PHANTEKS 140mm M25 Gen2 PWM D-RGB case fan, white

PHANTEKS 140mm M25 Gen2 PWM D-RGB case fan in white is a chassis cooling fan designed for standard ATX, Micro-ATX and Mini-ITX builds that require a balance of airflow, acoustic control and addressable RGB lighting. The fan uses PWM control for dynamic speed adjustment and features D-RGB (addressable RGB) lighting for synchronized effects when connected to compatible RGB controllers or motherboard headers. The white finish provides a clean aesthetic that integrates with light-themed builds or contrasts with darker components.

Advantages

The M25 Gen2 combines PWM speed control with a 140mm blade design to deliver substantial airflow while allowing automatic or manual reductions in RPM to lower noise. Its D-RGB lighting enables per-LED lighting effects and synchronization with common motherboard lighting software when connected to a 3-pin 5V addressable header. The white frame and blades reduce visual distraction and help diffuse colored lighting for a uniform appearance. Bearings and motor design focus on operational longevity and stable rotation under varying loads.

Suitable for

• Case intake or exhaust in mid-tower and full-tower PC cases
• Building systems that require 140mm fan support for quiet airflow
• RGB-coordinated builds using 3-pin 5V addressable RGB headers or compatible controllers
• Upgrading stock fans to improve cooling or reduce noise

Key specifications

• Fan size: 140 mm frame diameter
• Control type: PWM (pulse-width modulation) for automatic speed regulation
• Lighting: D-RGB (addressable RGB) compatible with 3-pin 5V headers
• Color: white frame and blades
• Mounting: standard 140mm screw hole pattern for chassis installation

How to use

Install the fan into a compatible 140mm mounting location in your PC chassis using the standard screws supplied with your case or fan. Connect the 4-pin PWM power cable to a motherboard fan header or fan controller to allow automatic speed control based on system temperatures. Connect the 3-pin 5V addressable RGB cable to a compatible RGB header or controller to enable lighting effects; ensure the header voltage and pinout match the D-RGB connector to avoid damage. Position the fan for intake or exhaust according to your case airflow plan, ensuring unobstructed airflow paths and adequate clearance from cables and components.

Usage recommendations

For optimal results, use motherboard fan control profiles to balance noise and cooling, and synchronize D-RGB lighting through supported software. Clean the fan blades periodically to maintain airflow efficiency. Verify the 5V addressable RGB header compatibility before connecting the lighting cable.
