Fan Thermalright Peerless Assassin 120 12 cm 1550 RPM White
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.
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.
Install the fan on a compatible CPU cooler or mounting bracket aligned with the airflow direction marks, secure it with the appropriate screws or clips, and connect the power cable to the motherboard fan header. Ensure the fan is oriented to provide intake or exhaust airflow according to your case cooling layout. Verify BIOS or software fan control settings to set automatic or manual speed profiles.
For optimal cooling, pair this 120 mm fan with a compatible heatsink designed for AM4/AM5 processors and maintain regular cleaning to prevent dust buildup. If lower noise or higher airflow is required, consider configuring fan curves in BIOS or using an additional fan in a push-pull arrangement.
