Press the power button located on the top I/O panel to turn on your PC. To shut down, use the operating system's shutdown function. For a forced shutdown, press and hold the power button for several seconds.
5.2 ARGB Lighting Control
The pre-installed ARGB fans are connected to an ARGB hub. You can control the lighting effects using the dedicated LED button on the top I/O panel to cycle through various modes. For motherboard synchronization, ensure the ARGB hub is connected to a compatible 3-pin 5V ARGB header on your motherboard and use your motherboard's RGB software.
6. Maintenance
6.1 Cleaning Dust Filters
The SAMA 3509 case includes magnetic dust filters on the top and a PVC dust filter at the bottom. Regularly remove and clean these filters to maintain optimal airflow and prevent dust buildup inside the case. Simply slide them out, clean with water or a soft brush, and re-install once dry.
6.2 General Cleaning
Use a soft, dry cloth to wipe down the exterior of the case. For the tempered glass panel, use a glass cleaner and a microfiber cloth. Avoid abrasive cleaners or solvents that may damage the finish.
7. Troubleshooting
- PC not powering on: Check all power connections, including the 24-pin ATX, 8-pin CPU, and GPU power cables. Ensure the PSU switch is in the 'ON' position. Verify front panel power button connection to the motherboard.
- Fans not spinning or RGB not working: Check fan connections to the ARGB hub and the hub's connection to the PSU (SATA power) and motherboard (ARGB header). Ensure the LED button cable is correctly connected.
- Overheating: Ensure proper fan orientation for airflow. Clean dust filters regularly. Verify CPU cooler and GPU cooler are properly seated and functioning.
- No display: Ensure the monitor cable is connected to the graphics card (not the motherboard I/O if a dedicated GPU is installed). Reseat the graphics card and RAM modules.
