Cooling Fans
Your system supports hot-swappable cooling fans.
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 cooling fan
assembly.
Removing A Cooling Fan
WARNING: Opening or removing the system cover when the system is on may expose you to a risk of electric
shock. Exercise utmost care while removing or installing 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.
CAUTION: The cooling fans are hot-swappable. To maintain proper cooling while the system is on, replace only
one fan at a time.
CAUTION: Do not operate the system with the cover removed for a duration exceeding five minutes.
NOTE: The procedure for removing each fan is identical.
1. Open the system.
2. Press the fan release tab and lift the cooling fan out of the cooling-fan assembly.
