Remove a processor and heat sink
This task has instructions for removing an assembled processor and heat sink, known as a processor-heat-
sink module (PHM), a processor, and a heat sink. All of these tasks require a Torx T30 driver.

Attention:
• Intel Xeon SP Gen 2 processors are supported on the system board with part number 01PE842. If you use
the system board with part number 01GV277, update your system firmware to the latest level before
installing an Intel Xeon SP Gen 2 processor. Otherwise, the system cannot be powered on.
• Each processor socket must always contain a cover or a PHM. When removing or installing a PHM,
protect empty processor sockets with a cover.
• Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and
easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause
connection failures.
• Remove and install only one PHM at a time. If the system board supports multiple processors, install the
PHMs starting with the first processor socket.
• 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 electrical connectors in the processor socket. Do not remove the grease cover from
a heat sink until you are instructed to do so.
• 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.
Before removing a PHM:
Note: The heat sink, processor, and processor retainer for your system might be different than those shown
in the illustrations.
1. Remove the top cover. See “Remove the top cover” on page 56.
2. Remove the air baffle. See “Remove the air baffle” on page 60.
3. Remove any parts and disconnect any cables that might impede your access to the PHM.
To remove a PHM, complete the following steps:
