When installing:

  • Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams, on the parts marked [a] as in the following figures. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component. For the fan in the integrated graphics models, you need to peel the thin film off from the thermal rubber marked [b].

For Discrete graphics models:
