9. If the system uses the gray-colored thermal interface material (TIM): Using the tweezers, remove the
gray-colored TIM from the top of the processor and place it in a clean, dry area as shown in
Figure 124 on page 106. The system can use two types of TIMs. One TIM is silver-colored with
trimmed corners and typically adheres to the heat sink. The other is TIM is dark gray with square
corners and does not adhere. The gray-colored TIM needs to be removed before the processor is
removed.
