Ventilatormodule Montech AX120 PWM 120mm 12V 3-pin 4-pin wit

The Montech AX120 PWM is a 120mm fan module in white designed to provide efficient system cooling with customizable RGB lighting. It integrates a hexagonal RGB ring with 20 LEDs and supports 5V 3-pin motherboard connectors for software control. The fan is compatible with standard case and radiator mounts and offers both 3-pin and 4-pin connectivity for flexible installation in a variety of PC builds.

Advantages

The AX120 PWM combines a modern aesthetic with practical cooling performance: a nine-blade fan geometry stabilizes airflow to improve heat dissipation while reducing operational noise. PWM control enables automatic speed adjustment between 800 and 1600 RPM based on motherboard temperature sensing. The fan uses a rifle bearing rated for up to 80,000 hours and features eight rounded anti-vibration pads to minimize vibration and resonance. Available as a single pack or a 3-in-1 set, it supports both 3-pin and 4-pin connections.

How to use

Install the AX120 PWM in a standard 120 mm fan mounting position in your case or on a radiator using the supplied screws. Connect power and control to the motherboard using either the 3-pin or 4-pin connector depending on your board and desired control method; for software RGB control connect the 5V 3-pin ARGB header. When connected to a PWM-capable 4-pin header, the fan speed will be automatically adjusted by the motherboard according to temperature. Ensure the fan is oriented for the intended airflow direction and secure anti-vibration pads contact the chassis to reduce noise.

Recommendations

For quieter operation, enable PWM fan curves in your motherboard BIOS or control software and place the fan to optimize airflow intake or exhaust. Clean the fan blades periodically to maintain cooling efficiency and check mounting screws for tightness to preserve vibration damping.
