• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as the electrical connectors in the processor socket.
• Remove and install only one PHM at a time. If the processor board supports multiple processors, install
the PHMs starting with the first processor socket.
• To ensure the best performance, check the manufacturing date on the new heat sink and make sure it
does not exceed 2 years. Otherwise, wipe off the existing thermal grease and apply the new grease onto it
for optimal thermal performance.
Notes:
• The heat sink, processor, and processor carrier for the system might be different from those shown in the
illustrations.
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
• See
https://serverproven.lenovo.com for a list of processors supported for your server. All processors on
the processor board must have the same speed, number of cores, and frequency.
• Before you install a new PHM or replacement processor, update your system firmware to the latest level.
See
“Update the firmware” on page 289.
The following illustration shows the components of the PHM.
