      Fan assembly removal and installation

      For access, remove these FRUs in order:

      Attention:

      • 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.

      Please perform the following step as shown in the picture below:

      Note:

      Loosen the screws [2a] to [2f] in order, but do not remove them. When you attach the fan, secure the screws in order.

      Removal steps of fan assembly (continued)

       

      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].
