How do you connect a PC fan to a wall plug?

To connect a PC fan to a wall plug, first ensure the fan operates at the same voltage as the wall supply (typically 120V or 240V). If it’s a 12V fan, use a power adapter that converts the wall voltage to 12V. Connect the fan's positive and negative wires to the corresponding terminals on the adapter, then plug the adapter into a wall outlet. Always prioritize safety and ensure proper insulation to prevent electrical hazards.
