How To Manually Control Mac Fan Speed

Do you want to Manually Control Mac Fan Speed? Apple can’t open its hardware to developers or users very easily. Also, it goes for some of its hardware i.e TV, desktop, and phones. However, it can’t be as limited probably like. For example, you can install apps from outside the Mac App Store using little to no effort that is something you can’t do on an iPhone.

On a Mac, you can easily control the speed of fan speeds manually. Apple can’t provide you a tool to do it. But there are some third-party apps that you can use. Come let’s check how to control Mac fan speeds manually.

Manually Control Mac Fan Speed

The fan(s) keeps a Mac temperature cool when it overheats, for some reason. Also, it can damage the hardware.  Make sure the damage can’t be covered by any warranty.

Macs Fan Control

If you want to control the fan speed, simply install an app called Macs Fan Control. Remember to move the app to the Applications folder before you execute it. You’ll then view the following interface. The number of fans that you view will quite differ. Also, it is based on the Mac version you’re using. Some Macs have 3 fans, others only have one.


You will then view a list of sensors in the right column. However, these sensors can also measure temperature that can be instrumental in how to modify the fan speed.


One last thing you must remember is that fan speeds are set in RPM i.e., rotations per minute. However, higher RPM means the fan runs faster. Also, lower RPM means it runs slower.

If you want to control a fan’s speed, simply run the app and follow the steps below carefully:

Step 1:

Initially, you’ll view all the fans that are on your Mac. Make sure the Current/Min/Max values for a fan. These are all the RPM values.

Step 2:

Choose a fan and tap the ‘Custom’ button next to it.

Step 3:

There are two methods to control the speed of a Mac. These methods are RPM, and sensor-based. In the panel that opens when you tap ‘Custom’, the RPM choice is chosen by default. Using RMP, simply input value but the value will have to be within the Min and Max values that you remember in the first step.

Step 4:

If you don’t use RPM values to check the speed, you can then set it to be temperature based. Simply choose the Sensor-based choice.

Step 5:

You will then view a dropdown that will list the sensors on your Mac. However, the fan speed can be set to the temperature of the sensor you choose. Select one from the list, then set a Min and Max temperature that will trigger the fan to run faster. Then tap OK.

Troubleshooting fans

While this is generally safe, you can run into issues using the fan also if you aren’t modifying how they work. Suddenly, if your fans are running fast when they can’t, running constantly, or not running at all, then you’re going to have to resolve the issue. To resolve the issue, simply perform an SMC reset or a System Management Controller reset.

Desktop Mac/iMac

Step 1:

At first, shut down the Mac.

Step 2:

Then unplug it.

Step 3:

Then wait for few seconds i.e 15 – 20 seconds.

Step 5:

Again wait for another 5 seconds.

Step 6:

Step 1:

At first, turn off the MacBook.

Step 2:

Make sure you do not disconnect the power adapter. But if it isn’t connected, then connect it.

Step 3:

Now hold down the Left Shift key + Control + Option + Power button all simultaneously for few seconds.

Step 4:

Now release the buttons and wait for 5 seconds more.

Step 5:

Click the Power button to enable the MacBook, and your fans should be back to a normal state.

Managing heat and fans

If you want a single fan on your Mac, it probably simple to manage it as you know it’s the only thing that making it cool. If you have more fans, then it means cooling is categorized between them. Also, you’ll have to look at many various regions to manage the heat effectively. Using various fans, it’s quite possible that a single fan can’t access to all the sensors on your Mac. In that case, simply keep an eye on various sensors and the temperature of different regions. It’s not quite easy and it’s the best idea to check how heat flows in your Mac version before you proceed further.


Here’s all about “Manually Control Mac Fan Speed”. Generally, Macs have done a good job of managing how hot or cool they run. Certainly, they can’t hear the Mac is shutting down due to its overheated. However, the same can’t be said for Windows computers. Also, Macs can’t be used for gaming but they are certainly the go-to system for design and animation. Not just this but also those apps run the Mac hot so it probably helps to know how to manually manage the heat on it. Make sure if your Mac is running too hot and it doesn’t have anything to do using your apps, then you must know taking it in for a check.
