PHANTEKS case fan 140mm M25G2-140 D-RGB Reverse Blade PWM PH-F140M25R_G2_DBK01

PHANTEKS M25G2-140 D-RGB Reverse Blade PWM is a 140mm chassis and radiator fan that combines a reverse-blade aerodynamic design with addressable RGB lighting and PWM speed control. The fan is built to mount in standard 140mm locations inside gaming PCs and workstations, delivering directed airflow to help lower component temperatures while providing customizable illumination that integrates with compatible RGB controllers.

Advantages

The reverse-blade geometry is engineered to improve static pressure and focused airflow across radiators and dense fin stacks, while PWM control enables precise speed adjustments between quiet idle and higher cooling demand. Addressable D-RGB lighting offers per-LED color control for synchronized system lighting. The fan features a durable frame and blade construction to ensure stable operation and long service life under continuous use.

Suitable for

• Case ventilation in mid-tower and full-tower PC builds
• Radiator cooling for air-to-liquid or AIO liquid-cooling setups
• Workstation systems requiring sustained airflow and temperature management
• Builds where synchronized addressable RGB lighting is desired

Key specifications

• Fan size: 140 mm
• Blade design: Reverse/blade geometry optimized for pressure and directed airflow
• Speed control: PWM (pulse-width modulation) for variable fan speed
• Lighting: Addressable D-RGB per-LED control compatible with standard ARGB headers
• Mounting: Standard 140 mm mounting pattern for chassis and radiators
• Connector types: PWM power connector and D-RGB lighting connector (addressable)

How to use

Install the fan into any standard 140 mm mounting position in your chassis or onto a compatible 140 mm radiator using the supplied screws or appropriate fasteners. Connect the 4-pin PWM cable to a motherboard or fan controller header that supports PWM control to enable automatic speed regulation. Attach the addressable D-RGB connector to a compatible ARGB header or controller and configure lighting through the system software or external controller. Ensure airflow direction aligns with your case airflow plan to achieve optimal cooling performance.

Recommendations

For radiator installations, place the fan so that the reverse-blade orientation pushes air through the radiator for improved static pressure performance. Use motherboard fan curves or a dedicated fan controller to balance noise and cooling, and verify ARGB compatibility with your motherboard or controller to enable full lighting control.
