Setup and Installation
Follow these steps to install your COMMANDER CORE XT:
- Mounting the Unit: The COMMANDER CORE XT features embedded magnets for easy attachment to any flat metal surface inside your PC case. Alternatively, use the included adhesive strips for non-magnetic surfaces.
- Power Connection: Connect the SATA power cable from your power supply unit (PSU) to the COMMANDER CORE XT.
- USB Connection: Connect the USB 2.0 internal header cable from the COMMANDER CORE XT to an available USB 2.0 header on your motherboard. The unit also provides a USB 2.0 pass-through port for connecting an additional internal USB device.
- Fan Connections: Connect up to six 4-pin PWM fans to the 'FANS' headers (1-6) on the COMMANDER CORE XT.
- RGB Connections: Connect your CORSAIR RGB fans to the 'RGB HUB' headers (1-6). For other CORSAIR RGB devices (e.g., Hydro X Series lighting, RGB LED Lighting PRO Expansion Kit light strips), use the dedicated 3-pin RGB header. The COMMANDER CORE XT intelligently detects connected CORSAIR RGB fans. Note: CORSAIR SP RGB Series fans are not supported.
- Temperature Sensors: Connect the two included repositionable temperature sensors to the 'TEMP 1' and 'TEMP 2' ports. Place these sensors strategically within your system to monitor temperatures accurately.
- Software Installation: Download and install the latest CORSAIR iCUE software from the official CORSAIR website. This software is essential for configuring and controlling your COMMANDER CORE XT.

Operating Instructions
The CORSAIR iCUE software is the central interface for managing your COMMANDER CORE XT. Once installed and your device is connected, launch iCUE to access its features.
Fan Control
The COMMANDER CORE XT allows for precise control over up to six PWM fans. Within iCUE, you can:
- Adjust individual fan speeds.
- Set custom fan curves based on system temperatures.
- Enable Zero RPM mode to stop fans completely at low loads for silent operation.

RGB Lighting Control
Control up to 264 RGB LEDs across various CORSAIR RGB devices. The iCUE software provides extensive customization options:
- Choose from a wide array of lighting effects and colors.
- Synchronize lighting across all compatible CORSAIR RGB components.
- Create custom lighting profiles that can react to system temperatures or other parameters.

Maintenance
The CORSAIR iCUE COMMANDER CORE XT requires minimal maintenance. Ensure the unit is kept free from dust and debris to maintain optimal performance. Periodically check cable connections to ensure they are secure. No user-serviceable parts are inside the unit.
Troubleshooting
Fans or RGB not responding in iCUE:
- Ensure the COMMANDER CORE XT is properly connected to your PSU via SATA power and to your motherboard via the USB 2.0 header.
- Verify that all fans and RGB components are securely plugged into the correct headers on the COMMANDER CORE XT.
- Restart the CORSAIR iCUE software. If the issue persists, try restarting your computer.
- Ensure you have the latest version of CORSAIR iCUE software installed.
- Check for any conflicting software that might interfere with iCUE's control over hardware.
- Confirm that your fans are compatible CORSAIR RGB fans (SP RGB Series fans are not supported by the COMMANDER CORE XT).
iCUE software crashes or freezes:
- Ensure your operating system and drivers are up to date.
- Try performing a clean reinstallation of the iCUE software.
- If other CORSAIR devices are connected, ensure their firmware is updated.
Temperature readings are inaccurate or missing:
- Ensure the temperature sensors are securely plugged into the 'TEMP' ports on the COMMANDER CORE XT.
- Verify the sensors are placed in locations where they can accurately measure temperatures without being obstructed or directly touching hot components.
