## Long description

120 x 120 x 25 mm white processor fan designed for AM4 and AM5 sockets. The compact 12 cm fan delivers airflow while maintaining low noise and uses a sealed precision fluid dynamic bearing for improved longevity. Supplied as a single unit weighing approximately 135 g, it is intended for cooling PC processors in desktop systems.
Advantages
The fan provides a balance of airflow and low acoustic level, operating at up to 1550 RPM and producing around 25.6 dB of noise. Its sealed precision FDB (fluid dynamic bearing) reduces wear and extends service life, and the standard 120 mm size ensures compatibility with typical CPU cooler mounts. The white color allows for a neutral aesthetic integration into most builds.
