Fan Montech RX120 PWM 12 cm 800-1600 RPM 27 dB White

The Montech RX120 PWM is a 120 mm system cooling fan designed for case, radiator, and general PC ventilation. It features a hexagonal RGB ring with 20 LEDs and supports 5V 3-pin motherboard RGB headers for software lighting control. The fan operates between 800 and 1600 RPM, delivers up to 59 CFM airflow, and uses a Hydro Dynamic Bearing (HDB) for extended service life and reduced noise. The white finish and reverse blade design allow visible RGB lighting when used as an intake fan while maintaining compatibility with standard 120 mm mounts.

Advantages

The RX120 PWM combines customizable RGB lighting and PWM-based speed control to balance cooling performance and acoustics. Optimized nine-blade geometry stabilizes airflow and improves heat dissipation while minimizing turbulence and noise; measured noise remains under 27 dB(A) even at maximum speed. The HDB bearing provides a long operating lifespan (approximately 40,000 hours) and lower vibration is achieved through eight integrated rounded anti-vibration pads. The reverse fan blade design enhances RGB visibility without sacrificing airflow.

Suitable for

• PC case cooling (120 mm mounts)
• Radiator fans for liquid cooling loops
• High-performance or gaming system builds
• Systems requiring quiet operation and RGB lighting

How to use

Install the RX120 PWM into any standard 120 mm fan mount in your case or on a compatible radiator using the supplied screws. Connect the 4-pin PWM power connector to the motherboard fan header to enable automatic speed control based on system temperature. Attach the 5V 3-pin RGB cable to a compatible motherboard RGB header or controller to manage lighting modes via motherboard software. Ensure airflow orientation matches your intended intake or exhaust configuration; the reverse blade design allows good RGB visibility when used as intake.

Recommendations

For optimal performance, position the fan to match your case airflow layout, keep fan and radiator surfaces free of dust, and let the motherboard control fan curves for a balance of cooling and low acoustic output. Use compatible 5V 3-pin RGB headers for full lighting control.
