4. Operating Instructions
4.1 Power On/Off
Press the power button located on the top panel of the case to turn on your PC. To turn off, use the shutdown option in your operating system or press and hold the power button for a few seconds.
4.2 ARGB Fan Control
The EMPIRE GAMING Ruby case includes four 120mm Addressable RGB (ARGB) fans. These fans are connected to an integrated controller hub. You have two primary methods to control the RGB lighting:
- LED Button Control: Use the dedicated LED button on the top panel of the case to cycle through over 20 pre-set RGB effects and colors.
- Motherboard Synchronization (MB Sync): The integrated controller is compatible with popular motherboard RGB synchronization technologies via a 3-pin 5V ARGB header. Connect the controller to your motherboard's ARGB header to control lighting through software such as:
- ASUS Aura Sync
- GIGABYTE RGB Fusion
- MSI Mystic Light Sync
- ASRock Polychrome Sync

4.3 Airflow Configuration
The pre-installed fans are configured for optimal airflow, with front fans acting as intake and the rear fan as exhaust. This creates a positive pressure system, helping to keep dust out.

5. Maintenance
5.1 Dust Filter Cleaning
The EMPIRE GAMING Ruby case is equipped with dust filters to prevent dust buildup inside your system. Regularly clean these filters to maintain optimal airflow and cooling performance.
- Front Panel Filter: The mesh front panel acts as a dust filter. It can be carefully removed for cleaning.
- Top Panel Filter: A magnetic dust filter is located on the top panel. Simply lift it off for cleaning.
- PSU Filter: A removable dust filter is located at the bottom, beneath the power supply unit.
To clean, gently brush off accumulated dust or rinse with water if heavily soiled. Ensure filters are completely dry before reattaching.
