25. Use this step to install a new silver-colored TIM and the heat sink.
a) The thermal interface material (TIM) is typically adhered to the heat sink.
• If the old TIM cannot be easily removed from the heat sink, use the supplied plastic putty knife
to scrape the TIM from the heat sink.
• If the TIM cannot be removed from the heat sink, or if you are unsure about the old heat sink, do
not reuse the removed heat sink. Use a new heat sink
b) Open the TIM packaging and carefully remove the TIM, holding it by the edges of the carrier strip
and holding it away from the shipping container.
c) Remove the protective film from the clear carrier strip by using the supplied tweezers.
The TIM must remain flat. Small wrinkles are acceptable, but folds are not acceptable.
d) Using the tweezers, remove the TIM from the carrier strip and center it onto the system processor
module.
The silver-colored TIM must have the red stripe up. Align the beveled corners of the silver-colored
TIM and the system processor module (A), as shown in Figure 134 on page 154.
Use the alignment marks on the top of the system processor module to properly place the TIM.
You must center the TIM in the alignment marks on the system processor module.
