Cooler Master MFL-B2DN-213P2-R2 MasterFan MF120 Halo² ARGB Fan

The Cooler Master MasterFan MF120 Halo² (MFL-B2DN-213P2-R2) is a second-generation 120mm case fan that elevates both cooling performance and RGB aesthetics. The headline improvement is the dual-loop ARGB ring system, which uses larger LED rings to deliver 50% greater brightness than the original Halo series. Paired with frosted fan blades that diffuse light more evenly, the result is a vibrant, customizable glow that avoids the harsh hotspot look of many competing RGB fans. The ARGB lighting is fully addressable and compatible with major motherboard lighting ecosystems for synchronized, software-controlled effects.

On the performance side, Cooler Master has enlarged the Air Balance fan blades by 10%, translating to measurably improved airflow over the previous generation. The dynamic PWM control — connected via a standard 4-pin header — lets you dial the fan from a completely silent 0 RPM all the way up to 2,050 RPM, giving you granular control over the noise-to-cooling tradeoff. The redesigned hybrid frame improves both structural rigidity and ease of installation, making it straightforward to mount in standard 120mm fan positions. At just 27 dB maximum noise and a modest 3.5-watt power draw, the MF120 Halo² strikes a practical balance between eye-catching illumination and effective, quiet cooling for enthusiast PC builds.
