Install a processor-heat-sink module
The processor and heat sink are removed together as part of a processor-heat-sink-module (PHM) assembly. PHM installation requires a Torx T30 driver.
About this task
Read Installation Guidelines to ensure that you work safely.
Power off the server and disconnect all power cords for this task.
Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.
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.
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 system 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.
The heat sink, processor, and processor carrier for your 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 Server Proven (compatibility lookup) for a list of processors supported for your server. All processors on the system 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.
Installing an additional PHM can change memory requirements for the system. See Memory module installation rules and order for a list of processor-to-memory relationships.

- A video of this procedure is available at YouTube.
- Remove the processor socket cover, if one is installed on the processor socket, by placing your fingers in the half-circles at each end of the cover and lifting it from the system board.
- Install the processor-heat-sink module into the system board socket.Figure 2. Installing a PHM
Rotate the anti-tilt wire bails inward.
Align the triangular mark and four Torx T30 nuts on the PHM with the triangular mark and threaded posts of the processor socket; then, insert the PHM into the processor socket.
Rotate the anti-tilt wire bails outward until they engage with the hooks in the socket.
Fully tighten the Torx T30 nuts in the installation sequence shown on the heat-sink label. Tighten the screws until they stop; then, visually inspect to make sure that there is no gap between the screw shoulder beneath the heat sink and the processor socket. (For reference, the torque required for the fasteners to fully tighten is 1.1 newton-meters, 10 inch-pounds).
- If the processor comes with a T-shaped heat sink, fully tighten the two heat sink screws as shown. (For reference, the torque required for the fasteners to fully tighten is 1.1 newton-meters, 10 inch-pounds).Figure 3. Tightening T-shaped heat sink screws
