Your Mac’s fans probably aren’t something you think about very often—until something goes wrong. Maybe you hear the fan too often, and it’s driving you nuts. Maybe you’ve stopped hearing your fan altogether, even when you Mac feels hot. Either way, you should probably look into that.
For that, we recommend an app called. This free program lets you see the temperature of all your Mac’s components, and the speed of your fans in RPM (rotations per minute.) You can even adjust the fans manually, though it’s probably not a good idea to do this very often. Getting Start With Macs Fan Control To get started, head to the and grab the Mac version (There’s a Windows version, but is only intended for —other PC fans aren’t supported.) The download comes in a ZIP archive, which you can unarchive simply by opening it. Drag the application icon to your Applications folder, then fire it up. You’ll see a list of fans in the large left panel, and all of your temperature sensors on the right. The CPU will pretty much always be the warmest thing on your Mac, and the most important temperature to check—but it can be interesting to check the other sensors. For the most part, however, we’re interested in your fan’s current speed.
The minimum, current, and maximum speed are shown in that order. If you see high CPU temperatures—say, over 80 or 90 degrees—and that the fans aren’t running, you might have an issue. The same goes if you see a low CPU temperature—say, around 45—and the fans are running at full speed.
To find out if your fans are working at all, you can click the “Custom” speed button. Turn the fan up and see if you can hear anything. If not, your fan has some issues. I really do not recommend disabling the automatic fan control: leaving your fans on constantly will wear them out and waste energy, and leaving them off will overheat your Mac over time.
But for the occasional test, it’s nice to have control—just turn things back to automatic when you’re done. How to Troubleshoot Your Mac’s Fan Think your fan might be broken? The first thing you should do is launch Apple Diagnostics, one of the. Turn your computer off, then hold the “D” key while turning it on. Your Mac will test your hardware, and let you know if your fan is broken. If you have a broken fan, you need to replace it. My advice: head to the Apple Store or any authorized Apple repair shop.
I managed to replace my own broken fan on a 2011 MacBook Pro, but the internals inside more recent Macs are a great deal less friendly for home repair. It’s not impossible, however: check out ‘s guides if you want to attempt the repair yourself. But look at all the steps carefully, and only proceed if you’re completely confident you can get this done yourself.
If the hardware report says everything is fine with your fan, your issue is probably a software one. In these cases, often works—this is the low-level controller that manages thermal management and other things. If that doesn’t solve your issue, consider heading to an Apple Store, or another authorized repair shop. Passively Monitor Your Fan Speed If you want to impress your friends in conversation, you should keep track of your Mac’s fans and relay to them how fast they tend to spin during particular tasks.
I’m sure everyone will be fascinated at your next dinner party. To do this, open Mac Fan Control, then click the Preferences button in the bottom-left corner. Head to the Menubar Display tab, then select a fan and/or a sensor to display in the menu bar.
Click “Close”, and you’ll see the information in your menu bar at all times. Outside of amazing conversations, monitoring the fan speed passively like this can be helpful if you suspect there’s a problem.
It’s nothing I’d keep on constantly, but when things are acting funny it’s a nice tool to have around. Image credit.
One common problem Mac users experience is overheating. Not when a Mac is new, but when they get older and are full of files, images, videos and apps that slow down processing speeds, causing them to overheat. So if you’ve been working away and your Mac is hot to the touch.
Like hot enough to fry an egg? Don’t worry; this can be fixed.
Or what about when the fans are running so loud it sounds like a lawnmower? Again, both are signs that your Mac is overheating. An overheating Mac isn’t something you want to try and ignore for too long.
Apart from the fact the fans are noisy and distracting, and the hot temperature is irritating, your Mac could - probably will - crash and shut down. If you are working on something and haven't saved recently, you could lose important files. Worse than that, you could risk the Mac suffering irreparable file damage, potentially erasing files, systems and images you need and don't have backed-up. Why is my Mac overheating?
Unfortunately, there is no simple answer to this. It depends on how often your Mac overheats. Assuming this is a recent development, then it could be a sign of an overworked Mac. Too many files, taking up too much space on the hard drive, or too many systems, apps or browser tabs open at once. Especially if they’re heavy programs, consuming a lot of processing space and memory while you are running other apps, such as Spotify and have multiple browser tabs open. All of that activity can slow a Mac down and cause it to overheat.
So most people won’t need to see an expert; this is something that can be fixed at home or wherever your Mac is overheating. Remember, even MacBook Pro’s are relatively compact devices. Excess heat doesn't have many places to go, so when a Mac is overworked, it will start to get hot.
What you want to avoid is when it gets too hot, the fans get too loud and processes slow down. We’ve put together this guide to help stop a Mac overheating and avoid it in the future.
How to stop a Mac from overheating Firstly, you need to know what is causing the Mac to overheat. You can get for the job, a handy app that will quickly identify what’s absorbing so much CPU processing power. Close all of the apps running in the background and anything else that is using more computing power than looks wise. Unlike Activity Monitor, iStat Menus provides users with more data and insights,. You can get this from Setapp, along with hundreds of other apps for Mac customers, all for one convenient monthly price. Once you know what was causing it to overheat, you should be able to carry on working as normal.
If it happens again, you may need to look at over solutions. We have a couple in mind. The first thing to do is to declutter your Mac. Older Macs are going to be full of documents, apps, images, videos you don't need. Just like a house, when all of that clutter gets in the way, you can’t find what you do need. Your Mac struggles the same way, causing it to overheat. If while you’re tracking your Mac’s performance with iStat Menus you start noticing signs that gravitating towards overheating, try another app from Setapp collection, a cleaning software.
CleanMyMac comes highly recommended, as the easiest, most efficient way to identify problems, applications and settings that cause Macs to overheat, then clean them. Both apps are available on and you can use them for free for a week. When you’re running a drive cleanup, you might find that the files that take up the most space on your Mac are actually quite important to you. Large video files and huge image folders, 3D projects or movie renders, all kinds of important and increasingly megabite-hungry items.
Consider moving large files into the cloud. It’s a win-win because if they’re important, this way you won’t lose them and at the same time they won’t take up space on your Mac. Whichever cloud hosting provider you choose, there’s a really handy app to manage and share all your files from the cloud, it’s called. It feels like a native part of your macOS and works as a single platform for all cloud storage accounts that you have. Another way to reduce heavy CPU usage is to fix system issues or lighten up heavy apps. CleanMyMac X has a couple of tools for that. For instance, you can open its Maintenance tab and see Reindex Spotlight, Repair Disk Permissions, and Run Maintenance scripts.
Simply select these tasks and hit Run. After that, run a scan on System Junk and when it’s ready, find the apps with the largest cache (usually browsers and messengers) and clean up their cache. Important: depending on the app, you might lose histories and preferences, but if it’s the reason your Mac overheats, it’s worth it. Assuming shutting down browser tabs and apps, decluttering and cloud storing didn’t work; you need to look at any physical reasons for an overheating Mac. Check the following:.
Are you working on a flat surface? Macs more effectively displace heat when on a flat surface, not bed covers or other uneven surfaces. Are you outside in the sun? As tempting as it can be when it’s hot, working outside is one of the quickest and surest ways to experience an overheating Mac. In some cases, they will simply crash. Are your vents/fans covered?
Are you using any third-party devices to manipulate the fans? In either scenario, you risk overheating and need to unplug anything that could influence the fans. Are you in a dusty environment? Macs don't do well in dust. Once it gets in the fans, it could cause serious overheating problems. Assuming you’ve done/checked all of those options and your Mac is still struggling, it’s time to look at an alternative solution.
Your Mac could be too full of things that are slowing it down. How to keep a Mac from overheating To begin with, you need to define overheating and catch early it when it happens. To monitor the temperature of your Mac, use that we mentioned earlier. It looks into your system and gives you timely updates on CPU temperature, which is a key indicator you need to prevent overheating. Then, you can get timely notifications from iStat Menus when your Mac is near dangerous temperature.
This will help you mitigate potential damage or data loss and tone down CPU usage before anything crashes. That’s about it on the subject of Mac getting hotter than it should. We hope this guide has been of help and if you want to make sure your favorite computer stays cool, get iStat Menus with monitors and CleanMyMac with maintenance tools in, that should cover your needs. In case after both fixes and manual troubleshooting, your Mac is still overheating, you might need to book in with a Mac specialist. More extensive problems may require a trip to a certified Mac Consultants Network retailer, or Mac support from your nearest Apple Genius Bar. Apple Support can also offer help online or over the phone - you just need to book an appointment first.
