Figure 37: Removing/replacing the chassis fan
4 Remove the fan from the chassis.
To replace the chassis fan
1 Position the fan against the chassis.
An arrow on the side of the chassis fan indicates the airflow direction. Make sure that the chassis fan is positioned
with the label against the chassis. The chassis fan should blow air out of the vents in the connector panel when the
system is reassembled and powered on (see Figure 37).
When correctly positioned, the fan cable should reach FRONT FAN connector (J30) on the motherboard.
2 Align the four holes on the fan with the four holes in the chassis, and replace the four rivets that secure the fan to
the chassis.
Hold the fan firmly against the chassis, and push each rivet all the way until it snaps into locked position. Make sure
that the fan is tightly secured to the chassis.
3 Connect the 4-pin fan cable connector to FRONT FAN connector (J30) on the motherboard.
The cable connector is keyed to fit only one way.
