Installation—Digital Audio Models
Remove Fan Assembly
This section covers the removal of the fan assembly found on some
Digital Audio models.
If your machine does not have a fan assem-
bly covering the processor heat sink, skip to “Remove Heat Sink”
below.
1. Locate and carefully disconnect the 2-pin connector from the
processor card (Figure 18).
2. Unlatch the fan assembly’s clips from the processor card and
the heat sink, then lift the fan assembly out of the case and set it
aside
(Figure 19).
Remove Heat Sink
Locate the clips securing the processor heat sink to the processor card
(Figure 20); your heat sink may appear different from what is
pictured. Using caution to avoid touching the processor card and the
logic board, grasp one of the clips securing the heat sink with needle-
nose pliers, between the heat sink and processor card. Pull down
and away to unhook one side of the clip from the processor card
(Figure 20). Push the clip away from you to unhook it from the other
side. Repeat these steps with the other clip. Once the clips have been
unhooked, gently lift the heat sink and clips away from the processor
and set them aside, but not on the logic board.
Remove Processor Card
Remove the three screws securing the processor card to the logic
board
(Figure 21). Grasping its edges, gently lift one edge of the pro-
cessor card to separate it from the logic board, and then carefully lift it
straight up and away.
