That may be an issue with the battery health. I'd say run a diagnostic test or take it to a service center. I also suggest installing iStat Nano and see if the battery is doing fine?
EDIT: The noise and heat clearly indicate that the fan has gone. You have no choice but to take it to service center. If it's under warranty they'll change it under the warranty.
And do it IMMEDIATELY!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
