## Summary description

The Montech RX140 PWM is a 14 cm computer case fan that operates at 540 to 1760 RPM. It features a rifle bearing for quiet operation and a sleek black design, ensuring efficient airflow and noise reduction for various PC builds.

## Long description

Montech RX140 PWM is a 140 mm case fan with a black frame, designed to combine efficient airflow, low noise and customizable RGB lighting. The fan integrates 24 LEDs in a hexagonal RGB ring and supports 5V 3-pin motherboard connectors for software control, allowing synchronized lighting across compatible systems. Featuring a rifle bearing and a nine-blade design, the RX140 PWM is intended for stable, long-lasting operation in cases, on radiators, or as chassis cooling.
Advantages
The RX140 PWM offers adjustable PWM control from approximately 600 RPM up to 1600–1760 RPM (depending on system conditions) to match cooling needs while keeping noise levels low. Its blade geometry and frame reduce turbulence for improved heat dissipation and quieter operation, with noise measured under 27.9 dB(A) at high speed. A durable rifle bearing provides an extended service life (rated around 80,000 hours), and eight integrated rounded anti-vibration pads reduce resonance and vibration transfer. The reversed blade design preserves RGB visibility when the fan is used for intake.
Suitable for
PC cases requiring 140 mm fans
Radiator cooling in liquid-cooled systems
Silent or low-noise gaming and workstation builds
Systems where synchronized 5V 3-pin RGB control is desired
Key specifications
Size: 140 mm
Speed range: ~540–1760 RPM (PWM-controlled; practical control range ~600–1600 RPM)
Bearing type: Rifle bearing (rated ~80,000 hours)
LEDs: 24 LEDs, hexagonal RGB ring
Noise level: ≤ 27.9 dB(A) at high speed
Connector: PWM power connector + 5V 3-pin addressable RGB header support
Anti-vibration: 8 rounded pads integrated in frame
How to use
Install the RX140 PWM in any 140 mm mounting location in your PC case or on a compatible radiator using the supplied screws. Connect the main fan power to a PWM-capable 4-pin header on the motherboard to enable automatic speed control based on system temperature. For RGB lighting control, connect the 5V 3-pin addressable RGB cable to a compatible motherboard header and use the motherboard’s software to select lighting modes and synchronization. Ensure the airflow direction matches your intended intake or exhaust configuration; the reversed blade design preserves RGB visibility when mounted as an intake.
Usage recommendations
For balanced cooling and acoustics, use motherboard fan curves to let PWM control adjust speeds automatically, and mount the fan with anti-vibration pads against the case to minimize resonance. When installing multiple RX140 fans, connect RGB headers to a controller or compatible motherboard header that supports addressable 5V 3-pin lighting to ensure synchronized effects.
