Is your MacBook fan always on? Is it bothering you? Whenever you execute strenuous tasks or resource-consuming apps that cause your Mac to overheat, the fan on your Mac may turn on. Fan noise, especially on MacBooks, may make it sound like your laptop is trying to take off. Your Mac will, by the way, slow down if it becomes too hot. There are various safe solutions to minimize fan noise and cool down your Mac if your fan has been louder/active than usual, which we’ll discuss in this article.
The MacBook fan always on is typically not a sign of anything dangerous, and it can usually be fixed without too much trouble. Dust build-up, excessive GPU use, frequent wear and tear, and other factors can contribute to a MacBook fan always on issue. Tough, it’s important to note that your MacBook fan should always be turned on. If the fan isn’t spinning for a lengthy amount of time, the MacBook will shut down to prevent overheating damage.
Why is your ‘MacBook Fan Always On’ and How to Fix it?
Let’s go through various scenarios to help you locate or understand the MacBook fan always on issue.
1. Close Resource-Intensive Apps
Double-click, the Activity Monitor icon in Finder > Applications > Utilities to launch it. First, go to the CPU and see which programs consume most of the MacBook’s CPU. There’s also a GPU column to keep an eye on. After that, go to Memory, then Energy, and you’ll find a list of the most resource-intensive applications. Closing those apps should help minimize the amount of heat that the MacBook generates and, as a result, lessen the speed at which the fan spins.
To close the app, select an app from the Activity Monitor, click the X in the upper left, and then click Quit. As stated earlier, excessive GPU usage causes the MacBook to overheat. Thus you should first close the apps that use the most GPU.
2. Let the Air Circulate
We’re all tempted to use our Macs in bed now and then. It’s crucial to keep in mind, though, that duvets and soft pillows might have an impact on your Mac fan performance. Any soft surface you place your Mac on might block the air vents, causing the fan to spin faster and louder.
The easiest fix is to set your Mac on a flat surface, which will provide more air for the fan to operate with. Allow the Mac to cool down for a few minutes unless you need to continue working — which isn’t recommended because a Mac that overheats too much may shut down to protect hardware and data.
There are various Mac holders, and laptop stands for bed that you can buy for a more long-term solution; they lift a Mac off the surface and give a better view angle, which helps improve your posture and tackle multiple problems at once.
3. Check if your Cooling Fans are Functional
Your Mac’s air conditioning units/cooling fans may become problematic if it has been exposed to heat for an extended period. When the units fail to cool the laptop, it might cause your Mac to shut down abruptly. If your Mac has been overheating and you’re concerned about the fan, you may run Apple Diagnostics.
To use Apple Diagnostics on your Mac, open these instructions on any other device and follow the steps below:
- Remove all external devices except the keyboard, speakers, mouse, and monitor.
- Choose Restart from the Apple menu.
- As your Mac restarts, press and hold the D key. Continue to hold it down until a list of languages appears.
- Choose your language. Apple Diagnostics will run on its own.
4. Clear Up Space on your MacBook
Your CPU uses free hard drive space as fuel. When your hard disk becomes clogged, the CPU reaches its maximum capacity and begins to request some breathing room. Delete trash from your startup drive for the least intrusive way to solve a loud fan. You’ll be shocked how much space you can save without removing anything important.
In this scenario, a free version of CleanMyMac could be useful. It cleans up the system by removing trash files, old cache files, and failed downloads. Your computer should cool down and resume smooth functioning after giving it a breather and avoiding heavy apps from running when they aren’t needed.
5. Try Resetting SMC Settings
System Management Controller (SMC) is the driver that controls the hardware on your Mac, such as the fans, CPU, and motherboard. Restarting SMC settings is one possible fix for the MacBook fan always-on.
For Macs with non-removable batteries (which now account for the vast majority of Macs in use):
- Remove the plug from the outlet.
- Select Shut Down from the Apple menu bar.
- Press Shift-Control-Option on the left side of the keyboard to restart it after shutting down.
- Now hold down the power button for 10 seconds while pressing all four buttons simultaneously.
- To switch on again, release all keys and push the power button.
The approach is somewhat different for newer Macs with an Apple T2 Security Chip (2018 and later Macs):
- Shut down the pc.
- For 7 seconds, press and hold Control-Option-Shift.
- Then hit and hold the power button for another 7 seconds while holding all four keys.
- During the procedure, you have the option of turning it on and off.
- Wait a few seconds before releasing the keys and turning on your Mac.
6. Seek Expert Assistance
If any of the above ways didn’t resolve your MacBook fan always-on problem, seeking expert assistance is the last resort. Contact Mac apple support or customer service and convey the issue to the technical expert. They will look through the system and find the root of the problem, which will give you a smooth experience. After seeking professional help, your fan will work efficiently without any noise.
