Popular solutions to Mac fan noise
There are a number of solutions for a loud Mac cooling fan, and you should be able to get it under control fairly soon.
1. Improve air circulation
Inside a Mac, where there is a lot of processing power — if not moving parts (as there aren't many of them in modern Macs, MacBook Pros and Airs) — and the more you use it, and harder it’s working, the more air is needed to cool it down.
The fan is designed to keep internal processes and systems cool, so that a Mac keeps working. But like any fan, it needs air and good circulation to make it work.
So the quickest solution is to prop the Mac up, give the fan more air to work with. Unless you need to keep working — which isn’t advisable as a Mac that overheats too much could switch off, to persevere hardware and data - give the Mac a few minutes to cool down. Not unlike an athlete: It will be working again soon, it just needs time to rest before you can get started again.
For a more long-term fix, there are countless Mac and laptop holders you can buy; they elevate a Mac off the surface of a desk and improve posture and how a Mac users views a screen with it being elevated, solving several problems at once.
2. Free up memory and processing power
Another solution, also one that is a useful short and long-term fix, is to find out what is using processing power, then either switch apps off or delete them if they're not needed.
To find out what is taking up processing power, the first place to look is Activity Monitor.
- Go to Applications;
- Click on Utilities > Activity Monitor;
- Activity Monitor will show what is taking up CPU and GPU;
- Giving you the ability to close anything that is clearly taking up too much battery power.
3. Disable heavy memory consumers
If there are apps you don't need using too much power and therefore making your Mac overheat, the best way to remove them is to use a Mac maintenance tool, CleanMyMac X. This application is notarized by Apple.
- Download CleanMyMac X (download a free version here)
- Click on the Speed tab;
Within this, you can switch off or remove for good: Login items, Launch agents and various add-ons.
Make sure to check the Heavy Consumers feature. It will show you the apps that heavily drain your CPU and thus overburden the fan.

In this post,we’ll show you some of the ways you can get your laptop fan working likenormal.
A noisy fan meansyour laptop is being pushed to its limits. Usually by a program that’s taxingon your onboard RAM.
That or maybe thefan just needs some attention.
Unlike desktopfans, which have more room to breathe, laptop fans are smaller. So they have tomake up for it by blowing harder.
Whatever the casemay be, rest assured that there are ways to remedy the situation.
LiftUp Your Laptop
Let’s start withsomething basic. Elevating your laptop will give it room to circulate air muchmore efficiently. This leaves your fan more room to work with.
Because mostlaptops have fans facing the bottom, the exhaust panels are partially blocked.This makes it hard for hot air to blow out.
So raise yourlaptops up, give it room to breathe, and the noise should go away shortly.
DustUp the Fans
If the first tipdoesn’t do it, then the fans might need some cleaning.
Dust buildup isnothing new when it comes to overheating laptops. Unfortunately, laptops arebarely maintained, if at all.
So if aconsiderable amount of noise is being produced, it’s possible the fan bladesare blocked.
Grab somecompressed air and blow some air right into the fans. Of course, it would bebetter if you can remove the back panel. This would ensure that the dust isblown out of the laptop and you’re not driving dust further into the unit.
While you’re atit, consider cleaning the other internal components.
Note: Not all laptop parts canbe removed. So don’t forcibly remove these sections.
After the dust isremoved, put the laptop back together and see if the fans are still making anynoise.
PlugIn a Laptop Cooler
Laptop fans coulduse a little help from external cooling fan solutions like those sold onAmazon.
These gadgetsprovide additional air circulation that alleviates some of the pressure put onbuilt-in laptop fans.
They’reinexpensive and detachable so you don’t have to carry them around when youdon’t want to.
It’s normal forfans to run as soon as it’s booted up. But when fans throttle at full speedbringing it to its limit, you may have a problem.
Here are a fewsteps you could take.
The averageperson would normally run two or three programs at a given time. And for themost part, that’s fine.
But it’s not thecase for power users. They would often run web browsers, MS Officeapplications, photo or video editing software, and stream media content on topof it.
This causes fansto work extra harder to dissipate all the heat the computer’s creating.
Some laptops arenot designed to handle a heavy workload. So it’s better to shut down someapplications so your fans don’t throttle as much.
You can useWindows Task Manager to determine which programs are draining your RAM and CPU.
Neither are necessary for detecting and removing malware, however, so pay attention during installation if you don’t want them.If privacy is particularly important to you, you may want to keep in mind that Avast does collect and sell its customers’ web browsing data.

To open TaskManager, right-click on the Start iconand select Task Manager from thelist of programs.
But what ifyou’re barely running applications? Why would your fans run at full strength?

If you suspectthat your laptop has been infected, you need to run your antivirus program. Ifyou don’t have one, there are a lot of free software online that you coulddownload and install.
You can also useTask Manager to find programs that are running in the background. If there areunfamiliar programs in the background, you can force these tasks to stoprunning.
