    I am stressing the CPU right now, running two instances of yes > /dev/null in terminal. CoreDuoTemp is showing the temp at 79 Celcius, 100% CPU Usage. Its been like this for 5 minutes, but the fans haven't turned on (or atleast I can't hear them).
    Is this normal? Its not like the laptop is unusually hot or anything, so for that reason I don't really care, I am just wondering however.

    I don't own a MBP, but should your computer not turn off if it reaches unacceptable heat levels. Before the new Intel Macs, I would never check the temperature because it would drive you insane, but now... I am not sure. How long have you been running it like this?

    Mac Book Pro Temperature Gauge: Place an egg on the left palmrest, and a piece of bacon on the right. If the bacon cooks before the egg, you may have a problem. :p

    Yep normal, if the CPU reaches 125 Celcius your MBP will shut down automatically. So no worries, it's just hot :)

    they turned on, after 7 minutes. Never went over 81 Celcius. I heard the fans, and temp started to drop, down to the low 70's. Also noticed the CPU speed dropped, from 2167mhz to like 1667mhz.

    Mine come on at 80c They are very very quiet (didn't even hear them) initially, and with continued load get a bit louder.

    Makes your CPU run at 100%. If you have two cores you have to open two terminal windows and type it in both console windows. Then both cores will run at 100%.
