## Summary description

The Montech RX140 PWM is a 14 cm computer case fan designed for optimal cooling performance. It operates at speeds between 540 and 1760 RPM, utilizing a rifle bearing for enhanced durability and quiet operation. Its sleek white design fits well with modern builds, ensuring efficient airflow and temperature management.

## Long description

The Montech RX140 PWM 14 cm White is a case fan combining a modern hexagonal RGB ring with performance-oriented airflow. It integrates 24 LEDs and supports 5V 3-pin ARGB motherboard connectors for software lighting control. The nine-blade fan and optimized frame are engineered to improve heat dissipation while keeping noise low, and the rifle bearing is specified for long service life. Speed control via PWM allows automatic adjustment between 540 and 1760 RPM to match system temperatures.
Advantages
The RX140 PWM provides customizable RGB illumination through its 24 LEDs and 5V 3-pin connector, stable PWM-driven speed control, and a rifle bearing rated for long durability. Its nine-blade design and tailored frame stabilize airflow for improved cooling performance and reduced noise, while anti-vibration pads minimize resonance. A reverse blade design preserves RGB visibility when used as an intake fan.
Suitable for
PC cases requiring a 140 mm cooling fan
Radiator or case fan setups in gaming and high-performance builds
Systems where ARGB lighting is controlled via 5V 3-pin motherboard headers
Key specifications
Fan size: 140 mm
Speed (PWM): 540–1760 RPM
Bearing type: Rifle bearing, rated ~80,000 hours
LEDs: 24 RGB LEDs, hexagonal ring
Connector: 5V 3-pin ARGB for lighting; standard PWM fan connector for speed control
Noise level: under 27.9 dB(A) at maximum RPM (manufacturer data)
How to use
Install the RX140 PWM into a compatible 140 mm fan slot in your case or onto a 140 mm radiator using the supplied screws. Connect the fan power cable to a PWM-capable fan header on the motherboard to enable automatic speed control. Plug the 5V 3-pin ARGB cable into a matching motherboard header or compatible controller to manage lighting effects via software. Ensure airflow direction matches your desired intake or exhaust configuration; the reverse blade design keeps RGB lighting visible when used as intake.
Usage recommendations
Mount the fan securely using all four screws and use the anti-vibration pads on the frame contact points to reduce noise. For optimal cooling balance, connect to a motherboard PWM header and configure fan curves in BIOS or monitoring software; ensure the 5V ARGB header supports 3-pin 5V devices before connecting lighting.
