The Noctua NF-A12x25 LS-PWM is the low-speed edition of Noctua’s flagship 120mm fan, designed specifically for users who prioritize ultra-quiet operation without compromising build quality or thermal efficiency. Using the same advanced Sterrox® LCP blade design, SSO2 bearing, and precision frame geometry as the standard NF-A12x25, this model is optimized for near-silent performance in low-noise builds, HTPCs, and acoustically sensitive workstations.

Key Features:

Max speed of 1200 RPM for silent airflow under PWM control

Sterrox® liquid-crystal polymer construction with ultra-tight tolerances

SSO2 bearing system for superior long-term silence and durability

Flow Acceleration Channels and stepped inlet design to reduce noise artifacts

Ideal for passive or semi-passive systems where silence is critical
