NF-A12 x 25 G2 PWM: Powerful and quiet at a great price With the NF-A12 x 25 G2 PWM, Noctua offers a high-quality 120 mm fan 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 revolutions per minute, the fan delivers effective airflow and high pressure perfect for tight cooling fins or dense cases. Despite the performance, it remains pleasantly quiet at 22.5 dB(A). For particularly noise-sensitive environments, an adapter is included that lowers 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 operation. Durable bearing & clever accessories Noctuas proven bearing ensures reliable operation for 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.
