Noctua NF A14x25r G2 PWM 140mm Fan

Noctua NF-A14x25r G2 PWM: Next-Gen 140mm Round-Frame Fan

The Noctua NF-A14x25r G2 PWM represents the pinnacle of 140mm fan engineering, combining a round-frame design with Noctua’s second-generation aerodynamic advancements. Delivering 140.2 m³/h airflow at just 22.6 dB(A), this PWM-controlled fan features the revolutionary AAO (Advanced Acoustic Optimization) 2.0 frame and Sterrox liquid-crystal polymer blades. Furthermore, its SSO3 bearing with magnetic stabilization ensures >300,000 hours MTBF for unparalleled reliability.

Next-Generation Performance:

Engineered with Flow Acceleration Channels 2.0 and turbulence-reducing notches, the NF-A14x25r G2 achieves 2.34 mm H₂O static pressure while maintaining whisper-quiet operation. The round-frame design improves compatibility with older case mounts, and the PWM control allows precise 300-1500 RPM speed adjustment. Moreover, the Sterrox LCP blades maintain dimensional stability under heat for consistent performance in high-temperature environments.
