The Ultimate Dual 140mm Fan Set for Premium Systems
Succeeding the legendary NF-A14, the Noctua NF-A14x25 G2 PWM Sx2-PP chromax.black dual fan set defines a new benchmark for uncompromising quiet cooling. This premium package bundles two state-of-the-art 140mm fans tailored specifically for high-end chassis layouts and extreme water cooling loops. Integrating Noctua’s elite thermal engineering with a sleek, stealthy, all-black aesthetic, the chromax.black edition provides breathtaking cooling proficiency without disrupting the visual harmony of dark-themed PC builds.
Acoustic Perfection with Sx2-PP Speed Offset Technology
When fans are mounted in a push-pull orientation or run side-by-side on massive 280mm and 420mm liquid cooling radiators, overlapping acoustics can create a distracting harmonic resonance or periodic humming. To entirely eliminate this issue, the Sx2-PP (Push-Pull) set features two specialized fans with a precise, pre-calibrated speed offset of approximately 25 RPM. By preventing the fans from operating at the exact same rotational frequency, annoying beat frequencies are eliminated, guaranteeing the silkiest acoustic profile possible even under heavy system loads.
State-of-the-Art Aerodynamics and Build Quality
At the core of each fan’s performance is a revolutionary Progressive Bend impeller featuring a Centrifugal Turbulator hub and flow-optimizing winglets. Forged from rigid Sterrox Liquid-Crystal Polymer (LCP), the fan blades maintain their shape under stress, allowing Noctua to achieve a record-breaking tip clearance of just 0.7mm. This extreme manufacturing tolerance dramatically minimizes leak flow, allowing the intelligent etaPERF motor and its SupraTorque technology to push vast amounts of air through restrictive cases and radiators without losing rotational speed. Driven by the time-tested SSO2 magnetic bearing, this set guarantees unparalleled durability and stabilization for years of uninterrupted operation.
