This article covers Cooler Master MasterFan MF120 Halo PCケースファン RGB搭載 シングルファン デュアルループ MFL-B2DN-18NPA-R1 FN1367.

Overview

The Cooler Master MasterFan MF120 Halo (model MFL-B2DN-18NPA-R1, FN1367) is a 120mm case fan featuring dual-loop addressable RGB lighting. It spins up to 1800 RPM and produces 6–30 dBA of noise, balancing cooling performance with quiet operation. A smart fan sensor prevents cable snagging during installation, a thoughtful touch for builders. This fan uses custom-designed blades to generate high static pressure, making it a solid choice for radiators or CPU coolers. The dual-loop RGB design means two independent LED rings (center and outer frame) can light up separately, creating a rich, layered lighting effect. Positioned as an entry-to-mid-range RGB fan, it's sold individually so you can buy exactly the number of fans you need. The combination of visual flair and practical airflow makes it a flexible option for both new builds and upgrades.

Compatibility Guide

Size: Standard 120mm x 120mm x 25mm – fits most PC cases. Power connector: 3-pin (DC control). Motherboard must support DC fan speed control; PWM-only headers will run the fan at full speed. RGB connector: 5V 3-pin addressable RGB (ARGB) header. Compatible with ASUS Aura Sync, ASRock Polychrome Sync, and MSI Mystic Light. No ARGB header on motherboard? You'll need a separate RGB controller (e.g., Cooler Master ARGB controller, sold separately). * Included accessory: ARGB connector clip to bundle cables neatly.

Product Info

Released in early 2020, the MasterFan MF120 Halo typically sells for around ¥2,000–¥2,500 (approx. $15–$20 USD). It comes with a 2-year warranty and is sold as a Cooler Master authorized product. Market positioning: entry-to-mid-range. Its standout feature is the dual-loop RGB lighting, which rivals more expensive fans. Cooling performance is adequate for typical use, including radiators up to 30mm thickness. The single-fan pack format allows flexible purchasing.

Best Use Cases

RGB enthusiasts: The dual-loop lighting creates a dramatic visual effect. Best for users who already have a motherboard with ARGB header – if not, factor in the cost of a controller. Radiator cooling: High static pressure makes it effective on slim radiators (e.g., 240mm AIOs). Users with thick radiators (45mm+) should consider higher-pressure fans. * Budget-conscious builders: Good value for a single ARGB fan. However, those wanting PWM control should look at the PWM version of this fan or alternatives like the Arctic P12 PWM PST ARGB.

Things to Consider

The biggest limitation is the lack of PWM. This fan relies on DC voltage control, which may not be supported by all motherboards in their fan control software. If your motherboard only offers PWM headers, the fan will run at full speed (1800 RPM) unless you use a voltage adapter. RGB requires a 5V ARGB header. It is not compatible with 12V RGB headers. If your motherboard lacks ARGB, an external controller is necessary, adding to the total cost. Noise at maximum speed is noticeable (30 dBA). While not loud, it's not silent. At lower speeds, it's very quiet. Competing fans like the Thermalright TL-C12C-S ARGB offer similar performance at a lower price, but lack the dual-loop effect. Also, the fan is not daisy-chainable for power; each fan requires its own 3-pin header. This can be a headache if your motherboard has limited fan headers. ## FAQ
Q: Can I control the RGB with my motherboard's software? A: Yes, if your motherboard has a 5V ARGB header. It works with ASUS Aura Sync, ASRock Polychrome Sync, and MSI Mystic Light. For other brands, check compatibility. Q: Is this fan PWM? A: No, it uses a 3-pin DC connector. For PWM control, look for the MasterFan MF120 Halo PWM (model MFL-B2DN-18NPA-R2). Q: How many fans can I connect to one ARGB header? A: Most ARGB headers support up to 3 fans (3A max). The MF120 Halo draws 5V/0.6A, so three fans would be 1.8A, which is safe. Always check your motherboard's header limit.
