The Snowman BM-MK120 is a 120 mm case cooling fan designed to improve airflow inside desktop PC cases while adding RGB lighting effects for gaming builds. It features a hydraulic bearing that provides smoother rotation, quieter performance, and longer lifespan compared with basic sleeve bearings.
The fan typically operates between 800 and 1600 RPM, delivering airflow around 45 CFM while maintaining a low noise level near 19 dB, making it suitable for budget gaming PCs or general desktop cooling.
It supports 3-pin motherboard connection or Molex power from the PSU, allowing flexible installation even on older motherboards without dedicated fan headers. The 120 mm size (120 × 120 × 25 mm) fits most ATX, micro-ATX, and mini-ITX cases.
