For access, remove this FRU in order:
- Do not handle the fan roughly. Improper handling of the fan can cause distortion or deformation and imperfect contact with components.
- Do not touch or apply any excessive force to the fan motor. It might cause damage to the fan assembly or the computer to mulfunction.
When installing: Make sure that the fan connector is attached firmly to the system board.
Note: Loosen the screws [2a] to [2f] in order, but do not remove them. When you attach the fan, secure the screws in order.

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 new CPU thermal device/fan, you need to peel the thin film off from the rubbers marked [b].
