2. Installation Guide
Follow these steps to properly install your Mars Gaming MCA-WT ARGB Liquid Cooling Tube Case:
- Prepare Your System: Ensure your PC is powered off and disconnected from the main power supply before beginning installation.
- Identify Liquid Cooling Tubes: Locate the liquid cooling tubes on your AIO (All-In-One) cooler or custom loop. The MCA-WT is designed for tubes with a diameter of up to 12 mm and a length of 330 mm.
- Apply the Silicone Case: Gently stretch the eco-soft silicone tube case over your liquid cooling tubes. The flexible material allows for easy application and a snug fit. Ensure the entire length of the tube is covered as desired.
- Connect ARGB Cable: Locate the 5V 3-pin ARGB connector on the MCA-WT. Connect this cable to an available 5V 3-pin ARGB header on your motherboard or a compatible ARGB controller/hub.
Note: A 5V 3-pin ARGB header, controller, or hub is required to power and control the lighting effects. This product is not compatible with 12V 4-pin RGB headers.
- Secure Connections: Ensure all connections are firm and secure. Avoid excessive force when connecting the ARGB cable to prevent damage to the pins.
- Cable Management: Route the ARGB cable neatly to maintain good airflow and a clean aesthetic inside your PC case.

3. Operation
Once installed and connected, the ARGB lighting of the Mars Gaming MCA-WT can be controlled through your motherboard's ARGB software or a dedicated ARGB controller.
- Motherboard Software: If connected to a compatible motherboard (e.g., Asus Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion), use the respective software to customize lighting effects, colors, and patterns. Refer to your motherboard's manual for specific instructions on using its ARGB control software.
- ARGB Controller: If connected to an external ARGB controller, use the controller's buttons or software (if applicable) to adjust the lighting.
- Synchronization: The MCA-WT is designed to synchronize with other ARGB components connected to the same header or controller, allowing for a unified lighting theme across your PC.
4. Maintenance
To ensure the longevity and appearance of your Mars Gaming MCA-WT ARGB Liquid Cooling Tube Case, follow these simple maintenance guidelines:
- Cleaning: Gently wipe the silicone surface with a soft, dry, or slightly damp cloth to remove dust and grime.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the silicone material and the LED components.
- Inspection: Periodically inspect the silicone for any signs of wear or damage. Ensure the ARGB cable connection remains secure.
5. Troubleshooting
If you encounter issues with your Mars Gaming MCA-WT, refer to the following troubleshooting tips:
- No Lighting/Incorrect Colors:
- Check Connection: Ensure the 5V 3-pin ARGB connector is securely plugged into the correct header on your motherboard or controller.
- Verify Power: Confirm that your ARGB controller or motherboard's ARGB header is receiving power.
- Software Configuration: Open your motherboard's ARGB software (e.g., Asus Aura Sync) or controller software and ensure the ARGB device is detected and configured correctly. Try resetting the lighting profile.
- Compatibility: Confirm you are using a 5V 3-pin ARGB header, not a 12V 4-pin RGB header. Connecting to a 12V header can damage the LEDs.
- Poor Fit on Tubes:
- Tube Diameter: Ensure your liquid cooling tubes have a diameter of up to 12 mm. Tubes larger than this may not fit properly.
- Re-adjust: The silicone is flexible; try gently re-adjusting the case along the tube to achieve a better fit.
