Model MF120 Halo²

  • Dual-loop ARGB rings boost illumination by 50%
  • Enlarged Air Balance blades increase airflow by 10%
  • Hybrid frame keeps stability without shrinking blade area
  • Upgraded driver IC cuts noise while raising cooling
  • PWM control spans 0 to 2,050 RPM for silent or max flow

Target use

The MasterFan MF120 Halo² White is a 120 mm case fan built for PC cases, liquid coolers or air coolers. It suits builders who want addressable RGB lighting and adjustable cooling in a white colour scheme. Buyers needing fans larger than 120 mm or a non-LED model should look elsewhere.

Installation notes

The fan uses a standard 4-pin PWM connector for power and a 3-pin addressable RGB header for lighting control. Included cable clips help secure connections and simplify routing. The hybrid frame fits typical 120 mm mounting points, but builders with unusually tight clearance should verify spacing before fitting.

Compatibility check

Confirm your motherboard or controller provides a 4-pin PWM header and a 3-pin 5 V addressable RGB header for full lighting customisation. The fan operates between 0 and 2,050 RPM with a maximum noise level of 27 dB(A) and delivers 51.88 CFM of airflow. Ensure your case accepts 25 mm thick fans at the intended mounting locations.

Frågor om den här produkten

How can I verify the MasterFan MF120 Halo² is running at the correct 2050 RPM maximum after installation?

Use BIOS or fan-control software to read the 4-pin PWM signal; the fan should report speeds up to 2050 RPM ±5 % under full load.

What accessories are included with the single white 120 mm fan and what must I supply myself?

The box contains one fan with pre-attached 4-pin PWM and 3-pin ARGB cables plus cable-securing clips; you must provide a motherboard 4-pin fan header and a 3-pin 5 V ARGB header or controller.

Which version of the MF120 Halo² should I choose for a white-themed build that needs 51.88 CFM airflow?

This MFL-B2DW-21NP2-R2 model is the white 120 mm variant delivering 51.88 CFM at 27 dB(A); no other colour or capacity versions exist for this part number.
