To install the heat sink: 1. Put the heat sink frame on the processor socket. 2. Properly align the heat sink spring-loaded screws to the system board mounting holes. 3. Tighten the spring-loaded screws clockwise to secure the heat sink connection to the system board. CAUTION: To prevent overheating or a possible system crash, use only a heat sink model specified for the HP ProLiant server. CAUTION: To prevent the heat sink from tilting to one side during installation and removal procedures, only tighten the first screw three quarter. Tighten the second screw fully, and then go back and tighten the first screw fully. Do not over tighten the heat sink's spring-loaded screws to prevent them from breaking off. A maximum torque of 4 in-Ib is set for the system.
