Removing a microprocessor and heat sink
Use this information to remove a microprocessor and heat sink.
The following notes describe the type of microprocessor that the server supports and other information that
you must consider when you install a microprocessor and heat sink:
• The server supports one Intel land grid array (LGA) 1150 dual-core or quad-core microprocessor. The
type, speed, and L3 cache of the microprocessor depends on the server model.
• Read the documentation that comes with the microprocessor to determine whether you have
to update the server firmware. To download the most current level of server firmware, go to
http://www.lenovo.com/support and http://www.ibm.com/support/ fixcentral.
• The microprocessor uses an integrated voltage regulator on the system board.
Attention:
• Microprocessors are to be installed only by trained technicians.
Important:
Always use the microprocessor installation tool to install a microprocessor. Failing to use
the microprocessor installation tool may damage the microprocessor sockets on the system board. Any
damage to the microprocessor sockets may require replacing the system board.
• 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.
