Figure 7-5. Removing a Cooling Fan
NOTICE: When installing a new fan, ensure that the airflow arrow on the
fan is pointing to the rear of the system. If the fan is installed incorrectly,
system components might be damaged due to overheating.
NOTICE: Ensure that the fan’s wiring harness is routed from the side of the
fan when the fan is installed. If the fan’s wiring harness is routed from the
top or the bottom of the fan, the cover will not close properly and the fan or
the wiring harness might be damaged.
6. Press the new fan into its position in the chassis and connect the fan power
connector to a vacant fan power connector in the system board (see
Figure 7-5).
Ensure that the replacement fan is oriented the same way as the original fan.
If you are replacing the fan directly behind the CD-ROM drive, secure the fan with
the two screws you removed with the old fan.
