    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?

    No, there's nothing wrong. If it was going to cause major problems apple would have set the maximum much lower.

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