Your Macbook’s fans are responsible for keeping the device cool and preventing overheating. So, they play a big role in maintaining your Mac’s speedy performance. Loud cooling fans usually indicate that they are working harder to keep your device cool. However, that is not always the case, and you might sometimes want to check for damaged fans.
Regardless of the reason for this issue, you can troubleshoot it by yourself in most cases. In case of hardware damage, you must call a technician immediately for a repair or replacement. Try out the fixes given here before you contact a professional for help.
6 Ways to Fix Loud Macbook Cooling Fans
The cooling fans will often work loudly when your Mac is running a heavy task. You must also consider other possible causes for that and apply the necessary solutions. Here are the simple ways to troubleshoot a loud Macbook effectively:
-
Check and Reduce CPU Usage
A high CPU usage is probably the most common cause of loud Macbook fans. So, you must check whether it applies in your case by going to the Activity Monitor section. Click on the CPU tab to view the percentage of resources each program is using.
Are there too many programs running on your Mac? If yes, then they can collectively use a lot of CPU even though their individual usage is quite low. Reducing CPU usage can help you reduce the sound of your MacBook fans.
Close Some Programs
Shutting down unnecessary programs is the best way to reduce CPU storage. You can do that from the Activity Monitor or go to each program and close them. Also, make sure that they do not keep running in the background. Now, this should make your Mac’s cooling fans quiet as they usually are.
Update the System
An outdated system can increase CPU usage on your Macbook in many cases. So, you must make sure that you have the latest macOS version. Go to the Software Update section to look for any updates whenever you are ready. Install any available updates as soon as possible before checking on the problem.
Restart Your Mac
Rebooting your Mac can also be quite effective in reducing its CPU usage. Turn the device off for some time or opt for a restart through its power options. This method might be ineffective if you have too many login items.
Disable Some Login Items
Login items are the apps and programs that start along with your Macbook. Enabling too many of them can take up a lot of CPU resources, resulting in loud cooling fans. So, you must also consider disabling some login items on your Mac.
Go to the System Preferences in your Apple menu and click on Users & Groups. Click on the lock icon at the bottom-left and select the Login Items option. Then, use the “-” button next to the programs and apps added there to disable them. Restart your Mac once you are done and check whether the fans are still loud.
Clear the Desktop
Do you have any unnecessary items on your Mac’s desktop? If yes, then they can contribute significantly to increasing CPU usage, and you must remove them. Delete as many of your desktop items as possible apart from the previous steps.
Free some RAM
Clearing the device memory can also help you fix the loud Macbook fans. You can delete all unnecessary apps, temporary files, system logs and browser extensions. The CleanMyMac X program can also help you clear some RAM on your device.

Clear the Vents and Clean the Fans
Your Macbook’s fans might work loudly because of blockages in the vents. Cleaning the vents will allow the fans to become quieter in such situations. In some cases, your Macbook might also have dirt and dust on its cooling fans. So, you might also need to clean the fans for an effective solution.
Cleaning the Vents
Your Macbook’s air vents might get clogged with dirt and dust as time passes, and you can clean them all by yourself. Using a can of compressed air would be the best way to proceed with this task. Make sure to clean up all the vents properly before checking on the cooling fans.
Cleaning the Cooling Fans
You must open up your Macbook to access the cooling fans and clean them. Reach out to a professional if you are unwilling to do that yourself. Otherwise, you must unscrew the screws at the bottom of your Macbook to remove the case. Clean up the inside of the case if you find it dirty before moving on to the fans.
Do you find dirt and debris on the fans? Use a brush or a can of compressed air to remove them effectively. You can also use a blow dryer for this task if you prefer. Attach the case back to the device with the screws once done. Then, check whether your Macbook has stopped working loudly.

Ensure a Cool Environment for Your Mac
Your Mac would overheat more easily in warm or hot environments. So, you must ensure that the room temperature is cool enough to prevent that. Take the necessary steps to provide your Mac with a cool environment if that is required.
Here are some of the things you must try out:
Remove Your Mac Away From Direct Sunlight
Exposure to direct sunlight can heat up your Mac more quickly than usual. So, you must always prevent direct sunlight from falling on the device. Keep it away from windows or other places that receive direct heat from the Sun.
Move it away from Other Gadgets or Appliances
Have you kept your Mac near another gadget or appliance? Then, it might receive heat from them and overheat more easily. You must move your Macbook away from all other appliances and gadgets in such situations. The fans can still work loudly after that, but they would surely do so much less frequently.
Use Your Air Conditioning
Check the room temperature at your home and consider turning on the AC if you have not already. Now, that can help your Mac stay cool much longer before its fans start working loudly. Alternatively, you can also move to another room if you find a lower temperature.
-
Ensure Proper Airflow for Your Mac
Your Macbook would need proper airflow to remain cool while working. Have you placed the device on a soft surface? If yes, that explains the fans working loudly as it blocks the airflow. Moving your Mac to a hard surface should make the fans quiet in a few minutes.
Placing your Macbook too close to other objects can also restrict the airflow significantly. So, you must avoid that mistake to prevent the cooling fans from getting loud. You can also consider getting a laptop stand for your Macbook to ensure its vents can disperse its heat.

Run Apple Diagnostics to Find Hardware Issues
The loud cooling fans on your Mac might also have something to do with hardware issues. You need not necessarily open up your Macbook to check on its hardware. Instead, you must use the Apple Diagnostic program to find hardware problems. The procedure for doing that differs depending on your Mac version.
On Intel Macs
Restart your Mac and hold down the D key to bring up language options for the diagnostic tool. Select a language to start the diagnosis and wait for your Mac to show the result. The next step you must take depends on what the hardware problem is if there is any.
On M1 Macs
Restart your Mac and hold down the power button until you see the startup options. Then release the power button and press Command and D simultaneously. This will launch the Apple Diagnostics on your M1 Mac, and you will get a diagnosis shortly.

Reset the System Management Controller (SMC)
The SMC controls various components of your Mac, and the loud cooling fans might indicate an issue. All you need to do is reset the SMC in such situations for an effective solution. The steps for doing that are usually the same on all the Macbook versions.
Press the left Shift, Control, Option keys and the power button simultaneously to reset the SMC. You must simultaneously release these keys and the button the same way you pressed them. Then, check whether the fan problem remains once you are done.
