Cooling Fans Your system contains four cooling fans, single- or dual-motor depending on your system configuration. These provide cooling for the processor, PCI cards, and memory modules. Systems with redundant power supplies also contain one single-motor fan to provide cooling for the power supplies. NOTE: Hot-swap removal or installation of the cooling fans is not supported. NOTE: In the event of a problem with a particular fan, the fan number is referenced by the system's management software, allowing you to easily identify and replace the proper fan by noting the fan numbers on the fan assembly. Removing a Cooling Fan WARNING: The cooling fan can continue to spin for some time after the system has been powered down. Allow time for the fan to stop spinning before removing it from the system. WARNING: Do not attempt to operate the system without the cooling fans. 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. 1 Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. 2 Open the system. See "Opening the System" on page 66. 3 If applicable, remove the cooling shroud. See "Removing the Cooling Shroud" on page 68. 4 Disconnect the fan's power cable from the system board.
