Operating the Case Features
RGB Lighting Control
The L-shaped light strips and compatible RGB fans can be controlled using the Lian Li L-Connect 3 software. Download the latest version from the official Lian Li website. This software allows for customization of lighting effects, colors, and fan speeds.
Fan Speed Control
Fan speeds can be adjusted through the L-Connect 3 software to balance cooling performance and noise levels. Ensure all fans are properly connected to the fan controller or motherboard headers.
Maintenance
Cleaning
- Dust Filters: Regularly clean the removable dust filters located at the bottom and other intake areas to maintain optimal airflow and prevent dust buildup inside the case.
- Tempered Glass Panels: Use a microfiber cloth and a mild glass cleaner to clean the tempered glass panels. Avoid abrasive materials that could scratch the glass.
- Interior: Use compressed air to remove dust from internal components and fan blades. Ensure the system is powered off and unplugged before cleaning.
Troubleshooting
Fans Not Spinning/RGB Not Working
- Check all fan and RGB cable connections to the motherboard or dedicated controller.
- Ensure the fan controller (if used) is receiving adequate power, often via a SATA power adapter.
- Verify that the L-Connect 3 software is installed and updated to the latest version.
- Confirm that the USB 2.0 header connection from the controller to the motherboard is secure.
Tight Component Fit
- If a large GPU or radiator causes clearance issues, review the case's specifications for maximum component dimensions.
- Consider alternative mounting options, such as vertical GPU mounting (requires optional accessories).
