PHANTEKS case fan M25G2-140 D-RGB 140mm White

PHANTEKS M25G2-140 D-RGB 140mm White is a 140 mm PC case fan with addressable D-RGB lighting designed for system cooling and visual customization. It fits standard 140 mm fan mounts and can be used as a chassis intake, exhaust, or on radiators. The fan combines steady airflow and low noise operation with addressable RGB elements compatible with motherboards that support ARGB control, enabling synchronized lighting effects and individual LED control.

Advantages

The fan provides balanced airflow suited to typical desktop and gaming systems while maintaining low acoustic levels due to optimized blade geometry. Addressable D-RGB lighting allows per-LED color control and integration with popular motherboard software, offering flexible visual configuration. Its 140 mm size improves static pressure and airflow compared to smaller fans, which is useful for dense radiators and restricted front-panel intakes.

Suitable for

• Case cooling for gaming PCs and workstations
• Intake or exhaust installation in mid-tower and full-tower cases
• Mounting on 140 mm radiators for liquid cooling setups
• Systems requiring addressable RGB effects and motherboard synchronization

Key specifications

• Size: 140 mm fan frame compatible with standard 140 mm mounts
• Lighting: Addressable D-RGB (individually controllable LEDs)
• Color: White frame and blades
• Function: Designed for chassis airflow and radiator use
• Compatibility: Works with motherboards supporting addressable RGB headers

How to use

Install the fan into a compatible 140 mm mounting location within the case, orienting the airflow direction according to desired intake or exhaust configuration. Connect the 3- or 4-pin power header as required by the fan model and attach the addressable RGB connector to the motherboard ARGB header to enable lighting control. Ensure screws are tightened evenly to prevent vibration and route cables to avoid contact with blades and other moving parts. After installation, configure fan speed curves and lighting profiles in the motherboard or controller software for optimal cooling and synchronized lighting.

Usage recommendations

For optimal thermal performance, pair the PHANTEKS 140 mm fan with similarly sized intake/exhaust fans to establish a balanced airflow path. When mounting on radiators, verify clearance around the fan and use anti-vibration screws or pads if available. Use motherboard ARGB software or a compatible controller to set color profiles and reduce LED brightness in low-light environments to minimize glare.
