What is the big thing that protects the CPU?

You must be referring to the CPU heatsink/fan assembly. Modern CPUs generate so much heat that it is necessary to provide cooling in order to prevent damage. The heat sink is a metal piece which mounts directly on top of the CPU, through physical contact the heatsink draws heat from the CPU into itself. The top of the heatsink is designed to have as much surface area as possible in order to maximize heat dispersal.
Usually a fan is then mounted on top of the heatsink in order to further increase its cooling ability.
