Before we remove the fan we need to remove the cables for the wireless NIC card that go over the fan. They are the black and white cables shown in the red squares. To remove them grab them as close as you can to the placement of the red circles and then gently lift up. It will not take much to remove them from their terminals.
Once removed from their terminals trace the cables through the fan and set them over to the side so we can remove the fan in the next step.
