6. Remove the heat sink from the system processor module:
a. Loosen the heat sink actuation screw by turning the supplied hex key counterclockwise (A).
Loosen the screw until it moves freely. See the following figure.
b. Hold the heat sink (B) on opposing sides and remove the heat sink by lifting it upward. Set the
heat sink aside with the module side face up.
Note: If you plan to remove dust or debris from the heat sink, this operation must be completed in
another room that is greater than 7.6 m (24.9 ft) away from the work area.
