One from Taylor.
We've blogged many a time about the new (or newly ridiculous) problem of laptops that get uncomfortably hot (here and here to link a few). For those who want immediate relief without adding more injection plastic to your collection, try smcFanControl from Hendrik Holtmann. This little free app lets you increase the fan speed on your Mac Intel laptop beyond the OS presets...
If you decide to give the software a try, remember that you're monkeying with one of your computer's fundamental safety functions. It's not quite like command-line Russian roulette, but do exercise caution. Sudo, cool my loins!
Bonus tip: The first time you open smcFanControl, it will disappear from the dock and reappear in the upper right-hand corner of the Finder menu bar. We won't admit how long it took us to figure that out.
