Cooling fans
Your system supports hot-swappable cooling fans.
NOTE: If a fan fails, the fan number is referenced by the system management software. This allows
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. Remove the system cover.
