Removing an adapter is the reverse of installing it. Note that if you remove an adapter and you do
not replace it with another one, you must install an I/O slot cover on the back of the chassis to
ensure that your system continues to cool itself appropriately when it is running.

Removing and Replacing the Fan Assembly

When the side cover is removed, you can remove and replace the auxiliary fan assembly that cools
the processor and memory. Removing the fan, or removing the complete fan assembly, is
necessary to access memory. Before removing the fan or fan assembly, ensure that the safety
precautions stated for removing the side cover have been observed.
1. To remove the auxiliary fan from its mounting bracket, disconnect the fan wiring harness,
squeeze the fan mounting tabs toward the center of the fan, and withdraw the fan fom the
bracket.
2. To remove the fan bracket, remove four screws. Two screws hold the bracket to standoffs on
the motherboard, and two screws hold the bracket to the back of the chassis.
Replacing the fan and fan assembly are the reverse of removing them. Ensure that the fan wiring
harness is connected before replacing the side cover.
