Finishing Installing the Heatsink
After you have finished installing the heatsink onto the processor and socket,
attach the end wire of the fan (which should already be attached to the heatsink)
to the motherboard. The following diagram illustrates how to connect fans onto
the motherboard.
Once you have finished installing all the fans you can connect your drives (hard
drives, CD-ROM drives, etc.) to your motherboard.
