Figure 4-11. System Cooling-Fan Removal
To remove the system cooling fan, follow these steps:
1. Lay the computer on its right side.
2. Disconnect the system cooling-fan cable from the FAN connector on the
system board (see Figure 4-12).
3. To loosen the system cooling fan from the chassis:
a. Push the plunger of each of the four push-fasteners toward the back of
the chassis, using a small flat-blade screwdriver (or another small flat
object).
b. From the outside-back of the chassis, pull the plungers completely out
of the push-fasteners.
4. Remove the system cooling fan and the push-fastener barrels from the
chassis.
To replace the system cooling fan, use four new push-fasteners. (New push-fas-
teners have the plunger inserted part-way into the barrel.) Align the mounting
holes in the system cooling fan with the holes in back wall of the chassis. Insert
each push-fastener completely; then push in on the plunger to lock the fastener.
