NOTICE: To avoid damage, ensure that the processor aligns properly with the socket, and do not use excessive force when you install the processor.

5Set the processor lightly in the socket and ensure that the processor is positioned correctly.

6While lightly pressing down on the processor, rotate the release lever back toward the system board until it snaps into place, securing the processor.

7Clean the thermal grease from the bottom of the heat sink.

NOTICE: Ensure that you apply new thermal grease. New thermal grease is critical for ensuring adequate thermal bonding, which is a requirement for optimal processor operation.

8Apply the new thermal grease to the top of the processor.

NOTICE: Ensure that the floppy drive and audio cables are not routed so that they are pinched when the heat sink assembly is installed.

9Install the heat sink assembly:

a Place the heat sink and fan assembly back onto the heat-sink assembly bracket.

b Ensure that the two clamp grips are aligned with the two bracket projections.

c Hold the heat sink fan assembly in place and rotate the clamp lever

180 degrees clockwise to secure the heat sink and fan assembly.

NOTICE: Ensure that the heat sink assembly is correctly seated and secure.
