Why is My MacBook Making a Fan Noise? 6 Ways to Solve it!

We’ve been asked a lot of times the same question over again by Mac users, “Why is My MacBook Making a Fan Noise?“.

Well, If your MacBook’s fan is running too loud for too long, or too often, you might have a problem with your laptop. For the most part, fans are an essential part of your laptop.  Humans sweat, dogs pant, and laptops usually have fans to keep them cool. Your MacBook Pro or MacBook Air will sometimes automatically start up its cooling fan to keep its temperature in check.  However, if your Mac’s fan has gone from spinning only sometimes to spinning all the time and making a lot of noise, then you’ll have to slow it down.

Most of the time, Macs are considered quiet laptops. Though, your Mac fan can start making a lot of noise out of the blue, which can be annoying if there’s no clear reason for it. Consequently, you will need to find a reason why your MacBook fan has become so loud all of a sudden.

If your laptop’s processor is doing a lot of intensive work, like compressing high-definition video, playing a game with a lot of graphics, or indexing the hard drive with Spotlight after you move data, the fans run faster to provide additional air to the laptop. Then, you might hear fan noise especially if you’re in a quiet place. This sound of rushing air is a part of the cooling process but it can get annoying.

Also, the outside temperature affects the speed of the fans of the Macbook. Specifically, in hot weather, the fans start running more quickly. Well, we have listed some of the techniques which can help you to solve the Macbook’s fan problem.

How to Check my Mac’s CPU Temperature?

In the case, if constant heat is coming out of your MacBook Pro or Air then it may be a clear indication of overheating. So, you must check your Mac’s temperature. There are a number of temperature monitoring software to check Mac’s CPU temperature.

In our opinion, you can download iStat Menus or TG Pro, as they allow you to observe the temperature inside your MacBook. The normal temperature of Mac’s CPU is around 90 degrees Celsius.

6 Ways to Solve Macbook’s Fan Noise Problem

1) Check your apps and tabs

In general, the more apps and browser tabs you run, the more likely your Mac will need to use its fan to keep things cool. When you’re done with an app, close it. This is especially important if you’re using a graphics-heavy app like Photoshop or iMovie.

If you want to see which apps are taking up the most CPU power, open the Activity Monitor and click on the CPU tab. Google Chrome is a bigger drainer of resources than Safari, so you might want to switch browsers for a quieter Web experience.

2) Keeping the vents Clear

Sometimes, we all want to use our Macs in bed. But, you should keep in mind that duvets and soft pillows can change the behavior of your Mac fans. Covering the air vents on your Mac with any soft surface can make it run faster and sound more.

If you put your Mac on a flat surface, you’ll give the fan more air to work with. If you don’t need to keep working, let the Mac cool down for a few minutes. A Mac that gets too hot while carrying out any intensive task could shut down to protect its hardware and data.

For a more long-term solution, there are a lot of Mac holders and laptop stands for the bed that you can buy. They raise a Mac off the surface and give a better view angle, which improves ventilation your posture at the same time.

3) Open up and clean

Remove the bottom of your MacBook with a screwdriver to clean out any dirt, dust, and sludge that has built up over the years.   Make sure the lint-free cloth you use isn’t dirty while cleaning your Macbook. Moreover, closely examine your MacBook’s cooling fan and all of its vents and make sure there are no obstructions in the way of airflow.

4) Check for Hidden CPU Drains

Even if you haven’t been using a lot of apps or programs, but your fans have suddenly started to make a noise, then there might be some background tasks that are eating up your CPU’s power.

To check it, go to Spotlight and type Activity Monitor to see if this is true. After that, click on the CPU tab and look for apps that use a lot of power. If you find any, you need to close them right away and it may solve your issue.

5) Test your fans

There is a chance that the reason your MacBook is overheating is that there is something wrong with the fan itself. There is a pre-installed tool in your Mac that can check your computer’s hardware. If your Macbook was made before June 2013, use the Apple Hardware Test. However, if it’s manufactured after that date, you’ll use Apple Diagnostics.

These tools work in a similar way. As soon as your MacBook is turned on, hold down the D key to start either of these diagnostic programs.

Start the test by following the instructions on the screen. The standard test only takes a minute or two to run, and it will tell you if there are any problems with the hardware. For a more thorough examination, you can check a box to run an extended test that may take an hour or more to complete.

There are some codes that may show up in the Test Results section after the test is done.  There are three codes that start with “PPF,” and they all are related to the cooling fan. Consequently, it’s time to call Apple Support or go to your nearest Genius Bar to get your fan fixed if you get one of the results that say there might be a problem with your cooling fan.

6) Reset the SMC:

If your Mac is clean and free of dirt and grime, but the fan is still spinning and making a lot of noise, then you might want to try resetting the System Management Controller (SMC). The SMC is in charge of a lot of low-level things on your Mac, like “thermal management,” or the fan that cools it down.

In order to reset the SMC on your Mac, follow the below-mentioned steps:

  1. First of all, shut down your Macbook.
  2. Afterward, press and hold the Control-Option-Shift keys for 7 seconds.
  3. Then press the power button and hold all four keys for another 7 seconds. Your Macbook may turn on and off during this process.
  4. Finally, release the keys, wait a few seconds, and then turn on your Mac again. It can surely solve your issue.
