Single 120 mm case fan for case.

The Cooler Master MasterFan MF120 Halo² is a 120 mm case fan built for standard case, liquid-cooler or air-cooler mounting. It uses a rifle bearing and a 4-pin PWM connector to vary speed from 0 to 2,050 RPM, delivering 51.88 CFM (88.14 m³/h) at a rated 27 dB(A). The black frame measures 25 mm thick and includes enlarged Air Balance blades for improved flow.

Dual-loop ARGB Gen 2 rings and cable clips

Dual-loop addressable RGB rings increase illumination area by 50% and support ARGB Gen 2 effects when connected to a 3-pin 5 V header; the fan defaults to a spectrum cycle if no header is detected. An upgraded driver IC boosts cooling performance while reducing noise. Clips are supplied to secure both PWM and ARGB cables, and an extended 3-pin plug permits daisy-chaining multiple fans.

Check 120 mm mount spacing and 5 V ARGB header

Verify that your chassis or radiator has 120 mm mounting points with 25 mm clearance for the fan thickness. Confirm your motherboard or controller provides a 5 V 3-pin addressable RGB header if you want full Gen 2 control; otherwise the fan will run its default lighting pattern. Ensure the 4-pin PWM header can supply the required current for speed regulation.
