Hi there

I did some video/ after effects stuff on my nTB MBP 13'' and the cpu went nearly 100 celsius and the fan still didn't kick in. The chassis & keyboard were really hot.

Had to use the app TG Pro to manually start the fans to cool it down.

How hot does it have to get until the fan kicks in?

100c is hot but not that bad. i would get worried around 150c. Make sure the machine is sitting on a flat smooth surface of course. The aluminum will act as a heat sync so it will get hot. Doesn't hurt to use Mac Fan Control to set a minimum, i use it on my 2011 15" mbp to keep the GPU in one piece
