120mm Rifle Bearing Fan

The Montech AX120 PRO is a 120mm case fan built with a rifle bearing for extended durability. It targets system builders who want a white ARGB accent and reliable airflow in a standard mounting footprint. The unit connects through a PWM 4-pin header for speed control and a 5V 3-pin ARGB header for lighting synchronisation.

Sustained Airflow at 1600 RPM

Under continuous load the fan spins up to 1600 RPM and moves 72.3 CFM of air across heatsinks or radiator fins. The PWM curve keeps the impeller at the required speed without hunting, so cooling performance remains steady during long rendering or gaming sessions. Minimum speed sits at 600 RPM for lighter workloads.

25.4 dBA at Full Speed

At maximum RPM the acoustic output measures 25.4 dBA, keeping system noise low even when the fan is pushed hard. Power draw stays modest thanks to the 4-pin PWM interface, and the rifle bearing maintains consistent rotational stability over time. The white frame and ARGB LEDs add visual flair without increasing thermal load.

Questions about this item

How loud is the Montech AX120 PRO at its maximum 1600 RPM speed?

The fan reaches 25.4 dBA at full speed, a level generally considered quiet enough for background use in a typical room.

Does the Montech AX120 PRO require a motherboard with both a 4-pin PWM header and a 5V 3-pin ARGB header?

Yes, the fan uses a 4-pin PWM connector for speed control and a separate 5V 3-pin ARGB connector for lighting; both headers are needed for full function.

Will the 120 mm frame and 25 mm thickness fit in the same mounts as my older 120 mm fans?

The fan measures 120 x 120 x 25 mm, matching the standard mounting pattern used by most 120 mm fans from previous years.
