Troubleshooting
Here are some common issues and their potential solutions:
| Issue | Possible Cause | Solution |
|---|---|---|
| Poor Airflow/High Temperatures | Dust buildup on filters/fans, improper fan orientation, poor cable management. | Clean dust filters and fans. Ensure fans are oriented correctly (intake/exhaust). Improve cable management to reduce airflow obstruction. |
| Side Panel Not Closing Properly | Cables obstructing the panel, components not fully seated. | Reroute cables to ensure they are not interfering with the panel. Double-check that all components are fully seated and secured. |
| Front I/O Ports Not Functioning | Cables disconnected from motherboard, incorrect motherboard header connection. | Verify that all front I/O cables (USB, audio, power switch) are securely connected to the correct headers on your motherboard. Refer to your motherboard manual. |
| GPU Not Fitting Vertically | GPU length exceeds maximum supported, riser cable not installed correctly. | Confirm GPU length is within 361.5mm. Ensure the PCIe riser cable is properly seated and secured at both ends. |
