If the fans are not just loud, but they’re also making funny noises, there is a chance that there can be something wrong with the fans physically. To check if this may be the case, follow the steps below. Your MacBook’s built-in diagnostic features will tell you if any block is malfunctioning.

How to stop MacBook Pro fan noise

Macs are pretty quiet gadgets. So when your MacBook starts making noises like it’s on a ventilator, it can spook the owner. Fret not. It just means that the cooling system kicked in for maintenance. However, if it happens too often or the fan on your laptop won’t turn off at all, go for these tried-and-true methods.

Reduce the temperature

The most common reason why your MacBook Pro fan is making noise is overheating. The processor temperature can be affected by the way you work with your laptop. Do you like to curl up on a sofa and prop your Mac on a pile of pillows? Maybe you watch Netflix in bed, leaving your laptop on a fuzzy blanket? The thermostat or direct sunlight also can be the factors.

Double-check the airflow

For the best performance, use a bed table or lap stand to ensure you’re not blocking the airflow around laptop vents. On the MacBook Pro, the vents are placed on the sides and on the back of it. Examine them closely and if you discover any grim, blow it out with pressured air or ask your service for a deep clean.

Reduce consumed processing power

The rule of thumb with MacBook Pro is to keep the applications shut down when they’re not active. This is especially important if you’re working with heavy apps like Final Cut, Photoshop, Maya, and likes. You can also ease life up for your laptop by simply running smaller apps, like Spotify, from your phone.

How to deactivate fluff apps that eat up your processing capacity? To do this in the MacBook Pro, go to Activity Monitor:

  1. Open Activity Monitor (Applications — Utilities — Activity Monitor)
  2. Look for the CPU tab. On top of the list, you will see the most heavy-on-resource apps
  3. Pick the tasks and hit the X to shut them down

Free up some memory

The free memory is crucial for the laptop to keep up the fast work. Clean up your junk folders to give your Mac all the play space it needs for the best performance. For an extra deep clean, opt for the defragmenting applications that will comb out all broken files and unused duplicates.

Test the cooling fan’s hardware

Being exposed to heat or to mechanical damage can affect the physical condition of the fans. If you suspect that this might be the case, it is easy to double-check with the MacBook’s built-in Apple Diagnostics.

To run the Apple Diagnostics:

  1. Strip your laptop off all external devices
  2. Go to the Apple menu and click Restart
  3. As the Mac reboots press and holds the D key. Keep holding it until a list of languages drops out
  4. Pick your language. The Apple Diagnostics will run automatically and get back to you with a result

Reset SMC settings

SMC, or System Management Controller, is an extra control station put into your laptop by Apple. This driver is responsible for the hardware such as – you guessed it – fans, also motherboard, and processor. Reset the SMC settings to see if this will help to rewire the fans and reduce the noise. To reset SMC on your computer, go this route:

  1. Unplug the power cord
  2. Click Apple menu — Shut down
  3. The computer is shut down, hold the Shift+Control+Option on the left of the keyboard
  4. Now press the power button and keep the four buttons pressed for 10 seconds.
  5. Release the buttons and turn on the computer

The procedure is slightly different for the Macs with the T2 security chips. These include all Mac laptops made in 2018 and later. So, if this is the case, after turning your computer off:

  1. Press and hold Shift+Option+Control for 7 seconds
  2. Now press the Power button and hold all four keys for 7 more seconds
  3. Let go, wait for a little, and start your Mac again

The fan on your Mac still won’t turn off?

If the problem persists despite all your efforts, and the check of the hardware setup didn’t give you the desired result, this may be a more serious hardware malfunction. In this case, visiting your nearest certified Apple service provider will be the right thing to do.
