Memory Cage with Rear Fan
The rear fan is part of the memory cage assembly. If you need to replace the rear fan, you must
replace the entire memory cage assembly.
Note: Every time you remove the memory cage, you must replace the thermal grease on
the processor heatsinks. New grease and alcohol wipes for removing the previous grease are
available as a separate kit (part number 076-1225). Instructions for applying the grease are
included with the processor heatsinks procedure.
Tools
The only tools required for this procedure are pliers, wirecutters, and a socket wrench.
