Cooling Fans

Your system contains four dual-motor cooling fans. These provide cooling for the processor, PCI cards, and memory modules. Your system also contains 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
