Setup and Installation
This section provides detailed instructions for installing your Thermalright Peerless Assassin 120 Digital White CPU Cooler. Please follow the steps carefully for proper installation and optimal performance.
Installation Video Guide

Step-by-Step Installation
1. Prepare the Motherboard
For Intel LGA1700/1851 motherboards: Adjust the backplate mounting hole position to 1700. Install the backplate from the back side of the motherboard. Place the blue LGA1700/1851 spacers onto the backplate from the front side. Install the metal brackets on these spacers using the Intel screws, ensuring the screws pass through the LGA1700/1851 holes on the brackets. Secure the metal brackets with four Intel screws.
For AMD AM5/AM4 motherboards: Remove the motherboard's plastic brackets. Keep the motherboard's original backplate. Install four pink AMD spacers onto the motherboard. Install two metal brackets on these spacers using the AMD screws. Secure the brackets with a screwdriver.

2. Apply Thermal Compound
Apply a small amount of thermal compound (included) onto the center of the CPU's Integrated Heat Spreader (IHS). A pea-sized dot is generally sufficient. This ensures optimal heat transfer between the CPU and the heatsink.
3. Prepare and Mount Heatsink
Before mounting, remove the magnetic top panel from the heatsink. Also, remove the protective sticker from the heatsink's copper base. Carefully place the heatsink onto the CPU, aligning the heatsink bracket nuts with the screws on the installed brackets. Tighten both nuts on the bracket with a screwdriver to apply mounting pressure evenly. Ensure the heatsink is firmly seated and does not wobble.

4. Install Fans
Install the fan clips onto the two 120mm fans. Attach the fans to the heatsink using the installed fan clips. Ensure the fans are oriented correctly for optimal airflow (typically blowing air through the heatsink fins towards the rear of the case).
5. Connect Cables
Connect each fan's 4-pin connector to the fan Y-cable to synchronize fan speed. Connect the fan Y-cable to the motherboard's CPU_FAN header. For ARGB models, connect the 3-pin ARGB headers to sync lighting effects. Connect the ARGB lighting cable to the motherboard's +5V ARGB header for lighting control. Finally, connect the USB cable to a USB 2.0 header on the motherboard to enable the digital display functionality and software control.
6. Reinstall Top Panel
Once all connections are made, reinstall the magnetic top panel back onto the heatsink.
Operating Instructions
The Thermalright Peerless Assassin 120 Digital White CPU Cooler operates automatically once installed and connected. The fans will adjust their speed based on CPU temperature, controlled by the motherboard's PWM signal.
To fully utilize the digital display's features, including color switching of temperature numbers and advanced monitoring, download and install the TRCC control software from the official Thermalright website. This software allows for customization and detailed data access.
Maintenance
- 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.
- Thermal Compound: Reapply thermal compound every 2-3 years, or if the cooler is removed and reinstalled, to ensure optimal heat transfer.
- Fan Inspection: Check fan blades for any damage or obstructions. Ensure fan cables are securely connected.
Troubleshooting
- No Fan Spin:
- Check if the fan Y-cable is securely connected to both fans and the motherboard's CPU_FAN header.
- Ensure the motherboard's CPU_FAN header is enabled in the BIOS/UEFI.
- High CPU Temperatures:
- Verify that the heatsink is properly mounted and making full contact with the CPU.
- Check if thermal compound was applied correctly and evenly.
- Ensure adequate airflow within the PC case.
- Clean any dust buildup on the heatsink fins and fan blades.
- Digital Display Not Working/Incorrect Readings:
- Ensure the USB cable is securely connected to the heatsink and a USB 2.0 header on the motherboard.
- Verify that the TRCC control software is installed and running.
- Check for any software updates for the TRCC application.
- ARGB Lighting Issues:
- Confirm the ARGB cable is correctly connected to the motherboard's +5V ARGB header.
- Check the motherboard's RGB control software for lighting settings.
