11Install the heat sink.

NOTE: Your kit may contain a replacement heat sink if you are installing a processor that consumes additional power. The new heat sink may not appear different than the original one; however, it has improved thermal dissipation specifications and must be used.

aUsing a clean lint-free cloth, remove the thermal grease from the heat sink.

CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.

bOpen the grease applicator included with your processor kit and apply all of the thermal grease in the applicator to the center of the topside of the new processor.

cPlace the heat sink on the processor. See Figure 3-12.

dClose the heat-sink release levers. See Figure 3-12.

12Replace the cooling shroud. See "Installing the Cooling Shroud" on page 88.

13Close the system. See "Closing the System" on page 86.

14Reconnect your system and peripherals to their electrical outlets, and turn on the system.

15Press <F2> to enter the System Setup program, and check that the processor information matches the new system configuration. See "Entering the System Setup Program" on page 58.

16Run the system diagnostics to verify that the new processor operates correctly.

17See "Running the System Diagnostics" on page 181 for information about running the diagnostics.
