Montech RX140 PWM REVERSE Fan 140mm ARGB Black

Montech RX140 PWM REVERSE is a 140 mm case fan that combines high airflow and addressable RGB lighting in a black, clean chassis. The reverse rotation direction is designed specifically for situations where you want the RGB to face outward, rather than towards the frame or radiator. With up to 1600 RPM, airflow of 90.50 CFM, and static pressure of 2.90 mmH2O, this fan easily takes on the role of a primary intake or exhaust in mid and larger cases. Add in a rifle bearing with 60000 hours MTBF and you get stable, long-lasting cooling.

What you get

With a range of 600 to 1600 RPM, you can adjust the RX140 from nearly silent mode to aggressive cooling when needed, without exceeding 27.9 dBA noise. The airflow of 90.50 CFM and pressure of 2.90 mmH2O mean that the fan performs well on both mesh front panels and more closed fronts or filters. The reverse rotation is key if you want a “clean” ARGB view in intake mounting – the blades and lighting face you, not the grille. The rifle bearing and 12 V power supply through a 4-pin PWM connector allow for smooth RPM control via the motherboard, while anti-vibration pads help reduce vibrations and additional noise. The cable length of 500 mm provides freedom in routing even in larger cases.

• Size 140 x 140 x 25 mm – larger fan compared to 120 mm models for more air at similar RPMs.
• RPM 600–1600 – wide range for quiet everyday mode and more aggressive cooling during gaming or summer heat.
• Airflow 90.50 CFM and pressure 2.90 mmH2O – good combination for front intake, top exhaust, or operation behind filters.
• Noise level 27.9 dBA – balanced sound for a 140 mm fan with high CFM.
• Rifle Bearing with 60000 hours MTBF – longer life and smoother operation compared to cheap sleeve bearings.
• Reverse rotation direction – optimal RGB presentation when the fan is mounted to intake air into the interior but shows the lighting outward.
• 4-pin PWM + 3-pin 5V ADD-RGB connectors – full control of RPM and synchronization of ARGB with the motherboard or controller.
• Anti-vibration pads and black color – less vibration and easy integration into almost any build.
• 36 months warranty – peace of mind for long-term operation in your main machine.

Who is it suitable for

RX140 PWM REVERSE is a good choice if you are building an ARGB setup and want a fan that looks good from the “right” side in an intake configuration without sacrificing airflow. It is suitable for gaming cases with space for 140 mm fans, where you seek a balance between cooling and noise, plus flexibility in control via PWM. If you are aiming for a completely silent system under full load, you will need to play with the fan curves or combine it with other fans for lower individual RPMs.

The combination of 140 mm format, high CFM, reverse design, and addressable RGB makes this Montech fan very practical for modern, visually open builds where both cooling and aesthetics carry equal weight.
