Cooling Shroud
The system board shroud covers the processor, heat sink, and memory
modules, and provides air flow to these components. Airflow is facilitated by
the cooling fan modules, which are positioned directly beneath the cooling
shroud. The power distribution board shroud covers the power distribution
board behind the power supply bay.
Removing the Cooling Shroud
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 it.
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. The
system may get overheated quickly, resulting in shutdown of the system and loss of
data.
