Thermal Pad Replacement Instructions

The following instructions explain how to replace the thermal pads in the iMac (Flat Panel) computer. These

pads must be changed each time the main logic board is removed from the bottom housing.

No tools

are required for this procedure

Procedure

1. Remove the old thermal pads (circled below) from the bottom housing. Note: If you don’t see all three

thermal pads on the bottom housing, check the bottom side of the logic board.

2. Using the thermal pad kit, remove the clear protective backing from the new thermal pads.

3. Place the new thermal pads in the bottom housing. Note: Avoid unnecessary contact with either side of

the thermal pad as dirt and body oils reduce the thermal pad's conductivity.

4. Press down on the blue protective backing to make sure each thermal pad has even contact with the

bottom housing. There should be no air pockets.

5. Remove the blue protective backing from the new thermal pads.

6. Replace the logic board. Warning: Replace the thermal pads. Refer to “Thermal Pad Replacement

Instructions” mentioned earlier in this chapter.
