What is the correct installation order for a processor to ensure proper cooling?

1. CPU, fan, thermal paste, heat sink

2. CPU, thermal paste, fan, heat sink

3. CPU, thermal paste, heat sink, fan

4. Thermal paste, heat sink, CPU, fan

The correct answer is: CPU, thermal paste, heat sink, fan

Ensuring proper cooling during the installation of a processor involves a specific sequence of steps that allows for optimal heat dissipation. The correct order begins with placing the CPU into the motherboard socket first. This is a crucial step as the CPU must be correctly seated in the socket to establish a proper electrical connection and for subsequent components to fit correctly around it. After the CPU is installed, applying thermal paste is essential. Thermal paste acts as an interface between the CPU and the heat sink, filling any microscopic gaps and enhancing thermal conductivity. This helps transfer heat away from the CPU more effectively. The application of thermal paste should be done after placing the CPU, as it is an essential layer that facilitates heat transfer once the heat sink is placed. The next step involves placing the heat sink on top of the CPU. The heat sink is designed to dissipate the heat generated by the CPU into the surrounding air. Properly positioning the heat sink over the thermal paste and CPU ensures that heat transfer occurs efficiently. Lastly, the fan, typically integrated into the heat sink assembly, is installed. The fan is responsible for moving air over the heat sink, further enhancing the cooling process by creating airflow that removes the heat. While the fan can be installed in tandem with the heat
