PowerLogix PowerForce 7447/7457 Installation Manual
Remove the heat sink retainer clips. The retainer clips are fairly strong springs. Press down firmly but carefully
with your finger on the center of the clip until the leg of the clip frees from the bottom of the processor card.
Pull the leg out until it slips over the edge of the processor card. This may require an additional tool, such as
a screwdriver to pry, or a pair of needlenose pliers. Remove both clips and remove the heat sink.
Note:
If you have certain Digital Audio or Quicksilver systems, you will have to remove a plastic fan shroud
and fan to expose the heatsink. Unplug the fan and remove the shroud, and set it aside.
Remove the screws that hold the Apple CPU card in place. Be careful not to lose the screws as you will
be reusing them to install the new PowerLogix processor upgrade card. If you have a Digital Audio or
Quicksilver system, you will have 4 screws to remove. You will only reuse 3.
