Product Identity

The Cooler Master MasterFan MF120 Halo 3-pack delivers three 120 mm case fans with hybrid static-pressure blades and dual-ring addressable RGB lighting. Each fan runs at 650 to 1800 RPM and moves up to 47.2 CFM while staying between 6 and 30 dBA. A wired ARGB controller and splitter cable are included for immediate setup.

Who It Suits

Builders who want coordinated lighting across three positions and a single hardware controller will find this kit convenient. The rifle-bearing design and noise-reduction materials suit quiet-focused systems. Buyers who need larger 120 mm variants, different colour frames, or motherboard-only lighting control without an extra controller should look elsewhere.

Deciding Specification

The 24 individually controlled ARGB LEDs per fan create the dual-ring lighting effect that defines this model. This LED count determines whether the visual density matches your aesthetic goal.

Questions about this item

How can I confirm the fans are spinning at the correct speed after installation?

Use your motherboard BIOS or fan-control software to verify each fan reports between 650 and 1800 RPM under load.

What comes in the box and what must I purchase separately?

The package includes three 120 mm fans, 12 mounting screws, two ARGB holsters, a wired ARGB controller, an ARGB power cable, a fan power splitter and a manual; no extra parts are required for basic operation.

Which version should I choose if I want addressable RGB lighting with a hardware controller?

This MFL-B2DN-183PA-R1 3-pack already provides 24 individually controlled ARGB LEDs per fan and includes the wired ARGB controller for button-based colour changes without software.
