Step 5 Before installing a CPU or heat sink, use tissue to clean up the oil, remaining thermal
compound, or foreign objects on their surfaces.
Step 6 Determine the area on the CPU for contacting the heat sink, and paste 0.4 ml of thermal
compound on the area.
NOTE
The thermal compound injector has volume marks.
You can paste thermal compound using any of the six methods shown in Figure 7-73 Dual-
line, five-point, and S-shape, and cross pasting methods are recommended.

Step 7 Use a clean card to smear the thermal compound over the entire center of the CPU.
The thermal compound layer is as thick as a common piece of paper. Figure 7-74 shows the
smeared thermal grease layer. Ensure that the thermal compound is evenly and fully painted.
