Step 1 Mac mini (PowerPC) Fan Replacement

• You can skip this step if you bought your . Putty knives purchased from iFixit come with pre-ground edges.
• You'll need a putty knife in order to open the case. A 1.5 inch thin putty knife will work well, but you'll want to grind the edge down. Rub the putty knife's short edge back and forth on a sheet of all purpose rough grit sandpaper (100 grit will work fine) until it attains a beveled edge.

Step 2

• Place the mini upside down on a cloth and turn it so that the apple leaf faces you.
• Insert the putty knife into the seam between silver outer case and the white plastic. If you have trouble, you can insert the putty knife at an angle or grind the knife's edge down further. Push the blade down until you meet firm resistance (roughly 3/8 of an inch).

• Pull directly back on the putty knife until the white plastics pops up. Don't worry about bending the putty knife too far or breaking the plastic tabs. Just continue to pull back on the putty knife until the case pops free.
• Repeat this procedure on the other side.

Step 9
• If your mini has neither an Airport card nor a Bluetooth board, you can simply lift the optical drive up and away. Otherwise, you need to disconnect the Airport and/or Bluetooth antenna cables first.
• With your free hand, pull the Bluetooth cable up from Bluetooth board and unplug the Airport antenna cable from the right of the Airport card. Caution: both of these connections are very small. When re-assembling unit after repair, you may want to remove the two screws holding the airport card to the assembly and lift the card up and out to re-attach the cables.

Step 10
• Flip the mass storage assembly over so that the fan faces up.
• Remove the three long, black Phillips screws from the corners of the fan. These screws are strongly threaded, and will offer significant resistance.
• There is no screw in the bottom left corner.

Step 12
• The cable you're about to remove is very fragile - do not pull directly on the wires. Instead, try to pry up the connector directly, using your fingernails or a small flathead screwdriver if necessary.
• Disconnect the fan connector from the interface board.
