Removing and replacing the processor air duct
You must remove the air duct to access the processor assembly, four-fan
assembly, and the memory modules. Because the processor air duct
channels the airflow within the chassis, be sure to reinstall the air duct
before installing the chassis cover.
Requirements
You need a Phillips (cross head) screwdriver, #1 and #2 bit.
