Is anyone experiencing this as well? I have encounter the same problem a few times now. My macbook would have it's fan keep running even when the lid is closed. Isn't it strange? I haven't had this problem before in Snow Leopard. In snow leopard, even when the fan is running at 6200rpm, as soon as I close the lid. My macbook would be quiet almost instantly. However, with Lion my fan and processor would keep running. Anyone else? any idea?
