Noctua NF A12x25 LS PWM 120mm Fan

Noctua NF-A12x25 LS-PWM 120mm Premium Quiet Fan

The Noctua NF-A12x25 LS-PWM redefines silent airflow with its Low-Speed (LS) optimized design. Featuring Noctua’s renowned SSO2 bearing and precision-tuned blades, this 120mm fan delivers exceptional performance with near-silent operation for noise-sensitive environments.

Advanced Quiet Cooling:

Low-Speed Optimized Design:

Specialized for ultra-quiet operation (900-1500 RPM range) while maintaining excellent static pressure (1.86 mm H₂O). The reduced speed variant operates at just 12.1dB(A) at minimum speed.

Sterrox Liquid-Crystal Polymer:

Advanced LCP blades maintain precise tolerances at all speeds for minimized turbulence. The tight blade-tip clearance reduces vortex noise.

Premium Engineering:

SSO2 Bearing:

Noctua’s second-generation Self-Stabilizing Oil-Pressure bearing ensures 150,000+ hours MTBF with <0.1dB bearing noise.

PWM Control:

4-pin PWM support allows precise speed control from 450 to 1500 RPM. Includes Low-Noise Adapter (LNA) for further speed reduction.

Versatile Application:

FocusFlow Frame Design:

Channeled airflow concentrates pressure on heatsinks and radiators. Ideal for CPU coolers, AIO radiators, and case ventilation.

Anti-Vibration Pads:

Included silicone mounts absorb vibrations for silent case mounting. The SecuFirm2 mounting system ensures secure installation.
