The MacBook Pro is a powerful yet portable device. The unibody chassis is milled from a block of Aluminium and this makes it light, thin, and sturdy. However, all that power from the Intel CPUs can make it run hot and that can make the fan run at high speeds. This is completely normal during workloads, but if you are hearing loud fan noise constantly, then this might be because of an underlying issue. If you are annoyed by the MacBook Pro fan noise, then you are reading the right article.
Today, I am going to go over the reasons for the loud MacBook Pro fan noise and what you can do to reduce it. I am also going to help you prevent this in the future. Let’s get started.
Why Does my Macbook Pro Fan Make Noise?
Fans usually ramp up whenever the CPU is running too hot. The fans do this to cool the processor and they make sure that the heat does not do any permanent damage. If the vents of your MacBook Pro are clogged by dirt, then the fans won’t be able to draw enough air from outside. The CPU won’t cool off properly and this will make the fans spin even faster and make them noisier.
The temperature outside can also affect the fans of the MacBook Pro. Fan noises can also increase if you turn on and plug the MacBook charger at the same time. Constantly loud fan noises can be worrying especially when you are not running any intensive programs. However, the fixes to this problem are easy.
Note that loud fan noise is fine if you only notice it while running heavy programs or playing games.
How to Fix MacBook Pro Fan Noise?
I have compiled a list of solutions for this problem. I recommend you try them out one by one. Before you start, you need to close every application.
1. Check the Vents
The MacBook Pro has vents along the side and on the back. Make sure that there’s nothing blocking the vents. The vents can also be covered if you keep your laptop on a soft surface like a bed. Try moving it to a table or desk and see if the loud noise persists.
If it’s an older MacBook Pro, then you are going to have to open it up and clean it from the inside. Check out this video for that:
2. Move to a Cooler Room
As I mentioned earlier, ambient temperature can affect the CPU temperature. The fans are going to get louder if your CPU is running too hot. Try moving the MacBook Pro to a cooler place.
3. Check the Background Apps
Apps that are running in the background can hog up a lot of CPU power and make the fans run louder. In some cases, a program can run into errors and the CPU will try too hard to solve it, making the temperature rise up. You can use the Activity monitor to check if any program is malfunctioning or using too many resources.
- Click on the search icon at the top right corner to launch Spotlight.
- Search for Activity Monitor and run the app.
- Make sure you are on the CPU tab.
- Choose View > All Processes.
- Now click on the %CPU column heading to sort the processes based on used CPU power.
- Since you are not running anything, the percentage should be small. However, if you see an app (except kernel_task) that is using a lot of CPU power, then you should click on the process and then click on the x icon at the top left corner to force quit.
4. Reset the SMC
Apple introduced the T2 security chip in the 2018 and later versions of the MacBook Pro. This chip was added to increase the security of the MacBook Pro, but it created a new bug. Your fans will run at high speeds if you press the power button while plugging in the charging cable and this issue will not be fixed with a restart. But don’t be alarmed as this problem can go away as soon as you reset the SMC. to do that, follow the steps below:
- Turn off your MacBook Pro.
- After it turns off, press and hold Option + Control + Shift keys for 7 seconds.
- After 7 seconds, press and hold the power button but do not let go of the other keys.
- Release all four keys after another 7 seconds.
- Wait for a minute and then turn the computer back on.
Your MacBook Pro’s fan noise should be under control now.
These steps will help you reduce the MacBook fan noise. If it’s still causing you problems, then it’s probably a hardware issue and you should get it checked out at a Genius Bar.
