ventilator Montech RX120 PWM 12 cm zwart 720–1760 RPM Rifle Bearing

The Montech RX120 PWM 12 cm fan is designed for system cooling with a modern aesthetic. It integrates 20 LEDs in a hexagonal RGB ring on the frame and supports 5V 3-pin motherboard connectors for software lighting control. The black 120 mm fan uses a rifle bearing for extended lifespan and operates across a PWM-controlled speed range suitable for case, radiator, or general airflow use.

Advantages

The RX120 PWM offers customizable RGB lighting with multiple modes and motherboard software control. Its nine-blade design and optimized blade angles stabilize airflow to improve heat dissipation while reducing noise. PWM automatic control enables dynamic speed adjustment between low and high RPM based on motherboard temperature. The rifle bearing provides long durability, and integrated rounded anti-vibration pads reduce resonance and vibration noise. A reverse fan blade design preserves RGB visibility when used as an intake fan.

Suitable for

• Case cooling for mid-tower and full-tower builds
• Radiator fans in liquid-cooling loops
• Replacing or upgrading existing 120 mm case fans
• Systems where RGB lighting synchronized with motherboard software is desired

Key specifications

• Type: Fan
• Fan diameter: 120 mm
• Colour: Black
• Bearing: Rifle bearing
• Speed control: PWM (approx. 720–1760 RPM according to product data)
• LEDs: 20 integrated LEDs in hexagonal RGB ring
• Connector: 5V 3-pin for RGB control and PWM power connector

How to use

Install the RX120 PWM into a compatible 120 mm fan mounting location in a PC case or on a radiator using standard fan screws. Connect the fan power cable to a motherboard PWM fan header to enable automatic speed control. Connect the 5V 3-pin RGB cable to a compatible motherboard RGB header to control lighting from motherboard software. Ensure correct airflow orientation depending on intake or exhaust placement.

Recommendations

For quiet operation, allow the motherboard PWM control to manage fan speed and place the RX120 PWM where unobstructed airflow is available. When used as an intake fan, the reverse blade design helps preserve RGB visibility; secure anti-vibration pads contact points to minimize noise from resonance.
