White 120 mm case fan for RGB builds

The Cooler Master MasterFan MF120 Halo White Edition is a single 120 mm case fan finished in white. It targets builders who want addressable RGB lighting on both sides of the blade and need a fan that fits standard 120 mm mounting points. The unit ships with four screws and an ARGB holster for cable management.

Rifle bearing with rubber pads and PWM control

A rifle bearing and sound-absorbing rubber pads on the corners reduce vibration transferred to the chassis. The 4-pin PWM connector allows the motherboard to vary speed between 650 and 1800 RPM, so the fan runs quietly at idle and ramps up only when thermal load demands it. No separate fan controller is included or required.

47.2 CFM static-pressure airflow for radiators

The hybrid blade design delivers 47.2 CFM with a focus on static pressure, making the fan suitable for CPU liquid-cooling radiators or restrictive mesh panels. Noise stays between 6 and 30 dBA across the speed range. Buyers who need higher airflow volume for open-air cases or who want a multi-fan kit with a bundled controller should look elsewhere.

Questions about this item

What does the 4-pin PWM connector let the motherboard control on this fan?

The 4-pin PWM connector allows the motherboard to vary the fan speed dynamically between 650 and 1800 RPM, so the system can minimise noise at idle or maximise airflow under load.

What mounting hardware is included to secure the 120 mm by 120 mm by 25 mm frame?

The box contains four mounting screws and an anti-loose clip that keeps the power connection from working free during vibration.

How do I connect the addressable RGB lighting so it syncs with my motherboard software?

Plug the supplied ARGB holster into a 5 V 3-pin addressable RGB header on the motherboard, then enable the device in Aura Sync, Mystic Light or Polychrome Sync to control the 24 individually addressable LEDs.
