Noctua NF-A12x25 ULN 120mm Ultra-Low-Noise Case Fan

The Noctua NF-A12x25 ULN 120mm Fan delivers whisper-quiet operation for silent PC builds, featuring Noctua’s renowned engineering excellence in an ultra-low-noise optimized version of their flagship 120mm fan.

Ultra-Quiet Performance:

Silent-Optimized Design:

The NF-A12x25 ULN combines Noctua’s advanced AAO frame technology with a reduced maximum RPM to achieve near-silent operation. The precision-engineered blades and tight tolerances minimize turbulence noise while maintaining excellent airflow for its noise level.

With a maximum speed of just 1200 RPM (compared to 2000 RPM on the standard version), this ULN model operates at exceptionally low noise levels while still providing sufficient airflow for most silent PC configurations.
