NF-A12 x 25 G2 PWM: Powerful and quiet at a great price The NF-A12 x 25 G2 PWM from Noctua is a high-quality 120 mm fan designed for quiet and powerful cooling. Ideal for those who value silent operation and thoughtful engineering including flexible control and extensive accessories. Strong cooling performance with low noise With up to 1.800 rotations per minute, the fan delivers effective airflow and high pressure perfect for tight cooling fins or dense cases. Despite its performance, it remains pleasantly quiet at 22.5 dB(A). For particularly noise-sensitive environments, an adapter is included that reduces the speed to 1.500 RPM at only 18.1 dB(A). Robust housing for smooth operation The housing is made from reinforced liquid crystal polymer, known for its high dimensional stability and low vibration. The special shape of the fan blades reduces air turbulence and contributes to a smooth airflow with quiet and stable running. Durable bearing & smart accessories Noctuas proven bearing ensures reliable operation over many years. Included are a Y-cable for controlling multiple fans, an extension cable, vibration-dampening mounts, and a seal for radiators ideal for flexible installation options and quiet operation.
