4.2 Instalazio Urrats Orokorrak
- Prepare your motherboard by removing any existing CPU cooler and cleaning the CPU surface thoroughly.
- Identify the correct mounting hardware for your CPU socket (Intel LGA115X/1200/1700/1851 or AMD AM4/AM5). Refer to the detailed mounting kit diagram below.
- Install the backplate (if required for your socket) and standoffs onto the motherboard.
- Apply a small amount of thermal paste to the center of the CPU's integrated heat spreader (IHS).
- Carefully place the heatsink onto the CPU, ensuring even contact.
- Secure the heatsink with the appropriate mounting brackets and screws, tightening them in an alternating pattern to ensure even pressure.
- Attach the two TL-K12 fans to the heatsink using the provided clips. Ensure the airflow direction is correct (typically blowing towards the rear of the case).
- Connect the 4-pin PWM fan connectors to the CPU_FAN headers on your motherboard. If using a Y-splitter, note that some motherboards may not detect individual fan speeds.
- Connect the 3-pin 5V ARGB connectors to the ARGB headers on your motherboard.
- Connect the LCD display's 9-pin USB 2.0 header cable to an available USB 2.0 header on your motherboard.
- Route all cables to avoid contact with fan blades and other moving parts inside the case.

5. Funtzionamendu-argibideak
5.1 Piztea eta hasierako abiaraztea
After successful installation, power on your computer. The fans should begin spinning, and the ARGB lighting should illuminate. The LCD screen will typically display a default animation or system information upon boot.
5.2 LCD Screen Functionality
The 5-inch LCD screen (480 x 854 resolution) on the top cover supports displaying system themes, logos, videos, and animated images. To customize the display, you will need to install the dedicated Thermalright software (usually available for download from the official Thermalright website). This software allows you to:
- Upload custom images and GIFs.
- Display real-time system information (CPU temperature, usage, etc.).
- Adjust screen brightness and orientation.

5.3 Haizagailuaren kontrola (PWM)
The TL-K12 fans are PWM (Pulse Width Modulation) controlled. Their speed will automatically adjust based on CPU temperature, as managed by your motherboard's BIOS/UEFI settings or dedicated fan control software. You can typically configure fan curves in your motherboard's BIOS to optimize for noise or cooling performance.
5.4 ARGB Argiztapen Kontrola
The ARGB lighting of the fans is controlled via the 3-pin 5V ARGB header connected to your motherboard. You can synchronize the lighting with other ARGB components in your system using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync).
6. Mantentzea
6.1 Cleaning the Heatsink and Fans
Regular cleaning helps maintain optimal cooling performance. It is recommended to clean the cooler every 6-12 months, or more frequently in dusty environments.
- Disconnect power from your computer.
- Carefully remove the fans from the heatsink.
- Use compressed air to blow dust out of the heatsink fins. Hold the can upright to prevent propellant discharge.
- Wipe fan blades and frames with a soft, dry cloth. Avoid using liquid cleaners directly on electronic components.
- Reattach the fans securely.
6.2 Thermal Paste Reapplication
Over time, thermal paste can dry out, reducing its effectiveness. If you notice a significant increase in CPU temperatures, consider reapplying thermal paste. This involves removing the heatsink, cleaning off old thermal paste from both the CPU and cooler base, and applying a fresh layer.
