Removing and Replacing the Cooling
Shroud
The plastic cooling shroud inside the system is used to improve airflow over the
microprocessors. You may need to remove this shroud to access certain components
on the system board.
Removing the Cooling Shroud
To remove the cooling shroud, perform the following steps.
NOTICE: Observe the information given in “Precautionary Measures” and
“Before You Begin” to ensure that the system configuration screens are
recorded and the system is properly shut down and disconnected from all
power sources.
1. Turn off the system, including any attached peripherals, and disconnect the power
cable from the electrical outlet.
2. Remove the right-side computer cover.
3. Unscrew and remove the two retention pins (see Figure 1-9).
4. Remove the shroud by lifting the end of the shroud closest to the microproces-
sor(s) until the opposite end of the shroud disengages from the cooling fan on
the system back panel.
