For access, remove these FRUs in order:

Attention: Do not handle the CPU thermal module roughly. Improper handling of the module can cause distortion or deformation and imperfect contact with components.

When installing:

• Before you attach the CPU thermal module to the computer, apply thermal grease, at an amount of 0.2 grams, on the part marked (a) as in the following figure. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component.
  
  
• Make sure that the fan connector is attached firmly.
