Important: The microprocessor uses a heatsink/thermal pipe to transfer heat away.
Whenever the heatsink is removed, the bottom side of the heatsink and the top of the

microprocessor. If the mating surfaces are not cleaned and thermal paste is not
applied, the CPU may overheat and become damaged. Refer to “Thermal Paste
Application” in this chapter.
