ASUS ROG Strix XF120/XF120A1/BK// 120mm case fan

Single 120 mm magnetic-levitation fan

The ASUS ROG Strix XF120 is a 120 mm case fan built around a magnetic-levitation bearing rated for 400000 hours of operation. It spins between 250 and 1800 RPM and delivers 62.5 CFM at a quoted 22.5 dBA. The 4-pin PWM connector allows motherboard speed control without a separate fan controller. It suits builders who want one versatile fan for chassis intake, exhaust, radiator or CPU cooler duty.

MagLev bearing, grooved blades

Magnetic-levitation stabilises the rotor to cut friction and noise, while a minimised blade hub widens the airflow channel. Grooved fan blades and a direct-flow frame reduce turbulence, improving both airflow throughput and static pressure. Anti-vibration pads on the corners dampen vibration transfer to the case, helping the fan stay quiet at higher speeds.

Check 120 mm mounting points and 4-pin PWM header

Verify your case or radiator has 120 mm mounting holes with 25 mm clearance for the fan thickness. Ensure the motherboard or fan hub provides a 4-pin PWM header; the fan will not run from a 3-pin voltage-controlled header without losing speed control. The non-LED black finish suits stealth builds but adds no lighting if you need RGB synchronization.
