Cooling Shroud
The cooling shroud covers the processor, heat sink, and memory modules,
and provides air flow to these components. 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.
The system may get overheated quickly, resulting in shutdown of the system
and loss of data.
Removing the Cooling Shroud
Turn off the system and attached peripherals. Disconnect the system from
the electrical outlet and peripherals.
Open the system. See "Opening the System" on page 79.
Remove the expansion card stabilizer. See "Removing the Expansion Card
Stabilizer" on page 81.
Remove the cable secured into the bracket on the side of the cooling
shroud. See Figure 3-6.
Hold the touch point and rotate the cooling shroud 180° away from
the chassis. Page 82 Monday, August 9, 2010 3:07 PM
