3. Setup and Installation
3.1 Component Compatibility
The DS900 case supports a wide range of components. Please refer to the diagram below for maximum component dimensions and fan/radiator placements.

Figure 3.1: Internal layout indicating support for 360mm radiators, CPU coolers up to 170mm, GPUs up to 425mm, and various storage drives (2.5" SSD, 3.5" HDD).
3.2 Fan Installation and Airflow
The case comes with four 120mm ARGB fans pre-installed. Additional fans can be added for optimized airflow. The magnetic fan mounting system simplifies installation.

4. Operating Instructions
4.1 ARGB Lighting Synchronization
The G24 PC Fans support ARGB lighting synchronization with compatible motherboards. Connect the ARGB cables from the fans to your motherboard's 3-pin 5V ARGB header. Use your motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, ASRock Polychrome Sync) to customize lighting effects and colors.
4.2 Fan Speed Control (PWM)
The PWM (Pulse Width Modulation) fans allow for dynamic speed control based on system temperature. Connect the fan PWM cables to your motherboard's 4-pin fan headers. Fan speed can be managed through your motherboard's BIOS settings or dedicated fan control software.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your PC case and components.
- Dust Filter Cleaning: The DS900 features a magnetic top dust filter and other panel filters. Periodically remove and clean these filters to prevent dust buildup inside the case, which can impede airflow and component cooling. Use compressed air or a soft brush.
- Case Cleaning: Wipe down the exterior and tempered glass panels with a soft, lint-free cloth. For stubborn smudges on glass, a mild glass cleaner can be used, applied to the cloth first, not directly to the glass.
- Fan Cleaning: Gently clean fan blades with compressed air or a soft brush to remove dust. Ensure fans are not spinning during cleaning.
