The fans are designed to interlock and daisy-chain, allowing power and ARGB signals to be transmitted between them with a single cable connection to the motherboard.

To connect fans:

- Gently slide the fans together until they click into place, ensuring a secure connection.
- Repeat for additional fans (up to 10 fans can be connected in a single chain).

3.2 Connecting to Motherboard
After chaining your fans, connect the single ARGB Header Cable from the last fan in the chain to your motherboard's 4-Pin PWM fan header and 3-Pin ARGB header. Refer to your motherboard manual for exact header locations.
4. Operating Your Fans
Once installed and connected, your AORUS EZ Chain Fans will operate based on your motherboard's fan control settings. For advanced ARGB lighting customization and fan speed control, utilize the GIGABYTE Control Center software (available for download from the official GIGABYTE website).
- ARGB Lighting: Synchronize fan lighting with other AORUS devices and customize effects through the GIGABYTE Control Center.
- Fan Speed Control: Adjust fan RPM (600-2000 RPM) via motherboard BIOS or GIGABYTE Control Center to balance cooling performance and noise levels.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your fans.
- Cleaning: Periodically clean fan blades and frames to remove dust buildup. Use a soft brush or compressed air. Ensure the PC is powered off and unplugged before cleaning.
- Inspection: Check cables for secure connections and signs of wear.
