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: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
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.
