c. Carefully position heatsink over the CPU, and align the heatsink screws with
the screw holes in the motherboard.
Caution –
Possible component damage caused by heat. Avoid moving the heatsink
after it has contacted the top of the CPU. Too much movement could disturb the
layer of thermal compound, leading to ineffective heat dissipation and component
damage.
d. Lower the heatsink onto the CPU.
e. Gently press down on the top of the heatsink to counteract the pressure of
the captive spring-loaded screws, and use a #2 screwdriver to alternately
tighten the each screw, 180 degrees at a time, until tight (see
FIGURE 3-14
).
Note – After replacing the CPU, you must update the BIOS and firmware, as
described in Chapter 5 , Updating ELOM Firmware .
