Why is my Macbook Fan So Loud? Reasons and Solutions

09.16.2022

What should you do if the laptop fan is making a lot of noise? In this guide, we are here with the laptop high fan noise problem and solution that many people experience!

Today, we see that laptops still have a significant market share. As a matter of fact, the inability to carry desktop computers and the fact that tablets still cannot reach the level of computers are among the biggest reasons for this situation. But what can you do if this device that you can carry anywhere makes sounds like it is getting ready for flight from time to time?

How To Fix Laptop Loud Fan Noise Problem?

From a basic point of view, the fact that the computer runs the fans indicates that the ambient temperature should decrease. If your device is overheating, what you need to do is to lower the temperature. To be able to do this comes down to finding the main source of heat at some point.

1. Make sure the vents on your Mac aren’t obstructed

Your Mac’s fans operate by drawing in fresh air and expelling warm air. Your Mac will continue to get hotter if any of the vents are blocked, and the fans will continue to run faster to cool it down.

When customers rest their MacBooks on soft surfaces, like mattresses or pillows, this frequently occurs. Try transferring your MacBook to a firm surface, such as a table or desk, if it is operating noisily.

You should also check the vents on all different kinds of Macs to make sure they aren’t blocked with anything. If so, clear them out with a brush.

2. Ensure That the Vents are Clear

Never missing an opportunity, dust, dirt, and grime find their way into even the smallest ports and vents. There’s a significant likelihood that dust is obstructing airflow if you haven’t cleaned the vents in a while. Remove the bottom panel of your MacBook with a screwdriver, and then use compressed air to try to blow any material away. To clean the vents, you can also use a soft, lint-free cloth.

3. Close the Apps You Are Not Using

Programs open on your computer are constantly running and occupy both the processor, memory and disks. This means more processing power is required, and you will encounter some heat during the creation of more power. The first thing you should do is close the apps and programs you are not using.

However, it is not limited to this because you may think that you have closed everything. Now look at the dock part and find unnecessary applications that are running in the background. After closing them, view the programs that open at startup from the settings, close the ones you don't need. This will cause less processing power to be consumed the next time you turn on your computer.

4. End any processes using a lot of CPU

The processor in your Mac will get hot when it is working hard. It will become hotter the more work it has to accomplish. By turning off whatever is causing your CPU to work so hard, you can stop your Mac’s loud fan noise using the Activity Monitor program.

Using the macOS Activity Monitor, stop processes:

1. Open Activity Monitor by selecting Applications >> Utilities.

2. To sort by highest first, click the top of the percentage CPU column in the CPU tab.

3. Select the item in question and press the X button if it is consuming too much CPU time.

4. To end the process, click Quit.

5. Lower the surrounding temperature

Although it may seem simple, your Mac will also be hot if the atmosphere is warm. That might be sufficient to get it to turn on its fans and produce noise.

The solution is rather easy: reduce the room’s temperature by opening a window or turning down the heating. Another option for cooling down your Mac is to direct a desk fan at it.

6. Inspect your hardware for issues

Sometimes defective parts can generate a lot of heat. But that’s not the only hardware issue that could arise because Macs have a number of internal heat sensors that control whether the fans spin more quickly. The fans on your Mac may run louder and quicker if these sensors malfunction.

You might be able to identify the problem’s root cause by using the built-in Apple Diagnostics tool in macOS. There are no assurances that this will succeed, though.

7. Reset your SMC

By clearing the System Management Controller (SMC) on Macs, you can solve a variety of issues. The power supply, lighting, and of course the fans are all controlled by this on your Mac. Depending on the model of your Mac, there are various ways to reset the SMC.

To reset your SMC on an Intel desktop manufactured in 2018 and later, follow these steps:

  • Unplug the power cord after turning off your Mac;

  • Reconnect the power cord after 15 seconds;

  • Then, after a further 5 seconds, restart your Mac;

Check Apple’s published instructions for information on other Mac models.

8. Perform a Software Clean

Although Apple protects their computers like a sealed box, they can often be exposed to malware. Some of these types of software run in the background and tire your device. You can think of this in a similar way to the above article, but the solution is different.

9. Do Physical Cleaning

At this point, you will need to get help from an antivirus program. After installing the antivirus application, do not forget to run it and scan frequently. In addition, every antivirus software is updated in short periods, usually once a week, and incorporates new anti-malware measures. Therefore, do not miss the updates.

If the laptop you're using can't get enough airflow, it will heat up, causing the fan to spin much, much harder than it should. Basically, all of this means a fan that is running loudly, so physical cleanliness is important.

10. Get a Cooler

If that wasn't enough on its own, or if you have an older computer, you may want to consider using an external cooler as a tertiary aid. This means you can't use your computer on your lap, but that's not healthy anyway. In this way, the external cooler will solve the heat problem that your fan cannot handle. If you're going to buy a cooler to get rid of the fan noise, make sure you choose something that runs quietly. Otherwise, as you've noticed, it won't make much sense.

10. Use Only Apple-Approved Power Adapters 

Partially at fault for overheating problems and causing the fans to turn on earlier are non-certified power adapters with less effective thermals. Therefore, be sure to use only Apple-Approved power adapters.

What to Do if the Fans on Your Mac still Won’t Stop Running

Your Mac may have a more significant issue if it is overheating or if the fans are running loudly even when it is cold. That can be a hardware or software issue. There isn’t much you can do if the hardware is broken other than try to have it fixed. You can probably get assistance from Apple support or a reputable repair service.

FAQ

What will happen if the fans on my Mac stop functioning?

Your Mac will just continue to heat up if your fans stop functioning altogether. It will eventually turn off by itself to prevent components from being seriously harmed. If the vents on your Mac are obstructed, this may also take place.

Can I manually regulate the fans on my Mac?

No, by default. Your Mac will turn the fans as quickly as it feels is necessary to keep it cool. However, you can download software that enables manual fan control for your Mac. This can be helpful if you know what you’re doing, but it’s also unsafe, which is why we aren’t here promoting any fan control options.

What level of heat is normal?

Macs can produce a lot of heat while still running securely. For instance, Apple claims that a MacBook operates normally between 50ºC and 95ºC. Therefore, if your Mac feels warm to the touch while in use, don't worry.
