AMD AM4/AM5 Installation
For AMD AM4 and AM5 motherboards, you will need to remove the motherboard's pre-installed plastic brackets but keep the original backplate. Install the four red standoffs onto the motherboard, then secure the two metal brackets with the provided screws. Ensure the brackets are firmly attached.

Intel LGA1700 Installation
For Intel LGA1700 motherboards, adjust the mounting hole position on the backplate to 1700. Install the backplate from the rear side of the motherboard. Then, install the four blue Intel 1700 plastic standoffs. Secure the brackets on the standoffs using the Intel screws, ensuring they pass through the LGA1700 holes on the brackets.
After securing the brackets for either AMD or Intel, apply thermal compound to the CPU's Integrated Heat Spreader (IHS). Remove the protective sticker from the heatsink base. Carefully place the heatsink onto the CPU, aligning the nuts on the heatsink with the screws on the installed brackets. Tighten both nuts evenly with a screwdriver until secure.

Connecting Cables
Connect the 4-pin PWM fan cable to the motherboard's 4-pin fan header to power and control the fan speed. Connect the ARGB lighting cable to the motherboard's 5V 3-pin ARGB header for lighting control. Finally, connect the USB cable to a USB 2.0 header on the motherboard and the display power connector to a SATA power cable from your power supply.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your CPU cooler.
- Dust Removal: Periodically clean the heatsink fins and fan blades to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Fan Inspection: Check the fan for any unusual noises or wobbling. Ensure the fan is securely mounted and its cables are not obstructing the blades.
- Thermal Compound: While not required frequently, consider reapplying thermal compound every few years or if you notice a significant increase in CPU temperatures.
Troubleshooting
If you encounter issues with your Thermalright Assassin Spirit 120 Vision ARGB White CPU Air Cooler, refer to the following common troubleshooting steps:
- No Power/Fan Spin: Ensure all power cables (4-pin PWM, SATA power for display) are securely connected to the motherboard and power supply. Check motherboard fan headers in BIOS.
- No ARGB Lighting: Verify the 5V 3-pin ARGB cable is correctly connected to the motherboard. Check your motherboard's ARGB software for control settings.
- LCD Screen Not Displaying: Ensure the USB 9-pin cable and SATA power cable for the display are properly connected. Confirm the TRCC software is installed and running.
- High CPU Temperatures: Check that the heatsink is securely mounted and making proper contact with the CPU. Verify thermal compound application. Ensure adequate airflow within your PC case.
- TRCC Software Issues: If the software is not functioning correctly, try reinstalling it from the official Thermalright website. Ensure your operating system is up to date.
