Install a T-shaped heat sink

Use this information to install a T-shaped heat sink.
About this task
Attention:
• 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.
Before installing the heat sink:
• If you use the existing heat sink:
1. Remove the thermal grease on the heat sink by using an alcohol cleaning pad.
2. Apply new thermal grease (TaiSol TC5288) in a quadrilateral design on the top of the processor.
Note: Do not apply too much thermal grease. Too much thermal grease can result in excess grease
coming in contact with and contaminating the processor socket.
Figure 94. Applying thermal grease
• If you use a new heat sink, the thermal grease is pre-applied to the heat sink. Remove the protective cover
and install the heat sink.
