SMCfanControl For Mac: A free macOS app called smcFanControl lets you control the fans individually built into every Mac desktop or notebook to make your PC run cooler.

Keeping your Mac cool can be challenging

MacOS will also lower the clock frequency to give the processor a choice to run slower and cool off.

Your Mac may also suffer from overheating while running heavy apps or due to background processes such as Spotlight and Photos indexing. Worse, I’ve even had cases when the fans in my MacBook Pro would alternatively begin spinning like crazy. Without any app running whatsoever, due to some old process stuck from prior updates.

The said, I’ve always wish some control over my Mac’s fan speed but I understand why Apple is unwilling to provide such a choice as it could easily lead to CPU failures every time someone who doesn’t know what they’re doing less the fan speed below the minimum.

With smcFanControl, you have total control of the PC’s fans, all the time.

Use it to safeguard set the minimum speed of the left and right fans individually. Personally I liked three customizable presets for when my PC is connected to AC power. Running off its battery or charging, which enables smcFanControl to set different speeds for each fan automatically, when the power source changes.

The app resides in the menu bar, with the icon reflecting the current CPU/GPU/HDD temperature and individual fan speeds. Tap the icon to open the menu and show more information, switch between your default presets, bring up the settings interface and access other choices.

When you off smcFanControl, the PC goes back to macOS’s default fan control.

Is smcFanControl safe to use?

smcFanControl manages and maintains your Mac’s fans responsibly to avoid damaging it. The app ensures whatever value you set is within acceptable tolerances. You cannot set a minimum or maximum speed to value the Apple’s defaults.

For those searching, the minimum default fan speed is 1,000 rpm. For 15-inch MacBook Pro, 2,000rpm for older MacBook Pros with Intel’s Core 2 Duo chip, 1,500rpm for its 13-inch counterpart, and 1,800rpm for the older Core 2 Duo MacBook models.

According to the FAQ, while using smcFanControl to set a new minimum speed, your fan speed will still get a boost (power) when the CPU load gets higher. “smcFanControl lets the fans stay in automatic mode and sets the minimum fan speed”.

Why would I want to use smcFanControl?

smcFanControl has other use cases, like troubleshooting. If your Mac having fan speed issues, resetting the System Management Controller (SMC) may sort out the problem because one of the functions of the SMC is controlling your Mac’s fans.

Many people using the software to increase their fan speed and keep the temperature down versus having to clean dirt that’s blocking fans. The app is specifically useful to creative professionals such as designers, musicians and video editors who work long hours on their PC and want it to stay cool throughout their work.

You don’t require to be a pro to use for smcFanControl, just be a person who has avoided setting a Mac notebook because the bottom is just too hot. Others may simply need some way of controlling the fan speed to fit their various workflows.

A word of warning

To install smcFanControl, drag its icon to your Applications folder after extracting the download. To uninstall, drag the icon into the Trash. As mentioned earlier, the app stops controlling the fans when your Mac turns off, restarts or enters standby mode, in that case, minimum fan speed falls back to the system values.

Before signing off, you’ll be asked to input your admin password when using the app because smcFanControl needs administrative rights to be able to change the fan speed.

Pricing and availability

smcFanControl free to use, but you can make a donation to the developer for their hard work. It needs an Intel-based Mac with a 64-bit chip and Mac OS X Snow Leopard 10.6 or later.
