● To replace the chassis fan
1. If you are installing a new chassis fan, attach the fan guard to the correct face of the new fan.
Use the fan guard and four rivets that you removed from the old chassis fan. Position the guard against the face of the new
fan so that the airflow arrow on the fan points toward the guard (see
“To remove the chassis fan” on page 37 ). Push each
rivet all the way through its mounting hole until the rivet snaps into the locked position.
2. Take off the fan cable from the cable line hole.

3. Position the fan against the chassis.
When correctly positioned, the fan guard on the fan should face the motherboard, and the fan cable should reach its connector
on the motherboard.
4. 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 (see below figure).
Hold the fan firmly against the chassis, and push each rivet all the way until it snaps into the locked position. Make sure that
the fan is tightly secured to the chassis.
