Cooling Fans
Your system contains five single-motor fans and provides cooling for the
processor, expansion card, power supplies, and memory modules.
NOTE: Hot-swap removal or installation of the 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 fan.
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.
NOTE: The procedure for removing each individual fan module is the same.
