into position.

the bottom of the heatsink and place the fansink assembly into the metal bracket

on the system board assembly and secure the ends of the wire loop under the

edge of the metal bracket.

2. Plug the new fansink into the system board connector of the old fansink.

3. Reinstall the disk drive bracket assembly.
