Hendrik Holtmann's smcFanControl, a free (but donation-friendly) program released under the GNU public license, just got upgraded to version 2.0. The new version, which now works with all Intel Macs, controls your fan speed while monitoring your computer's internal temperature.
The new version sits in your menu bar (unlike version 1.0, which was a regular dock-based application) and introduces fan setting presets and the ability to detect whether you're running on A/C or battery power. This is a great way to keep your Mac cool while controlling the noise from your fan.
Thanks, Mark Fleser.
