120mm RGB case fan

The NZXT F120 RGB Core is a 120mm case fan designed for builders who want addressable lighting and reliable airflow in a single unit. It suits PC enthusiasts assembling custom loops or air-cooled towers where visual customisation matters. Buyers needing multiple fans in one pack or a non-RGB alternative should look elsewhere.

Fluid dynamic bearing with 500–1,800 RPM range

The fan uses a fluid dynamic bearing rated for 60,000 hours and spins between 500 and 1,800 RPM with a tolerance of 180 RPM. This bearing choice determines long-term acoustic consistency and rotational stability more than any other specification. The 4-pin PWM connector allows the motherboard to regulate speed automatically.

33.88 dBA at 78.86 CFM airflow

In normal operation the fan produces 33.88 dBA while moving 78.86 CFM of air through its 26mm-thick frame. Eight individually addressable LEDs are diffused by semi-translucent blades, adding illumination without increasing audible output. Anti-vibration rubber corners further suppress resonance when mounted as intake or exhaust.

Questions about this item

What does the 78.86 CFM airflow figure mean for actual case cooling?

That airflow rating shows the fan can move a strong volume of air through a case or radiator at full speed, helping lower component temperatures during heavy loads.

How does the 4-pin PWM connector limit or enable speed control?

The 4-pin PWM header lets the motherboard or a fan controller vary the fan speed precisely between 500 and 1,800 RPM, so the fan runs only as fast as needed for the current temperature.

Will the 26 mm thickness fit standard 120 mm mounting points in my case?

Yes, the fan uses the standard 120 mm square frame with 26 mm depth, matching typical case and radiator mounting holes without clearance issues.
