• Displays temperature and fan speed in the menubar

• Apply different fan-settings with just one click

• Let's you set different minimum speeds for every fan seperately and save them as favorites

• Autoapply different fan settings when the powersource changes (macbooks only)

• Sourcecode included! Extend it and change it to your needs
Approach of the program:

smcFanControl lets the user set the minimum speed of the build in fans.
So you can increase your minimum fan speed to make your intel mac run cooler.

However in order not to damage your machine scFanControl let's you not set minimum speed to a rate under Apple's defaults. In addition to that fans are still in automatic mode, so the speed of your fans will increase, if CPU load gets higher.
