my mbp certainly has the heat issue. when i'm running "yes > /dev/null" in two terminal windows (so as to work both cores), i reach 95 degrees celsius in about 60 seconds. i know laptops can get hot, but that's ridiculous. the core duo spec says under 100 is fine, but that's not what i'm worried about. i'm worried about it burning my hands.

also, the cpu whine does not happen if you boot into windows with boot camp. so personally, i'm more inclined to believe it is not a problem with the cpu.
