as i understand ceramic and its application on the shuttle -- it's not an insulator, but its properties associated with handling high temps and dissipation of that heat. so, like a heat sink. and it looks slick as snot. and just as green.
Actually you have it backwards. The shuttle's tiles are such great insulators that you can hold a red hot one in your hand without burning yourself. They are really poor conductors of heat. The heat sink idea was rejected due to the excessive weight required to dissipate the amount of heat generated during reentry.
Uhh... the ceramic materials used in military armor and the space shuttle are made to protect things from heat. They're some of the best heat _insulators_ in the world. In other words, pretty much the worst thing you could possibly use for a heatsink.
My guess is that ASUS is using an entirely different family of ceramic and this Giz poster just chose some poor examples.
@irish_stickman: Huh? I think I must have missed your point.
You always want computer parts to be as cool as possible, since it reduces errors and improves the lifetime of components involved. Just because it can work when it's hot doesn't mean it's a good idea.
@jdickson87: I think what he meant (but poorly explained) is that the ceramic is used to shield the rest of the board from the parts that get hot (CPU, heatsinks/pipes, etc.). Not sure if that is actually what they are trying to do with this board, but I think that is what he meant.
