I do lots of dvd/cd encoding to keep backups of everything of my harddrive; so I use handbrake fairly often. During encoding, CPU usage goes all the way up, temperature is stable around 86-90 degrees centigrade, and the fan runs at around 6150-6200 rpm. (MB C2D 2.16)
Now someone whose knowledge I trust has just posted a blog entry where he says that "6200 rpm is too fast/too dangerous"; he doesn't specify exactly why, and under what conditions; nevertheless this bothers me a little. For months now, I've been encoding dvds, and my fan has been running at 6200rpm with no problem----well, with a single problem really: At lower speeds, sometimes it makes a loud and irritating noise. The noise comes and goes by itself; and as I simply don't have the time, I haven't taken my MacBook to the Apple Store.
Anyhow: At full CPU usage, there's nothing wrong with the fan running at 6200 rpm, is there?

I burned a DVD yesterday to import into iTunes, and the fans were running at about 5700rpm.
