7.
If using a new fan sink, remove the protective covering from the bottom of the fan sink and place
it in position atop the processor.
8.
Secure the fan sink to the system board and system board tray with the 4 captive screws and
attach the fan sink control cable to the system board.
CAUTION:
Heat sink retaining screws should be tightened in diagonally opposite pairs (as in
an X) to evenly seat the heat sink on the processor. This is especially important as the pins on
the socket are very fragile and any damage to them may require replacing the system board.
NOTE:
After installing a new processor onto the system board, always update the system
ROM to ensure that the latest version of the BIOS is being used on the computer. The latest
system ROM BIOS can be found on the Web at:
