Removing a microprocessor and heat sink
Use this information to remove a microprocessor and heat sink.
About this task
Attention:
v Microprocessors are to be removed only by trained technicians.
v Be extremely careful, the pins on the socket are fragile. Any damage to the pins
may require replacing the system board.
v Do not allow the thermal grease on the microprocessor and heat sink to come in
contact with anything.
v Removing the heat sink from the microprocessor destroys the even distribution
of the thermal grease and requires replacing the thermal grease.
v 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.
v Use the microprocessor installation tool that came with the new microprocessor
to remove and install the microprocessor. Failure to use the microprocessor tool
may cause damage to the pins on the socket. Any damage to the pins may
require replacing the system board.
Note: Be sure to use the installation tool that comes with your microprocessor
installation tool assembly. The tools are similar in function and design, however
Tool A has one setting for installing one size of microprocessor, and supports the
following families of microprocessors: E5-26xx, E5-46xx. Installation Tool B has two
settings for installing two different sizes of microprocessors. The settings that are
marked on Tool B are “L” for smaller low core microprocessors, and “H” for larger
high core microprocessors. Installation Tool B supports the following families of
microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2.
Microprocessor Installation Tools A and B are shown in the following illustration.
