Noctua NF-A12x25 G2 PWM chromax.black Gehäuseluefter 120 mm chromax Black

The NF-A12x25 G2 PWM chromax.black pushes the boundaries of 120mm fan engineering with Noctua's latest Sterrox® LCP construction and an all-black stealth aesthetic. Building on the legendary NF-A12x25, this second-generation model refines the blade geometry and hub design to deliver even better airflow-to-noise efficiency, making it the definitive choice for high-end air cooling, radiators, and case ventilation.

Highlights

• All-black chromax.black design with included anti-vibration pads for seamless integration into any build
• Sterrox® liquid-crystal polymer impeller with ultra-tight tip clearance for superior pressure and airflow
• SSO2 self-stabilising oil-pressure bearing with metal bearing shell for exceptional long-term stability
• PWM control with wide speed range from 450 to 2000 RPM for automatic motherboard-based speed adjustment
• Includes Low-Noise Adaptor, extension cable, Y-cable, and mounting screws for versatile installation

In daily use

Whether cooling a dense fin stack or simply moving air through a performance chassis, the NF-A12x25 G2 PWM chromax.black remains virtually inaudible at low speeds while ramping up smoothly under load. The 4-pin PWM interface lets your motherboard or fan controller fine-tune the speed in real time, so you get maximum cooling when needed and near-silent operation when idle. The included Low-Noise Adaptor reduces the top speed to approximately 1700 RPM for users who prioritise absolute quietness, while the anti-vibration pads and premium bearing eliminate distracting motor noise and resonance.
