"The first-generation NF-A12x25 set a new benchmark for 120mm fans and has become one of the most successful Noctua fans of all time, so we’re excited to be able to offer another significant performance boost over this renowned model,” says Roland Mossig (Noctua CEO). “Using the same motor and aerodynamic design approach as the 14cm G2 model, the new NF-A12x25 G2 has been further refined in virtually all respects, which enables it to further push the envelope in terms of performance-to-noise efficiency.“

According to Noctua, the NF-A12x25 G2 brings a significant boost in performance-to-noise efficiency, making it suitable for almost every scenario, from water cooling radiators to heatsinks and case fan setups.

The new Noctua NF-A12x25 G2, just as the 140mm NF-A14x25 G2, is made from Sterrox LCP and features a tip-clearance of only 0.5mm, as well as uses a new optimized Progressive Bend impeller with winglets, Flow Acceleration Channels, and the new Centrifugal Turbulator Hub. According to Noctua, the AAO (Advanced Acoustic Optimisation) frame can be combined with the included NA-AVG1 anti-vibration gasket for radiators or the NA-IS1-12 inlet side spacer frame.

As said, the Noctua NF-A12x25 G2 uses an improved etaPERF motor with Smooth Commutation Drive 2 technology and SupraTorque feature, which gives it even better performance on heatsinks and radiators.

Like all previous Noctua fans, the NF-A12x25 G2 will also be available in a standard PWM version with 1800rpm maximum speed and an ultra-quiet LS-PWM version with up to 1100rpm. Noctua will also offer it in an Sx2-PP set that contains two fans that are offset in speed by +/- ~50rpm, which are meant for push-pull configurations.

The Noctua NF-A12x25 G2 is backed by a 6-year warranty, and has an MSRP of NF-A12x25 G2 PWM: €34.90 / $34.90, NF-A12x25 G2 PWM Sx2-PP: €64.90 / $64.90, NF-A12x25 G2 LS-PWM: €34.90 / $34.90.
