Are the fans on your MacBook moving air? You might be concerned. MacBook overheating Yours. Or the noise could be getting on your nerves. Or both. Either way, there are some simple solutions you can adopt to address this issue. When you render a 4D file, watch XNUMXK content, or crunch some serious numbers on your Mac, the system generates a significant amount of heat to handle all these tasks. So, the fans inside your MacBook (models with a fan inside) run to reduce the internal temperature to avoid overheating. However, some serious issues can cause your MacBook fans to stay on all the time. If this is an issue you're experiencing, here are the best ways to fix Apple MacBook fans that always stay on.
1. Close unused background tasks
The more apps running in the background, the hotter your MacBook gets. Naturally, the hotter your MacBook gets, the more its fans run. This is especially true if high-intensity apps are running in the background.
To prevent fans from running all the time, close any background apps you may not be using on your Mac. This applies to any additional tabs you have open in Chrome but never visit.
2. Check CPU usage and terminate resource-intensive tasks.
You can run different tasks on your MacBook, depending on your workflow. This might include smaller applications like browsers or high-intensity applications like video editors or audio mixers. If you're a power user, you might run several of these applications but not use them at the same time.
This means that CPU usage will naturally be high. You can use Activity Monitor to check which programs are consuming a lot of resources and terminate those tasks if you're not actively using them. Here's how to check the resource consumption details.
Step 1: Click on Command key and space bar at the same time on Mac to show Spotlight Search.
Step 2: Type Activity Monitor Click on the first result that appears.
Step 4: Look for Applications High number under %CPU columnIf you do not use any of these Applications Click on it and then press Stop button above.
You'll need to repeat the same process for all CPU-intensive applications, and stop using them. This will help reduce power consumption and heat generation for the internal fans.
3. Do not block the ventilation holes on your MAC.
Your MacBook has vents near its hinge. These vents are used to expel hot air from your Mac. If you block these vents, your MacBook will almost certainly overheat. Now the question is, what are the conditions that can cause the vents to become clogged?
If you keep your phone or anything else on the hinge, resting on the display, it blocks the vents. This can also happen when placing your Mac on a soft surface like a bed or pillow. Avoid such practices and ensure that the vents remain unblocked while using your Mac.
4. Remove any wrapper if using one.
The MacBook's aluminum enclosure helps dissipate the heat built into the Mac internally. Fans blow hot air from the components out through vents at the hinges between the body and display.
Using a thick case on your MacBook can trap heat, especially if the keyboard and vents are covered. This results in your MacBook overheating and the fans tend to run continuously. Therefore, try using your MacBook without a case or cover and see if this helps improve airflow.
5. Ensure a cool ambient working temperature.
You won't be able to work with concentration in unbearable heat. Similarly, your Mac also needs a certain operating temperature to perform well. Furthermore, if you work in a cool room or environment, this will help you keep your MacBook's heat levels at bay.
Likewise, your MacBook performs best in a cool environment. When exposed to heat, your Mac will use its fans at full spin to cool the internal components. Therefore, your best bet is to use your Mac in a cool, dry environment.
6. Update to the latest version of MACOS devices.
If you've been delaying any macOS updates, the older version may not be as efficient at handling all modern tasks with ease. Upgrading to the latest version of macOS can bring many new features and also fix any underlying issues. Here's how to update macOS.
Step 1: Click Apple logo At the top left of your screen.
Step 2: Locate About This Mac option.
Step 3: You will now see a pop-up window with details. About Mac Yours. Click on upgrade software.
Step 4: Wait while your Mac searches for Last updatedIf an update is available, it will be displayed.
Step 5: Click “Update now” And wait for the process to complete.
Wait for the update to install and restart your Mac.
7. Reset the PRAM on your MAC
PRAM (Parameter RAM) stores important data about your Mac, such as the default values for the startup disk, virtual memory, and even some hardware components. Resetting the PRAM can help restore the fans to their default state if none of the above solutions work. See our guide on how to reset the PRAM on your MacBook.
Note that our guide only works on Intel-based MacBooks and not on newer M1 MacBook models. This is because newer M1 devices operate differently.
Stop the noise
Despite using our tricks, if you're still struggling with the fans on your MacBook continuing to run all the time, it's best to get your hands dirty by unscrewing the back of your Mac andCleaning fans yourselfOf course, this requires some knowledge of handling components, so if you're not comfortable doing it, you can always take your MacBook to an Apple-authorized service center.
