The rims can overheat. For this reason they have been banned in competitions before, and are viewed by many to be unsafe. Braking isn't as good and requires special pads, and carbon fibre spokes snap like spaghetti. All for a small weight saving; indeed some carbon fibre wheels aren't even particularly light. Unless you are racing at a pretty respectable level (i.e. such that an aero wheel is actually more advantageous than a lightweight low-profile rim), I cannot see why as an amateur you would want them, and I have to wonder how many professionals would be using them - even in competitions - if they had to buy their own wheels and didn't have a service car a few metres behind.
I can see your point, but what makes a clincher rim overheat but not a tubular? What about carbon rim clinchers but wi alloy braking surface like dura ace c35/50?
The two are different designs, and carbon fibre clincher rims by nature of their construction do not dissipate heat as well. Both are susceptible to this problem, though; it just so happens that the pros don't need to care very much!
