Ideal for CPU coolers and case intake

The MasterFan MF120R RGB is a 120 mm PWM case fan designed for CPU liquid-cooler radiators of 120, 240 or 360 mm and for chassis intake positions. It connects via a standard 4-pin header and includes four mounting screws. RGB lighting requires a motherboard or controller with a 12 V 4-pin RGB header, which is not supplied.

Sustained-load behaviour

Under continuous operation the fan delivers 15 to 20 CFM of airflow while the rifle bearing is rated for 280,000 hours of service life. Noise-cancelling technology keeps acoustic output at 31 dBA even during heavy workloads, and a jam-protection feature stops the blades safely if an obstruction occurs.

Build and daily use

The hybrid blade geometry balances static pressure and airflow for radiator and intake duties alike. A 4-pin PWM connector allows precise speed control through the motherboard, while the 12 V RGB header enables synchronisation with Asus Aura, ASRock RGB, Gigabyte Fusion and MSI RGB software. The 25 mm thickness fits standard 120 mm mounting points.

Questions about this item

How loud is the MasterFan MF120R RGB when it runs at full speed all day?

The fan reaches 31 dBA at maximum RPM thanks to its rifle bearing and noise-cancelling design, keeping noise low even under continuous load.

What must I already own to use the RGB lighting on this fan?

You need a motherboard or separate controller with a 12 V 4-pin RGB header; the fan’s RGB cable plugs directly into that header.

Will the MF120R RGB fit on my older 240 mm liquid-cooler radiator?

Yes, the 120 mm frame and standard mounting holes match 120, 240 and 360 mm radiators, so it works as a drop-in replacement.
