MacBook Pro :: 13 Inch Core Temp - Is It Dangerous

My question is this, is it normal for core temps to sit as high as 90 - 100�C while doing things like rendering video and gaming. For example, I was playing the Sims 3 for the first time the other day, and the core temps sat at about 95�C while playing. Is this a normal temperature? or is it something I need to be worried about.

I've already downloaded SMCfancontroller and use it whenever I'm doing something like encoding a DVD. I'm just overly concerned that I might cause some damage if I let it get around 100�C too often.
