CCBs have better heat dissipation capabilities than cast irons, so they cool down faster (this is why they have better resistance to fade). But while in operation (during braking), they do run much hotter than cast iron ones.
Not quite. The primary reason CSiC brakes are more resistant to fade is because they are mated to a brake pad that is able to operate at higher temperatures. Fade, in any form, with any rotor is a pad phenomena, not a rotor phenomena.

Brake temperatures (rotor and pads) fluctuate (obviously) with the application of brake loads and the period in between when they are only cooling with no applied loads. Despite cooling better CSiC brakes also heat up more for a given brake load. If it were not for a matched pad designed to deal with these higher temperatures, this particular feature of a CSiC rotor (very light weight) actually makes them more fade prone. Again to be clear, not necessarily more fade prone than some base non CSiC system, but simply more fade prone than if they operated at a cooler peak/average temperature.
