When the temperature of your computer rises, the MacBook fan starts working quickly, especially when it is running for a long time. Using applications that consume resources will also lead to this, but in any case, if you want to get rid of the loud sound in the fan of any MacBook computer, you must follow the following explanation.

Why does the MacBook fan make noise? If your MacBook's fan is running very loudly for long periods of time, there is a problem. For many MacBooks, they need fans to spin to keep the device cool. This is normal.

But if your Mac's fan starts spinning very loudly from time to time, this indicates a problem that must be solved in order to get rid of the annoying sound. How to solve the fan sound problem? There are 5 proven ways to solve the problem of fan sound in MacBook devices. You may need to follow all the steps in order to get a quiet and pleasant fan sound.

These steps will not only help you reduce the fan noise, but will also maintain the longest possible life of your MacBook. 1- Check your open applications and tabs. The more applications and browser tabs you have running, the more your Mac needs to use the fan to keep the components inside it cool. Reduce the number of tasks your computer is doing by closing applications when you're done using them, especially when using graphics-intensive applications like Photoshop and iMovie.

To see which apps are using the most CPU resources, open Activity Monitor and click the CPU tab. Keep in mind that Chrome is one of the most resource-intensive applications on MacBooks, so you should try a less resource-intensive web browser. 2- Removing obstacles in front of the ventilation openings. The MacBook Pro contains ventilation openings on its sides and back edge, and the MacBook Air contains openings along the back edge.

These vents draw in cold air and expel hot air. If you block these vents by placing your laptop on your lap, on a pillow, sofa, or blanket, your Mac will certainly heat up quickly. Place the laptop on a table, or on a hard, flat surface to allow air to freely enter and exit through the ventilation holes. If dirt accumulates on the openings of your MacBook, this may obstruct the entry and exit of air into the device, so you must clean the dust from the openings. However, if the dirt accumulates greatly and is difficult to remove, you must open the device and clean it from the inside.

Use a small screwdriver and remove the bottom panel of the MacBook to clean any dirt or dust that may have accumulated on the computer’s internal components during periods of use. Use a can of compressed air to remove dust, or a clean cloth to gently wipe the components.

Pay special attention to the cooling fan itself, and its vents, while cleaning the entire back edge of your particular MacBook. The goal here is to clean the internal components to achieve maximum airflow possible. 4- Use error checking tools. There is a possibility that the reason your MacBook is overheating is because there is something wrong with the cooling fan itself. You can check this by using Apple Hardware Test tool

Or the Apple Diagnostics tool, which is designed to troubleshoot errors in MacBook computers and provide you with some repair steps. You can make use of these tools, or turn on your MacBook and remove all external peripherals, then reboot it and hold down the D key to start any diagnostic program.

Follow the on-screen instructions to start the test. The standard test takes just a minute or two to complete and will report any issues with your device. For a more comprehensive scan, you can check a box for an extended test that will take an hour, or more, to complete. You will see 3 codes related to the cooling fan, starting with PPF. If you see one of the results that starts with PPF, this means that there is a problem with the fan, and you must take it to the specialized maintenance center.

5- Reset SMC If your Mac is clean, free of dirt, you are not using a lot of applications, you are not opening many tabs and the fan is still spinning frequently and loudly. Try resetting the System Management Controller (SMC). The SMC is responsible for controlling low-level functions on your MacBook, including thermal management, also known as the cooling fan. Follow Apple's instructions that appear in front of you to reset the SMC correctly, and thus you will get rid of the problem of the MacBook fan being loud if you follow all of the tips mentioned above.
