Troubleshooting Common Issues
- Temperature Display Not Working: Ensure the Antec iUnity software is correctly installed and running. Check the connection cable from the case's I/O panel to your motherboard.
- Fan Noise/Performance: Verify that all PWM fans are properly connected to your motherboard's fan headers. Adjust fan curves in your motherboard's BIOS/UEFI or through fan control software for optimal balance between cooling and noise. Ensure dust filters are clean.
- Cable Management Difficulties: Utilize the included velcro straps and cable covers to organize cables. The 30mm clearance behind the motherboard tray provides ample space for routing.
