CAUTION: The microprocessor and heat sink can become extremely hot. Be sure
they have had sufficient time to cool before handling.
NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the
microprocessor. The heat sink is necessary to maintain proper thermal conditions.
NOTICE: After removing the heat sink, place it upside down on a flat surface to prevent the
thermal interface material from being damaged or contaminated.

NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending
the pins can permanently damage the microprocessor.
Lift the microprocessor out of the socket and leave the release lever in the open
6
position so that the socket is ready for the new microprocessor.
NOTICE: Be careful not to bend any of the pins when unpacking the microprocessor. Bending
the pins can permanently damage the microprocessor.
Unpack the new microprocessor.

NOTE: If a cooling fan is mounted on the heat sink, you can remove the heat sink without
removing the fan. However, you can remove the fan to provide easier access to the heat-sink
retention clip(s). For information on removing a cooling fan, see your Installation and
Troubleshooting Guide.
Remove the retention clip(s) securing the heat sink to the microprocessor by
pressing down firmly on the retention clip tab, and then removing the clip from
the heat sink.
See your system information label on the system cover for heat-sink retention clip
information.
Remove the heat sink. See your Installation and Troubleshooting Guide for
information on removing the heat sink.
