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

The Montech AX120 PWM is a 120mm black fan module designed for PC cooling. It supports both 3-pin and 4-pin (PWM) connectors and operates at 12V. The fan integrates 20 LEDs with a hexagonal RGB ring and supports 5V 3-pin motherboard connectors for software-controlled lighting. Its nine-blade design, optimized frame and vibration-damping pads provide balanced airflow, reduced noise and long-term reliability for case, radiator, and CPU cooling applications.

Advantages

The AX120 PWM combines RGB lighting customization with PWM automatic speed control, allowing fan speed adjustment between 800 and 1600 RPM. The fan uses a rifle bearing rated for up to 80,000 hours, features eight rounded anti-vibration pads to reduce resonance noise, and maintains noise levels under 27 dB(A) at maximum speed. Available in single or 3-in-1 pack options, it fits common PC builds and radiator mounts.

Key specifications

How to use

Install the AX120 PWM into a compatible 120 mm fan mount in your case or radiator bracket using standard fan screws. Connect the power and speed control cable to a 4-pin PWM header for automatic speed regulation by the motherboard, or to a 3-pin header for fixed-voltage operation. For RGB lighting control, connect the 5V 3-pin RGB cable to a compatible motherboard RGB header and use motherboard software to select lighting modes.

Recommendations

For optimal performance, mount the fan so airflow matches your system’s intake and exhaust balance, keep fan blades and surrounding filters clean, and use PWM control for temperature-responsive cooling. Choose a 3-pack if you plan multiple-fan radiators or case intake/exhaust arrays.
