i have a large film library i intend to put into my itunes, some 70+ HD films. it will take hours and hours and hours of encoding in handbrake. my question is- is doing this in a laptop (my macbook pro) going to break or damage it? im concerned that having the laptop run at high temps with fans full speed for hours and hours regularly will break it. or damage it. i got my 2011 mbp in march. i already notice that one of the fans has gotten nosier over time unlike when new. it seems to be normal when the laptop is flat down on a surface, but if i elevate it in different angles horizontally the noise comes in. sounds like a gentle grinding whine. anyone advise me on wether its safe or bad?
