Removing a Cooling Fan Module

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.

1Turn off the system and attached peripherals, and disconnect the system from the electrical outlet and peripherals.

2Open the system. See "Opening and Closing the System" on page 46.

NOTE: You can remove the fan modules without removing the memory cooling shroud; however, Dell recommends that you remove this shroud before removing a fan module. Do not remove the system board cooling

shroud. See "Removing the Memory Cooling Shroud" on page 52.

3Raise the fan handle, disconnect the module wire harness from the system board, and pull the fan straight up to clear the chassis. See Figure 3-4.

4Unplug the fan module connector.
