6. Inspect the thermal interface material (TIM) for visible signs of damage, as shown in Figure 168 on
page 148 or Figure 169 on page 148. If you see folds, tears, bends, or if you have doubts about the
TIM, replace it.
The system can use two types of thermal interface materials (TIMs).
v One TIM is silver-colored with trimmed corners and a red line, part number 44V8038.
The silver-colored TIM is typically adhered to the heat sink. Unless damaged, the silver-colored
TIM that is adhered to the heat sink can be reused. If the silver-colored TIM is damaged, use the
supplied scraper to remove the TIM. If you cannot remove the damaged TIM from the heat sink,
you will need to replace both the silver TIM and heat sink. Ensure that you have a spare TIM and
heat sink, part number 01AF286, on hand.
v The other is TIM is dark gray with square corners, part number 01AF742.
The dark gray TIM can be reused unless it is damaged. You will need to move it to the new
system processor module.
