Finally, restart your computer and check if resetting the fan has resolved your issue. If not, consider cleaning out any dust from within your laptop using canned air or a vacuum cleaner with an extension hose attachment for hard-to-reach areas such as around fans and vents.

Reasons for Constant Fan Running on MacBook Air
The fan on your MacBook Air may be constantly running due to a variety of reasons. Dust buildup can cause the fan to run more often, as it prevents air from flowing freely through the vents and requires extra cooling power. Heavy GPU use can also cause the fan to run constantly, as the graphics card needs more cooling power during extended periods of use. Additionally, regular wear and tear on components such as the hard drive or processor can cause additional heat production which will require the fan to work harder to cool down your Macbook. Finally, it could be that your Macbook is simply running too hot and needs additional cooling power – this may indicate a problem with your system’s thermal management system.
Sudden Increase in Loudness of Mac Fan
The sudden increase in noise coming from your Mac’s fan is likely due to an accumulation of dust on the internal components. Over time, dust can build up on the motherboard and other components, creating a blanket-like cover that restricts airflow and causes your Mac to overheat. This can cause the fan to kick into overdrive, resulting in louder-than-normal noise coming from your computer. To reduce this loud fan noise, you’ll need to remove the dust buildup in your Mac. You can do this by using compressed air or a vacuum cleaner with a soft brush attachment to gently clean off any dust that has accumulated.
Fixing the Fan Speed on a Mac
Fixing the fan speed on your Mac is fairly straightforward. First, you’ll need to download and install Macs Fan Control (MFC). Once installed, launch the application. In the MFC window, click “Custom” next to a specific fan. Then, use the slider to set your desired fan speed. Finally, click “OK” to save your changes. That’s all there is to it!
Turning Off the Fan Noise on a Mac
To turn off fan noise on your Mac, you should first check to ensure that the vents are not blocked, otherwise, your Mac will overheat and cause the fan to become louder. Additionally, you should check the ambient temperature to make sure it’s not too high. To prevent overheating, try freeing up memory and resetting the SMC. You should also ensure that your version of macOS is up-to-date. If these steps don’t help, try cleaning the fan dust and controlling the fan speed manually. Finally, free up hard drive space if possible as this can reduce fan noise as well.
Conclusion

It is important to note that the MacBook fan always on an issue usually doesn’t indicate anything serious and can be fixed without much hassle.
