After having installed Lion, one of the things I've noticed is how fast the MBP heats up... and I mean fast. It takes no more than one webpage with moving graphics or a single Vimeo video to speed it up to 80 degrees... Mind you, I redid the thermal paste after I bought the MBP and have had amazing temps... idling at 24 degrees, basic work in the high 30s and youtubing would bring me to high 60s. The only times before Lion I've been getting 80s and 90s have been when I played SC2. So needless to say... Lion temperature management is appalling. Something is wrong and needs to be adressed.
