smcFanControl is a free fan control utility for mac powered by Intel. The app lets you increase the speed of inbuilt fans to make your system run cooler. Along with it, you can use it to monitor Temperature and fix overheating issues.
All the Mac’s ship with a default fan speed for all inbuilt cooling fans. It rarely happens that these settings fail to cool the PC and keep it running. But of your computer has become old, it can happen.
While working or playing if you Mac hangs, crashes due to overheating use this tool to increase your Minimum fan speed to make it cooler. High CPU temperature makes high-performance apps crash. Monitor CPU, HDD, and ODD fan speed and adjust their RPM using the slider in front of them.
You can set different minimum speed for ODD, HDD, and CPU fans. Running a fan at low or high RPM is easy with the slider. Try not to play with it, use with caution.
It also includes a menu bar monitoring panel. You can change Menubar elements in smcFanControl settings. For reference see the screenshot below. In this, I have selected temperature and RPM both to show in Menubar. Click or tap Preference to change settings.
smcFanControl temperature monitoring lets you switch between Farenheight and Celcius. So, you can choose a temperature unit that you prefer.
The features don’t end here.
Under the options, you can select “Autoapply favorite when powersource changes” option to apply different minimum fan speed depending upon the power source. It supports all the three modes Battery, Power, and Loading.
smcFanControl uses default fan speed setting when your Mac is running on battery. Cools your Mac without reducing the power backup duration.
However, in order not to damage your machines, smcFanControl doesn’t let you set a minimum speed to a value below Apple’s defaults. smcFanControl never lets you set a minimum speed (basically Apple’s default) than can damage your Mac. Takes care of your Mac and prevents it from the risk of burning out.
The software is easy to use but requires certain precautions before making changes. You should read Apple’s guidelines or Intel’s specification of the processor.
This app will not work on non-Intel PCs. But in Intel also only 64-bit version is supported. The support for 32-bit Macbook is not available. This will not affect most of the users as the new Macbooks comes with 64-bit chips. You should check for it if you have an old system.
The latest version adds support for all current MacBook, MacBook Pro, MacBook Air, and Mini.
