Figure 8. Removal steps of fan assembly and Heat Sink assembly (continued)
When installing: Before you attach the fan assembly to the computer, apply
thermal grease, at an amount of 0.2 grams, to the part shown in the figure
above. Either too much or too little grease application can cause a thermal
problem due to imperfect contact with a component.
