To reinstall the CPU fan and heatsink assembly:
1. Position the CPU fan and heatsink
assembly on top of the installed
CPU.
3. Connect the CPU fan cable to the CPU fan connector on the
motherboard.
2. Hold down the heatsink lightly and
twist each of the four screws with
a Philips (cross) screwdriver just
