120 mm ARGB Case Fan for PWM Builds

The Montech AX120 PRO is a 120 mm case fan with addressable RGB lighting and a 4-pin PWM connector. It targets builders who want adjustable cooling and synchronised lighting inside a standard chassis. The rifle bearing and black frame suit both intake and exhaust positions.

Straightforward PWM and 5 V ARGB Install

Mount the fan using the four corner holes with standard screws. Connect the 4-pin PWM header for speed control and the 5 V 3-pin ARGB header for lighting sync. The only common issue is reversing the ARGB plug orientation, which leaves the LEDs dark until corrected.

72.3 CFM Airflow at 25.4 dBA Peak

At 1600 RPM the fan delivers 72.3 CFM while peaking at 25.4 dBA, giving ample headroom for mid-range CPU and GPU thermals. Running at the 600 RPM floor keeps noise near inaudible but limits heat removal on heavily overclocked components.

Questions about this item

How can I confirm the AX120 PRO is running at the intended 600-1600 RPM after installation?

Monitor the fan speed in your motherboard BIOS or fan-control software; it should report between 600 and 1600 RPM with a tolerance of roughly ten percent.

Does the AX120 PRO package include both the PWM 4-pin and ARGB 5V 3-pin cables, or must I buy either separately?

The fan has both connectors built in; the 4-pin PWM header powers and controls speed while the 5V 3-pin header drives the addressable RGB lighting.

The listing shows a single black 120 mm model — are there other colour or size versions I should consider?

Only the black 120 mm variant appears in the supplied data; no alternative colours or frame sizes are listed for this PRO model.
