How To Make Your MacBook Pro Cooler


How To Make Your MacBook Pro Cooler

If you own a MacBook Pro, then you know how hot it can get. In fact, before I started writing this, I had my MacBook Pro on my lap, but couldn’t take the heat anymore — right now I have it on my kitchen table while steam continues to rise from my legs. Fortunately, a user on MacRumors Forum has come up with a way to make it cooler. The user claims to reduce the heat by 40-50° Fahrenheit by tweaking a system extension.

My original post had instructions on how to make the change, but the author of the tweak created an AppleScript that does it for you. One thing to keep in mind is that the changes revert back to their original settings when you reboot. Tyler assures me that it’s only a matter of time until someone creates a more elegant solution. When that happens, I’ll post it here.

Update 1

(Friday, October 13th, 2006)

smcFanControl 1.1 has been released. It’s an application that let’s you:

  • Let’s you set the minimum speed for each fan individually
  • Adjust fan speed until the Macbook(Pro) is finally comfortable on your legs again
  • Auto apply mode to set the new fan-speeds after a restart
  • Sourcecode included! Extend it and change it to your needs


Update 2

(Thursday, October 19th, 2006)

smcFanControl 1.2 has been released. Other than fixes, it now monitors temperature.


Update 3

This app is now up to version 2.3

smcFanControl is now up to version 2.3, I just deployed this app and decreased the temperature by 4 degrees in the first 5 minutes. Still a great application.
