3.2 ARGB-beligtingsbeheer

If your case model includes ARGB fans, they are connected to a pre-installed ARGB controller and fan hub located behind the motherboard tray. The LED button on the top I/O panel allows you to cycle through various lighting modes. For advanced control, connect the 3-pin ARGB and PWM cables from the hub to your motherboard (if supported) to manage lighting and fan speeds via software.

4. Onderhoud

4.1 Skoonmaak van stoffilters

The front mesh panel can be easily removed by pulling it from the bottom, providing convenient access for cleaning the front fans and mesh. The top panel also features a magnetic dust filter for easy removal and cleaning. Regularly clean these filters to maintain optimal airflow and prevent dust buildup inside your system.

5. Probleemoplossing

5.1 Fans or ARGB Not Functioning

Ensure all fan and ARGB cables are securely connected to the pre-installed hub and that the hub itself is connected to SATA power and the appropriate headers on your motherboard (if using software control). Check your motherboard's BIOS/UEFI settings for fan control options.

5.2 Front Panel Not Sitting Flush

Inspect the front mesh panel for any physical damage or dents that might prevent it from sitting flush. Ensure all clips are intact and properly aligned when reattaching the panel.

5.3 Component Fit Issues

Refer to the specifications section for maximum component dimensions. If installing a large PSU, consider removing the hard drive cage to provide more clearance. For large CPU coolers, ensure RAM clearance is sufficient; some coolers allow for fan elevation to clear tall RAM modules.
