4. Setup and Installation

The MC-3 Digital Memory Cooler offers dual installation methods to suit various scenarios. Please refer to the diagrams below for visual guidance.

4.1. Clip Installation (Snap-fit Memory Heat Sink)

This method is designed for quick and tool-free setup.

1. Align the clips on both sides of the memory cooler with your RAM sticks.
2. Gently press down until the clips securely fix the cooler to the RAM modules. No extra tools or skills are required.

4.2. Installation with Tablet Stand (Motherboard Mounting)

This method uses screws for a more secure attachment to the motherboard. It supports both M3 threaded holes and 6-32 UNC threaded holes.

1. Prepare the Cooler: Use a screwdriver to unscrew the existing screws and remove the snap-fit bracket from the memory cooler.
2. Attach Flat Bracket: Install the flat bracket (tablet stand) onto the memory cooler and secure it by tightening the screws.
3. Positioning: Position the heat sink to the designated location on your motherboard, typically above the RAM slots.
4. Secure with Screws (M3 Thread):
   • Slide a washer onto each support screw.
   • Install the support screws into the corresponding M3 threaded motherboard mounting holes.
   • Manually tighten the mounting screws by hand to secure the cooler.
5. Secure with Screws (6-32 UNC Thread - if applicable):
   • If your chassis standoffs are 6-32 threaded, use the provided adapter standoffs.
   • First, screw in the fixing screws, then install them into the motherboard standoff holes. Note that the height will increase by 7 mm with this method.

4.3. Wiring

Proper connection of the power and data cables is essential for functionality.

• Fan Power: Connect the fan power cable to the motherboard's CPU_FAN or a suitable 4-PIN PWM fan header.
• Data Communication: The digital display's data communication is provided by the motherboard's 9-pin USB port. Connect the cooler's data cable (USB) to an available 9-pin USB header on your motherboard.

5. Operating Instructions (Software)

The real-time data monitoring, ARGB lighting, and other functions of the digital display are controlled by the TRCC software.

1. Ensure Connection: Before installing the software, ensure the 9-pin USB cable is properly connected between the cooler and your motherboard.
2. Download Software: Download the latest TRCC software from the official Thermalright website: https://www.thermalright.com.cn/support/download/.
3. Installation: Unzip the downloaded file and double-click the installer to begin the installation process. Follow the on-screen prompts.
4. Run Software: After installation, double-click the "TRCC" shortcut icon on your desktop to run the software.
5. Automatic Startup: The software is designed to start automatically with your computer's operating system by default and will reside in the background of the taskbar for continuous monitoring. Do not force it to close or exit unless necessary.

6. Maintenance

To ensure optimal performance and longevity of your Thermalright MC-3 Digital Memory Cooler, follow these general maintenance guidelines:

• Regular Cleaning: Periodically clean the fans and heatsink fins to prevent dust buildup, which can impede airflow and cooling efficiency. Use compressed air or a soft brush.
• Cable Management: Ensure all cables are neatly routed and not obstructing airflow or fan operation.
• Software Updates: Keep the TRCC software updated to benefit from performance improvements and bug fixes.

7. Troubleshooting

• Digital Display Not Working / Showing '00':
  • Ensure the 9-pin USB data cable is securely connected to both the cooler and the motherboard.
  • Verify that the TRCC software is installed and running in the background.
  • If the display shows '00' on a DDR4 system, please note that the TRCC program might primarily display DDR5 temperatures via SPD HUB sensor detection. Temperature display functionality for DDR4 may be limited or unavailable.
• Unresponsive Software / Display Glitches:
  • In case of unknown or uncontrollable situations (e.g., software freeze, display errors), try unplugging and re-plugging the 9-pin USB cable from the motherboard to restart the digital display module.
  • Restart the TRCC software or your computer.
• Fans Not Spinning:
  • Check if the 4-PIN PWM fan power cable is correctly connected to a fan header on your motherboard.
  • Ensure the fan header is enabled and configured correctly in your motherboard's BIOS/UEFI settings.

8. User Tips

• The MC-3 Digital Memory Cooler is effective at maintaining memory temperatures, contributing to system stability.
• Always ensure the USB data cable is properly connected for the digital display and software functionality.
• For DDR4 users, be aware that the temperature display might not function as expected, potentially showing '00' degrees, as the TRCC program may be optimized for DDR5 SPD HUB sensor detection.

9. Warranty and Support

The Thermalright MC-3 Digital Memory Cooler comes with a 1-YEAR WARRANTY from the date of purchase. Please retain your proof of purchase for warranty claims.
