Manufacturer description

The Cooler Master MasterFan MF120 Halo2 is a 120mm ARGB case fan that improves on the original MasterFan Halo in both cooling and lighting. Its Air Balance blades are 10% larger than the previous model's. They move 51.88 CFM of air at 2.89 mmH2O of static pressure, so you can use the fan for case intake or exhaust. Noise stays low. A new hybrid frame has corner dampers lined with sound-absorbing material to reduce vibration. An upgraded driver IC limits noise to a rated maximum of 27 dBA and raises top speed. The fan uses 4-pin PWM control across 0-2050 RPM (plus or minus 5%), so your…

Frequently Asked Questions

Can I control the MF120 Halo2 lighting with my motherboard software?

Yes. The lighting works with ARGB motherboard software such as ASUS Aura, ASRock RGB and MSI RGB. Cooler Master includes ARGB connector clips that keep the plug firmly attached to the header.

How loud is the Cooler Master MF120 Halo2?

Its rated maximum noise is 27 dBA. The fan runs from 0 to 2050 RPM (plus or minus 5%) on 4-pin PWM, so it can stay slower and quieter at idle. The hybrid frame's sound-absorbing corner dampers also reduce vibration.

Is this fan better for case airflow or for a radiator?

Its specs are 51.88 CFM of airflow and 2.89 mmH2O of static pressure, and Cooler Master markets it for case intake and exhaust. For radiator use, compare that pressure figure with your cooler maker's recommendations.

What does the jam sensor protection do?

The MF Halo series has smart sensors that help protect against cables and components getting caught or damaged while the fan runs. This is useful in tight builds where wires sit close to the blades.

What changed from the original MasterFan Halo to the Halo2?

The Halo2 has 10% larger Air Balance blades, larger LED rings rated 50% more vibrant, and an upgraded driver IC for lower noise and higher RPM. It also adds a hybrid frame with corner dampers. It keeps the original's smart fan sensor, rifle bearing and ARGB software compatibility.
