While its a very smart idea to add the anti-overheat feature, it still is stupid to create the possible scenario in the first place.
It really isnt' that hard. You know the temps possible from the system and what the components can handle. From there you devise a way to absolutely be certain it cannot overheat under normal operating conditions.
Since a great abundance of homes use entertainment centers, I would think a shelf that is mostly closed should be considered a normal operating condition.
My Wii, Onkyo AV reciever, and Cable box operate without any heat issues with my glass doors closed on my center. However, when I play PS3 games and even movies, I have to keep the door open to keep the PS3 from kicking into high gear.
That's stupid. High end components or not; my setup is not unique by a long shot.
