance with an attractive black design.
