Operating Instructions
Fan Speed Control
The fan speed of your Dominator Platinum Airflow unit can be controlled through the Corsair Link software. This requires a Corsair Commander Pro (sold separately) connected to your system. Once connected, you can customize fan curves and monitor temperatures for optimal cooling performance.
RGB LED Customization
Personalize the LED colors of your cooling unit with 16.8 million values to match your system's theme or other Corsair RGB components. This customization is typically managed through Corsair's iCUE software (when connected to a compatible controller like the Commander Pro). The software allows for various lighting effects and synchronization.
Maintenance
To ensure the longevity and optimal performance of your cooling unit, periodic maintenance is recommended:
- Dust Removal: Regularly inspect the fan blades and heatsink fins for dust accumulation. Use compressed air to gently blow away dust. Avoid using harsh chemicals or abrasive materials.
- Cleaning: For stubborn dirt, a soft, dry cloth can be used to wipe down the exterior. Ensure the unit is powered off and disconnected before cleaning.
- Inspection: Periodically check all connections to ensure they are secure.
Troubleshooting
If you encounter issues with your Dominator Platinum Airflow unit, refer to the following common problems and solutions:
- Fan Not Spinning:
- Ensure the 4-pin power connector is securely plugged into a functional fan header on your motherboard or controller.
- Check your motherboard's BIOS/UEFI settings or fan control software to ensure the fan header is enabled and configured correctly.
- Test the fan on a different fan header if available.
- LEDs Not Lighting Up or Incorrect Colors:
- Verify that the RGB connector (if separate) is properly connected to a compatible RGB header or Corsair iCUE controller.
- Ensure Corsair iCUE software is installed and updated to the latest version.
- Check iCUE software settings to confirm the lighting effects are enabled and configured for the device.
- If using a motherboard's RGB header, ensure the motherboard's RGB software is installed and configured.
- Poor Cooling Performance:
- Ensure the fan is spinning at an appropriate speed. Adjust fan curves in Corsair Link/iCUE software if necessary.
- Clean any dust accumulation from the fan blades and heatsink fins.
- Verify that the unit is securely mounted and positioned correctly over the memory modules.
