Historial para "Why is my laptop so hot?"

I've noticed that the bottom of my laptop gets extremely hot, nearly burning to the touch. I have a fan in the laptop and can hear it operating when I turn on the laptop but it continues to get really hot. Can a fan's function deteriorate or is there possibly something blocking the fan from working at its full potential? Or is there something else causing the laptop to heat up?
