How To Stop Fan On Macbook Air

At times, you might notice that the fan on your MacBook Air won’t stop running. This can be due to a variety of reasons, from your MacBook trying to keep cool to itself due to heavy use, to software glitches. Whatever the reason, it can be distracting and even worrying. This blog post will guide you on how to stop the fan on your MacBook Air.

Method 1: Restart Your MacBook Air

Often, the simplest way to stop your MacBook Air’s fan is by simply restarting the device. This process can refresh the system and clear out any minor software glitches that might cause the fan to keep running.

Method 2: Check Your Applications

Heavy usage of applications can cause your MacBook Air to heat up, leading to the fan being in constant operation. Consider closing unnecessary applications to lower the CPU usage. To view all running applications, you can use the following steps:

1. Press Command + Space to open Spotlight.

2. Type ‘Activity Monitor’ and hit enter.

3. Click on the ‘CPU‘ button and find out what application is causing the high CPU usage.

Method 3: Reset the System Management Controller (SMC)

If the above methods didn’t work, resetting the SMC may help. The SMC controls several functions, including fan control. Here’s how you can reset the SMC:

1. Shut down your MacBook Air.
2. Press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.
3. Hold these keys and the power button for 10 seconds.
4. Release all keys and the power button at the same time.
5. Press the power button again to turn on your MacBook Air.

After resetting the SMC, your MacBook Air should run smoother and the fan should stop running non-stop.


The fan of your MacBook Air plays a vital role in keeping your device cool. However, if it’s running constantly, it can be a sign of an issue. By following the above methods, you should be able to easily stop the fan on your MacBook Air.

If none of these methods work, it might be a hardware issue and you should consider taking your MacBook Air to an Apple Store for a check-up.
