Figure 45. Installing the heat sink
12. Secure the heat sink:
a. Upon placing the heat sink on the microprocessor, ensure that the heat-sink load arm on the side
of the heat sink becomes engaged, as shown in Figure 46 on page 82.
b. While holding the heat sink in place, use the supplied nut driver to tighten the heat-sink
actuation screw. Turn the screw clockwise a few turns.
c. Is the load arm still engaged?
Yes:
Continue turning the actuation screw clockwise until a firm stop is reached.
No:
Unscrew the actuation screw. Hold the load arm onto the heat sink while tightening the
screw until a firm stop is reached.
Note: If during this step, the heat sink moves noticeably, it is likely that the load arm is not
engaged. If the heat sink moves noticeably, unscrew the actuation screw and hold the load arm
onto the heat sink while tightening the screw until a firm stop is reached.
