NZXT RF-R212S-BF 120mm case fan 2400-2640 RPM 70.67 CFM 3.7 mmAq 33.05 dBA

Black 120 mm PWM fan with 8 addressable RGB LEDs

The NZXT F120 RGB is a 120 mm case fan built around a fluid dynamic bearing and nine blades optimised for static pressure. It spins between 2400 and 2640 RPM, delivering 70.67 CFM airflow at 3.7 mmAq pressure while producing 33.05 dBA. The frame includes clear side windows that showcase eight addressable RGB LEDs driven through a 5 V ARGB connector alongside the standard 4-pin PWM lead.

Suited for radiators and mesh panels needing high

Builders who want strong airflow through dense fin stacks or restrictive front panels will benefit from the high-pressure blade profile and low vibration corners. It is not suited for systems that lack a 5 V ARGB header or NZXT control hub to drive the lighting. Buyers who prefer a fan with an included hardware controller or a different frame colour should look elsewhere.

2400-2640 RPM speed range defines cooling and noise

The PWM curve tops out at 2640 RPM, setting the maximum 70.67 CFM airflow and 33.05 dBA acoustic ceiling. At lower duty cycles the fan runs quieter while still providing useful pressure for radiator or heatsink duty. If the build requires a lower minimum speed or a higher peak airflow figure, this model will not match that requirement.
