That is extremely hot.
Sounds like the fans might be coughed up and aren't circulating the air well, even though they are running at 6000rpm. My MacBook Pro's logic board got replaced, and before, the fans would be going 6000rpm when CPU usage was pretty much 200% and the CPU temperature was around 91'C. They said the fans were in a bit of a mess when they replaced the logic board.
Now, when encoding video, the temperature never goes above 80'C, usually 74'C average and the fans rarely go above 4000rpm to keep it at that temperature.
I know you are running an older generation MacBook Pro, so the CPU will reach different temperatures to mine, but I'd make sure your fans aren't clogged up (either clean yourself if you are out of warranty, or an authorised vendor).
