Montech AX140 PWM is a 140 mm computer case fan designed for case ventilation, radiator and CPU cooler use. The white finish suits light-coloured builds. It offers a PWM-controlled speed range of 540–1760 RPM, rifle bearing durability and an ARGB hexagonal lighting ring compatible with 5V 3-pin motherboard headers for software customization.

Advantages

The fan integrates 24 LEDs within a hexagonal RGB ring to provide customizable lighting effects while supporting motherboard 5V 3-pin control. Its nine wing-shaped blades and optimized bending angles stabilize airflow for improved heat dissipation and reduced noise. The rifle bearing extends service life up to 80,000 hours and, together with eight rounded anti-vibration pads, reduces noise and vibration during operation. Even at maximum RPM the noise level remains under 27.9 dB(A).

Key specifications

How to use

Mount the AX140 PWM to the case, radiator or cooler using the standard 140 mm mounting holes. Connect the 4-pin PWM power cable to the motherboard fan header to enable automatic speed control based on system temperature. Attach the 5V 3-pin ARGB connector to a compatible motherboard header or controller to enable software lighting control. Ensure the airflow direction matches your desired intake or exhaust orientation and secure the fan to minimise vibration.

Recommendations

For optimal cooling balance, configure the AX140 PWM as intake and exhaust fans according to your case airflow plan and control fan curves via motherboard BIOS or software. Periodically clean the fan blades and ARGB ring to maintain airflow and lighting quality.
