Cool down your MacBook (Pro)
Can you hear your MacBook's fan whirring a bit too loud? This means that your Mac is overheating and that you are putting too much strain on it. This can be caused by applications that use up a lot of your computer's resources or is simply the result of having your Mac on for too much time.
Fan Control lets you adjust your fan's speed and thresholds to adapt it best to your Mac's current temperature. Thanks to sliders, you can set the lower and upper thresholds and base speed. A graph on the right of the interface shows you the speed to temperature ratio. If you move the different settings around, you'll see it adapts, never passing the original automatic fan speed.
Although it might be a bit difficult to tell which speed and thresholds are right for you, you can try out a few settings and see if your fan stops making sounds.
Fan Control is a handy preferences pane which allows you to adjust fan speed and thresholds to your MacBook's temperature.

Beware of this app! It can damage your SMC!.
Seemed like a nice concept and it really kept my temperatures down on my rMBP up until I booted into Windows. Windows 8 started acting strange; menus would lag, Metro would freeze, fans wouldn't come on under gaming, and I wouldn't be able to connect to WiFi. I couldn't figure out what the problem was, so I just tried uninstalling this app, and Windows started behaving normally again! However, even after multiple SMC resets, now smcFanControl (which I used prior to this app) doesn't change the fan speed, which makes me inclined to think that my SMC is permanently altered. So, it's a nice concept (I really liked that you can adjust the temps vs. fan speed graph) but in practice it really doesn't work. And now, the older app I used doesn't work and the fans don't speed up as fast, so my SMC is damaged. Beware of this app... More

Nice!.
When I render animations in Blender, the Temp goes up to 81.5 C but the fans seemed to stay around 2000rpm. I doubted this was healthy, and thanks to your program, I've made the fans go up to 5000rpm, and it keeps the temp of my computer to about 70 C!
Pros:
I found the settings to be easy to manipulate and intuitive
Cons:
Uninstalling does require you to fish out files and reset the System Management Controller (SMC). More

Awesome.
When i first downloaded this and installed it, i thought it was a virus because i couldnt find where it installed to but after i found it in the preferences and used it, i loved it. Instead of going into the 70's when i play games, it stays in the 50's (c) thank you so much for this app, it really kept me from being worried about my mac mini's temp. Oh and btw, the mac mini 2.5 ghz can run games max setting with antialiasing 16x and anisotropic filtering maxed out
Pros:
kept my mac cool after playing some hardcore games
Cons:
couldn't find it at first so i thought it was a virus More
