Configuració i instal·lació
This section guides you through the installation process. Ensure your system is powered off and unplugged before beginning. Refer to your motherboard manual for specific instructions on CPU cooler installation points.
Compatibilitat
The Assassin X 120R Digital Black CPU Cooler is compatible with the following CPU sockets:
- Intel: LGA 1851, LGA 1700, LGA 1150, LGA 1151, LGA 1155, LGA 1156, LGA 1200
- AMD: AM4, AM5
Note: For AMD platform installation, the original motherboard backplate is required.
Passos generals d'instal·lació
- Prepareu la placa base: Identify the correct mounting brackets for your CPU socket (Intel or AMD). Remove any existing CPU cooler and clean the CPU surface of old thermal paste using isopropyl alcohol.
- Aplicar pasta tèrmica: Apply a small amount of thermal paste (included) to the center of the CPU's integrated heat spreader (IHS). A pea-sized dot is usually sufficient.
- Instal·leu el maquinari de muntatge: Attach the appropriate backplate (if required for Intel) and standoffs to the motherboard. Secure the mounting arms to the standoffs.
- Col·locació del refrigerador: Carefully place the heatsink onto the CPU, aligning the mounting holes on the cooler with the mounting arms.
- Assegureu la nevera: Use the provided screws to secure the heatsink to the mounting arms. Tighten screws in a diagonal pattern until snug, but do not overtighten.
- Connect Fan and Digital Display Cables:
- Connecteu el cable del ventilador PWM de 4 pins al capçalera CPU_FAN de la placa base.
- Connect the digital display cable to an available USB 2.0 header on your motherboard.

Instruccions de funcionament
The Assassin X 120R Digital Black features a digital display and a PWM controlled fan for optimal performance.
Digital Display Functionality
The integrated digital screen provides real-time monitoring of critical system parameters. With the TRCC software, you can customize the display to show:
- Temperatura de la CPU
- Ús de la CPU
- Graphics Card Temperature
- Graphics Card Utilization
This allows for easy access to system information at a glance. The display's color can also be adjusted via the TRCC software, potentially changing based on temperature or usage.

PWM Fan Control
The 120mm PWM fan automatically adjusts its speed (up to 2000 RPM) based on the CPU temperature, as controlled by your motherboard's fan headers. This ensures optimal cooling performance while minimizing noise levels. No manual adjustment is typically required for fan speed.
Manteniment
Un manteniment regular ajuda a garantir la longevitat i el rendiment òptim del refrigerador de la CPU.
- Neteja de pols: Periodically (e.g., every 3-6 months), power off your computer and use compressed air to remove dust accumulation from the heatsink fins and fan blades. Hold the fan blades gently to prevent over-spinning during cleaning.
- Inspecció del ventilador: Check the fan for any signs of wear, damage, or unusual noise. Ensure the fan cable is securely connected.
- Pasta tèrmica: While not frequently required, if you remove the cooler or notice significantly higher temperatures over time, consider reapplying fresh thermal paste.
Resolució de problemes
If you encounter issues with your CPU cooler, refer to the following common troubleshooting steps:
- El ventilador no gira:
- Ensure the 4-pin PWM fan cable is securely connected to the CPU_FAN header on the motherboard.
- Check BIOS/UEFI settings to ensure the CPU fan control is enabled and configured correctly.
- Temperatures altes de la CPU:
- Verify that the cooler is properly seated on the CPU and that mounting screws are tightened evenly.
- Confirm that thermal paste was applied correctly and is making good contact.
- Clean any dust accumulation from the heatsink fins and fan.
- Assegureu-vos que hi hagi un flux d'aire adequat dins de la carcassa del vostre PC.
- Digital Display Not Working/Incorrect Readings:
- Check if the USB 2.0 header cable for the display is securely connected to both the cooler and the motherboard.
- Install or update the TRCC software from the Thermalright official weblloc.
- Ensure the TRCC software is running in the background.
