Cooling Shroud
The cooling shroud directs airflow over the system processor and memory
modules.
WARNING: The memory modules and heat sink can get very hot during normal
operation. Ensure that the memory modules and heat sink have had sufficient time
to cool before you touch them.
CAUTION: Never operate your system with the cooling shroud removed.
Overheating of the system can develop quickly, resulting in shutdown of the
system and loss of data.
