The Xigmatek Aqua V AIR comes with pre-installed ARGB fans. These fans can typically be controlled via:
- Motherboard Software: If your motherboard supports ARGB synchronization, connect the fan's ARGB cables to the motherboard's 3-pin 5V ARGB header and use the motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion) to customize lighting effects.
- Integrated Controller: If your case includes a built-in ARGB controller, use the dedicated button on the I/O panel to cycle through various lighting modes and colors.
6. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC components.
6.1 Dust Filter Cleaning
The Xigmatek Aqua V AIR case is equipped with dust filters to prevent dust buildup. Locate and gently remove the dust filters (typically on the top, front, and bottom). Clean them with compressed air or by rinsing with water. Ensure they are completely dry before reattaching.
