Turbo Boost Switcher

[For Mac users.]

Rubén García Pérez’s Turbo Boost Switcher is a tiny app that enables or disables OS X’s Turbo Boost. Turbo Boost is the technology that increases CPU speed (and with it, fan speed and temperature). You know what it’s like when your Mac heats up and the fan goes at full blast? That’s Turbo Boost at work. Disabling Turbo Boost lengthens battery life and and allows a Mac to run at a significantly lower temperature. Turbo Boost Switcher is available in free and Pro versions.

Full disclosure: this blog post will get me a modest discount on the Pro version’s already modest price. Further disclosure: I’ve been planning to write a post about this app anyway, for many months now. I learned about Turbo Boost Switcher, more than a year ago, from Marco Arment’s blog, and have been using it ever since.
