How to Fix MacBook Pro Fan so Loud?

White noise doesn’t usually bother us… unless you’re trying to get things done when it comes to spinning old MacBook fans. It often seems that these are triggered for no reason and they can become annoying very quickly. So how do you determine what’s getting your fans into the action? In this guide, we’ll show you how to identify why your old MacBook Pro Fan so Loud Pro fans are loud and how you can bring them back to normal.

Possible Reason 1: Poor venting/circulation

This is one of the simplest of loud fan causes and also the easiest to check, fix, and resolve. Here’s the explanation: Your Mac heats up because the electrical process needed to use it releases energy. The fans inside are designed to cool it, but they have to work overtime when there is no normal airflow around the laptop.

If you’re working with your MacBook flat on your lap or desk, you’re effectively preventing any air from circulating under your laptop and making fans work twice as hard to cool the component. are forcing.

How to Fix it:

If you just need a short-term fix, hooking up your MacBook and leaving it idle for a few minutes before going back to work will help narrow down the problem.

But if that’s a consistent issue for you, consider investing in a high-quality laptop stand to lift your MacBook and allow for better air circulation. You can check out the best stands for the MacBook Pro that we recommend, all of which will help tone down the fans and make your Mac more comfortable to use. Also, consider using a cooling pad if the laptop constantly heats up.

You may also consider cleaning the vents and making sure there is no dust around. Do this with caution as you will need to open the bottom case and vents. Once you clear the air tunnels, it can make a big difference.

Possible Reason 2: Running heavy apps

Because fans are used to cool internal electronic components, forcing these components to work overtime will also put the fans into high gear. This results in annoying whistling noises that you want to get rid of.

Web browsing and document editing are simple everyday tasks that will not contribute to this problem. However, if you’re using heavily creative software like Adobe Creative Suite, photo, and video editing applications, or graphics-intensive games, you’re trying to keep your fans in a frenzy.

How to Fix:

If you must run heavy programs, take all possible steps to reduce the load on your computer.

  • Run only those programs you need at a time and don’t leave others idle in the background.
  • Decrease the frame rate or processing speed as needed.
  • Make sure you are already taking all possible steps to optimize your Mac such as using it in a temperatur0e-controlled room instead of outside on an already hot day, etc.

If this is a regular problem and you can’t reduce the workload, you may need to consider upgrading your Mac to buy more RAM or if you can get a newer MacBook specifically for video editing. If so, it can meet your demands.

Possible Cause 3: Hidden CPU Drains

So you’re not using any heavy programs but suddenly the fan is acting up?

Especially if you recently updated, changed some settings, or installed a new program, you may be experiencing some hidden background tasks that are eating up your CPU.

The easiest way to check if this is happening is to go to Spotlight (with a search icon) in the top right corner of your screen and type “activity monitor”. Once Activity Monitor is open, navigate to the CPU tab and look for programs that may be using a very large percentage of available power. If you find one, you know what your culprit is.

Keep in mind that if it’s a program and not a background task (apps have recognizable names and icons, background tasks look a bit more obscure), you should check #2 instead.

How to Fix:

As you can see in my screenshot, I’m currently experiencing no problems and all usage (highlighted in red) is pretty low. But once you’ve identified the tasks that are using an inappropriate amount of CPU, click on it in Activity Monitor.

It will be highlighted in blue, and you will be able to click on the X button in the top left corner which will quit the process. Wait a few minutes for the fans to turn off and on to test how quitting the process affects your machine.

Pro Tip: Make sure you save everything you’re working on before you force quit a task from Activity Monitor.

If the task later reopens or comes back, it can be built into a specific program. In that case, you’ll have to research the program it’s part of and see which setting is to blame.

Possible Cause 4: Fans in need of repair

Have you been using your Mac in dusty or dirty places lately? Perhaps you had to take it out of the office to a workplace or take it with you on vacation.

If you’ve been in a less than ideal environment recently, or simply over time, lint, dust, and other air contaminants can build up on your fans.

How to Fix:

There are two ways to clean the dust off your Mac’s fans. The easiest way is to use a can of compressed air to push air through the vents on the back of your laptop. Be careful not to hold the can too close and apply unnecessary pressure, which will potentially damage the components inside.

If compressed air doesn’t work from the outside, you can also open the body of your MacBook to clean out the fans. This is not recommended unless you are sure you know what you are doing.

First, search for your MacBook’s model on iFixit to get instructions on how to open the body for your particular Mac. Then use compressed air to gently blow the particles out of your Mac. Do not use a vacuum under any circumstances, as static can ruin electronic components.

Also, you may need to replace your MacBook’s fan for better performance. First, get a left and right-side CPU cooling fan from Amazon, then go to iFixit, find your MacBook model and find the right guide. If all else fails, take your MacBook Pro to a nearby Apple Genius Bar to have it serviced and professionally cleaned.
