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.
