Specification Brand : Noctua BulletPoint1 : Next-generation round-frame 140x25mm design for unprecedented quiet cooling performance on 14cm CPU coolers such as the NH-D15, NH-D15S or NH-U14S series BulletPoint2 : State-of-the-art engineering (Progressive-Bend impeller with winglets and Centrifugal Turbulator, Flow Acceleration Channels, AAO frame) and construction (Sterrox LCP, ultra-tight tip clearance) BulletPoint3 : 4-pin PWM version for automatic speed control via 4-pin PWM motherboard fan headers, 300-1500rpm speed range (near-silent at idle, powerful under load), fan stops at 0% PWM (semi-passive option) BulletPoint4 : Includes anti-vibration mounts, fan screws, Low-Noise Adaptor (LNA), extension cable and y-cable for running two PWM fans on the same header BulletPoint5 : Trusted Noctua quality with premium-grade SSO2 bearing (MTTF > 150,000 h), safety certifications from UL and TÜV, protected against reverse polarity, over voltage and over current (short-circuits) Color : TL-B14 CompatibleDevices : Desktop CoolingMethod : Air ExternallyAssignedProductIdentifier1 : 9010018100648 ExternallyAssignedProductIdentifier2 : 09010018100648 IncludedComponents : case fan ItemName : Noctua NF-A14x25r G2 PWM, Premium-Quality Quiet Round-Frame 140mm PC Fan, 4-pin (Brown) ItemPackageDimensions_Height : 20.3 centimeters ItemPackageDimensions_Length : 3.6 centimeters ItemPackageDimensions_Width : 15.3 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : desktop-computer-fans Manufacturer : Noctua Material : Sterrox LCP MaximumRotationalSpeed : 1500 rpm ModelNumber : NF-A14x25r G2 PWM NoiseLevel : 24.8 decibels NumberOfBoxes : 1 NumberOfItems : 1 PartNumber : NF-A14x25r G2 PWM PowerConnectorType : 4-Pin ProductDescription : Succeeding the award-winning NF-A15 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A14x25r G2 is Noctua’s next-generation round-frame 140mm flagship model: Made from Sterrox LCP, its highly optimised Progressive-Bend impeller with winglets, Flow Acceleration Channels and Centrifugal Turbulator Hub combined with a tip-clearance of only 0.7mm allow the NF-A14x25r G2 to further improve its predecessor’s renowned quiet cooling performance. This makes it not only a perfect fit for Noctua’s next-generation 140mm class heatsinks but also an excellent upgrade for existing cooler models such as the NH-D15(S) or NH-U14S series (Sx2-PP set recommended for push/pull configurations). The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 1500 to 1250rpm. Its ultra low-loss etaPERF motor with Smooth Commutation Drive 2 technology doesn’t only provide unprecedented energy efficiency and running smoothness but thanks to the new SupraTorque feature, it can also leverage extra torque headroom to keep the fan at its desired speed when working against back pressure, thereby ensuring even better performance on heatsinks. Topped off with Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the NF-A14x25 G2 is a premium-quality product through and through. Its superior performance, comprehensive feature set, cutting-edge construction and state-of-the-art materials set a new standard within Noctua’s portfolio and make it an elite choice for the most discerning demands.
