4. Setup & Installation
4.1. Pre-Installation Checklist
- Compatible Motherboard: Ensure your motherboard has an LGA1200 socket and uses an Intel 500 series or select 400 series chipset. Refer to your motherboard's documentation for specific compatibility.
- Tools: You may need a Phillips head screwdriver.
- Thermal Paste: The included thermal solution typically has pre-applied thermal paste. If using an aftermarket cooler, ensure you have thermal paste.
- Discrete Graphics Card: This processor requires a discrete graphics card for display output.
4.2. Processor Installation
- Prepare the Motherboard: Open the CPU socket retention lever on your motherboard. Lift the load plate.
- Align the Processor: Carefully remove the processor from its packaging. Locate the alignment notches on the processor and the socket. The gold triangle on the processor should align with the triangle on the socket.
- Insert the Processor: Gently place the processor into the socket. Do not force it. If it does not seat easily, re-check the alignment.
- Secure the Processor: Close the load plate and then push down the retention lever until it locks into place.

4.3. Thermal Solution (CPU Cooler) Installation
The Intel® Laminar RM1 thermal solution is designed for easy installation.
- Prepare the Cooler: The included cooler typically has pre-applied thermal paste on its base. If not, apply a thin, even layer of high-quality thermal paste to the center of the processor's IHS.
- Position the Cooler: Align the four mounting pins on the cooler with the corresponding holes around the CPU socket on the motherboard.
- Secure the Cooler: Press down firmly on each corner of the cooler until all four pins click into place. Ensure the cooler is securely attached and does not wobble.
- Connect Fan Power: Connect the cooler's 4-pin power cable to the CPU_FAN header on your motherboard.
