I have a white C2D Macbook (2.0GHz stock) and I have some questions about the heat. It idles between 50-60 which is fine, however, the top right hand side of the keyboard (where the escape key is) feels very warm and also the bottom of the case is very warm. Is this normal? The Magsafe is plugged in - will this make a difference? Also, when I look at the screen (only on the desktop) from any angle below 0 (i.e. looking straight at it but from below normal) I can see a rippling effect. Is this normal? Thanks for your help guys!
