5. Setup and Installation

5.1. Prepare Your System

Before beginning installation, ensure your computer is completely powered down and disconnected from the power supply. Open your PC case to access the fan mounting locations.

5.2. Daisy-Chain Connection

The M25-140 Gen2 fans feature a unified frame design allowing them to be daisy-chained together. Align the connectors on the side of each fan and gently push them together until they click into place. This creates a single block of fans, simplifying installation and cable management.

5.3. Secure Fans

Mount the daisy-chained fan unit to your desired location (e.g., case front, top, or radiator) using the provided fan screws. Ensure the fans are securely fastened to prevent vibration. Once secured, attach the included screw covers for a clean, finished look.

5.4. Cable Connection (Linq6)

Connect the single Linq6 cable from the daisy-chained fan unit to a compatible fan/ARGB controller or motherboard header. This single cable manages both PWM fan speed control and D-RGB lighting. Refer to your motherboard or controller manual for specific connection points.

6. Operation

6.1. ARGB Lighting Control

Once connected, the D-RGB lighting can be controlled via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion 2.0, ASRock Polychrome Sync) or a compatible Phanteks D-RGB controller (e.g., NEXLINQ). Customize colors, effects, and brightness to match your system's aesthetic.

6.2. Fan Speed Control

The fan speed (PWM) is controlled through the same Linq6 cable. You can adjust fan curves and speeds via your motherboard's BIOS/UEFI settings or dedicated fan control software provided by your motherboard manufacturer. This allows for optimization between cooling performance and noise levels.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your fans.

• Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the system is powered off before cleaning.
• Inspection: Check cables for any signs of wear or damage. Ensure all connections remain secure.
• Do not use liquid cleaners directly on the fans or electrical components.
