Logic Board
7. Apply approximately 0.3 to 0.5 cubic centimeter (cc) of T630 thermal gel (922-5929) to
the center of the center mating surface on the heatsink. (The 10 cc dispenser may be
graduated in milliliters. Note: A milliliter (ml) is the same as a cubic centimeter (cc)).
Note: To apply the thermal gel from the 10 cubic centimeter (cc) dispenser, remove
the end cap and push the plunger until the gel reaches the front opening. Note the
position of the end of the plunger in the tube. Dispense the gel until the plunger end
moves about 1/3 to 1/2 of 1 cc (ml). The plunger will move back slightly when
pressure is released, so push it slightly beyond the amount to be dispensed.
Note: After installing new thermal material, if you must briefly re-separate the logic board
from the heatsink, it is OK to retain the same, new material, as long as they are not
handled excessively.
