The optimal RPM for a 120mm case fan can vary depending on the specific model and the user's preferred balance between performance and noise level. Generally, fans with higher RPMs provide better cooling performance, but may also be louder.

According to a discussion on the Tom's Hardware forum, typical 120mm case fan run between 1000-3000 RPM, with performance-oriented fans often exceeding 2000 RPM, while quieter models run below 1500 RPM. It is also recommended that instead of focusing solely on RPM, the 120mm case fan's CFM (cubic feet per minute) (indicating airflow) and noise level (measured in decibels (dBA)) should also be considered.
