MacBook (13-inch) Take Apart — Heatsink 80
Use an alcohol wipe to completely clean the two pads on the heatsink.
Caution: The syringe steps for this procedure are required only when the heatsink and
logic board are removed to replace a later part (such as the bottom case) and when no
new heatsink with pre-applied thermal grease will be installed. Refer to the heatsink
conditions in step 1 for details before attempting to replace the thermal grease.
Note the contents of the syringe of thermal grease.
Important: One syringe (922-7144) contains 0.3 to 0.35 cubic centimeters (cc) of thermal
grease. That is enough for 0.1 to 0.12 cc of grease per chip for up to three chips. Because this
computer has only two chips, the last 1/3 of thermal grease remains in the syringe. Use one-
third of the syringe contents per chip. Using a felt-tip pen, mark the 1/3 points on the syringe
before applying the rst dab.
