Noctua NF-A14x25 G2 PWM Next-gen 140mm Fan

Building on the legacy of the award-winning NF-A14 and the breakthrough engineering of the NF-A12x25, the Noctua NF-A14x25 G2 represents the brand’s next-generation 140mm flagship fan. Constructed from advanced Sterrox® LCP material, it features a highly refined Progressive-Bend impeller with winglets, Flow Acceleration Channels, and a Centrifugal Turbulator hub design. Combined with an ultra-tight 0.7mm tip clearance, these innovations enable the NF-A14x25 G2 to deliver even higher cooling efficiency and quieter acoustic performance than its acclaimed predecessor.
