Procedure
Step 1. If you are replacing a processor and reusing the heat sink.
a. Remove the processor identification label from the heat sink and replace it with the new label
that comes with the replacement processor.
b. If there is any old thermal grease on the heat sink, wipe the thermal grease from the bottom of
the heat sink with an alcohol cleaning pad.
Step 2. If you are replacing a heat sink and reusing the processor.
a. Remove the processor identification label from the old heat sink and place it on the new heat
sink in the same location. The label is on the side of the heat sink closest to the triangular
alignment mark.
Note:
If you are unable to remove the label and place it on the new heat sink, or if the label is
damaged during transfer, write the processor serial number from the processor identification
label on the new heat sink in the same location as the label would be placed using a permanent
marker.
b. Install the processor into a new carrier.
Note:
Replacement heat sinks come with both gray and black processor carriers. Make sure
to use the carrier with the same color as the one you discarded earlier.
Figure 128. Installing a processor carrier
Make sure the handle on the carrier is in the closed position.
Align the processor on the new carrier so that the triangular marks align; then, insert the
marked end of the processor into the carrier.
Hold the inserted end of the processor in place; then, pivot the unmarked end of the
carrier down and away from the processor.
Press the processor and secure the unmarked end under the clip on the carrier.
