3-18 Disassembly and Reassembly
Processor and Heat Sink Removal
The Pentium III processor is installed in a Slot370 socket. The processor is
cooled by a heat sink attached to the top of the processor and the CPU fan.
Remove the heat sink and processor as follows.
If the system was just running, the processor and heat sink
on the system board are hot. To avoid a burn, let the
components cool for 10 minutes before continuing.
Before handling components, reduce static discharge by
touching a metal part on the chassis.
1.
Remove the system board and support plate assembly (see “System Board
and Support Plate Assembly Removal” earlier in this section). It is not
necessary to remove the support plate.
2.
Position the system board with the processor side facing up and the support
plate facing down.
3.
Remove the two screws holding the CPU fan to the processor heat sink (see
the following figure). Move the fan aside.
It is not necessary to unplug the fan from its connector unless replacing the
fan (if replacing, see “CPU Fan Removal” earlier in this section).
4. Remove the retention clip from the heat sink and processor as follows (see
the following figure).
!
Simultaneously press down on the left end of the retention clip while
carefully pulling out the left end to unhook it from the processor socket
tab.
!
Remove the retention clip from the tab on the other end of the processor
socket. Set the clip aside.
