Step 2. Remove the processor heat sink.
Attention:
• Avoid touching the processor socket or processor contacts. Processor-socket contacts are very
fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin,
can cause connection failures.
• Prevent the thermal grease on the processor or heat sink from coming in contact with anything.
Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal
grease can damage components, such as the electrical connectors in the processor socket.
a.
Use a Phillips screwdriver to fully loosen the captive screws from the heat sink in the
removal sequence shown on the heat-sink label as well as indicated in the illustration below.
b.
Lift the heat sink up evenly to remove it from the node.
Important: To prevent damage to the processor, make sure to follow the loosening sequence
indicated in the illustration.
