Noctua NF-A12x25 G2 LS-PWM, Premium-Quality Quiet 120mm PC Fan (Brown)

The NF-A12x25 G2 is the second-generation, further improved successor to the groundbreaking NF-A12x25 and 120mm sister model to the award-winning 140mm
NF-A14x25 G2: Like its much-acclaimed predecessor, it is made from Sterrox LCP and features an extremely tight tip-clearance of only 0.5 mm. At the same time, its further optimised Progressive Bend impeller with winglets, Flow Acceleration Channels and the new Centrifugal Turbulator Hub enable the G2 version to surpass the original NF-A12x25s performance, making it Noctuas undisputed new flagship in the 120mm range. Just like its predecessor and the 140mm version, the NF-A12x25 G2 is a true all-rounder that yields superb results in all types of usage, regardless of whether its in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, static pressure demanding scenarios such as on heatsinks and water cooling radiators. For application-specific optimisation, the NF-A12x25 G2s AAO (Advanced Acoustic Optimisation) frame can be combined with the included NA-AVG1 anti-vibration gasket for a tighter seal on radiators or the optional NA-IS1-12 inlet side spacer frame, which can help to achieve superior suction acoustics and flow rates in challenging pull" configurations...
