Insert the tip of a spudger into the center hole punched into the side of the lower fan connector.
With the spudger still inserted, lift the lower fan connector straight up off the logic board.
The speaker cable connector attaches to the pins closest to the power supply. It is the only connector with four wires. The microphone cable attaches to the pins furthest away from the power supply and is the only connector with a dark orange wire.
