CAUTION: To avoid damage to CPU socket pins and ensure proper system cooling, install
a CPU baffle in an empty CPU socket.

heatsink module” (page 39) for more information on the installation procedure.
IMPORTANT:

cause analysis.
• Do not discard your heatsink packaging or processor ESD bag. Reuse this packaging to return
any exchange material.

• To receive credit for returning defective material, make sure to include the processor paperwork
NOTE: After replacing the processor and heatsink module use the cpuconfig from UEFI to
verify the that the processor socket has been reconfigured.
