I would recommend using an oven with your Pi, not frying it. Fried Pi’s are a little crispy and often end up cold in the centre. :D
cough, joking aside, according to this, you should be fine, as long as you have it adequately cooled. Of course, there’s always the issue of reduced SD card life if you’re constantly read/writing to it, but that’s an unrelated issue to CPU usage.
I would recommend adding some kind of cooling fan as well, just to make sure. :)
Oh, and don’t forget the go-faster stripes!
