Note: Removing the heat sink from the microprocessor destroys the even distribution of the thermal
grease and requires reapplying the thermal grease.
Attention:
• Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything.
Contact with any surface can compromise the thermal grease and the microprocessor socket.
• Dropping the microprocessor during installation or removal can damage the contacts.
• The microprocessor contacts are fragile. Do not touch the microprocessor contacts; handle the
microprocessor by the edges only. Contaminants on the microprocessor contacts, such as oil from your
skin, can cause connection failures between the contacts and the socket.
• The pins on the sockets are fragile. Any damage to the pins might require replacing the system board.
• When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For
details about handling these devices, see “Handling static-sensitive devices” on page 88.
• The microprocessor fits only one way on the socket.
• Removing the heat sink from the microprocessor destroys the even distribution of the thermal grease,
you must wipe off the thermal grease with the alcohol wipes and reapply clean thermal grease. See
“Thermal grease” on page 150.
To install the microprocessor and heat sink, do the following:
Step 1. Install the microprocessor.
a. Align the microprocessor with the socket (note the alignment marks 1 and the position of the
notches) and carefully place the microprocessor on the socket.
b. Close the microprocessor bracket frame.
c. Close the microprocessor retention latch by securing the handle back to its position.
