Warning: We only recommend this if your Mac is slow, unresponsive, and is overheating. If your fans have been spinning for a while and your Mac is slow or unresponsive, you should check your running processes using Activity Monitor. This could be caused by a particularly resource-heavy process, or it could be a case of an app crashing. Sometimes, rogue processes end up consuming way too much CPU for an extended time period. Even remembering to quit a heavyweight app when you’re done with it can do wonders. Switching from a resource hog browser like Chrome back to Safari may help. Using lightweight alternatives to apps like Photoshop can certainly help, too. You can keep the heat down by avoiding processes that generate a high load, like rendering video or playing 3D games. As the heat builds up, the fans kick in to disperse the heat. The more you tax the CPU by running apps, copying files, and multitasking, the more heat is generated. The Central Processing uUnit (CPU) is the brain of your computer. You’ll need a spare USB port to use a cooler like this. The metal acts as a heatsink, helping to disperse heat through conduction while the fans provide active cooling. These take the form of metal stands with integrated fans. Laptop coolers (like this one from Thermaltake) can help cool down a MacBook that’s struggling in the heat. This could be a desk, or it could be a wooden tray or a large book on a bed. Sheets and clothing can easily interfere with air intakes, so it’s best to put your MacBook on a solid surface. If you are blocking these vents, your Mac will get hot even under regular load.īe careful when using your Mac on soft materials, like your lap or a bed. It exhausts hot air out of the back, behind the display hinge.

If your Mac can’t “breathe,” then it can’t cool down sufficiently either.įor example, the MacBook Pro sucks in cool air on the bottom of the machine near the right and left edges of the chassis. This is where your machine intakes and exhausts air, and these vents form a vital part of the cooling system. Pay close attention to the bottom and rear of your Mac laptop, if you have one. If you’re outside on a hot sunny day and you’re feeling warm, there’s a good chance your MacBook is, too. If the ambient temperature is hot enough, your Mac will reflect this by running the fans for longer and at higher speeds. You don’t necessarily need to be doing anything for your Mac to heat up. Make Sure Your Mac Can Cool Itself Properly

There are some things you can do to help reduce this happening. macOS will temporarily underclock your processor to reduce heat, a process known as thermal throttling. Ultimately, you shouldn’t need to worry about cooling your Mac manually (though there are things you can do to help). Generally speaking, around 90ºc (194✯) isn’t unusual for a Mac under heavy load, but you want to keep things below 95ºc (203✯). You can also use a small app like smcFanControl to place a widget in your menu bar that displays how hot your Mac is running inside the case. Loud rattling noises are also a red flag and usually occur when bearings in the cooling mechanism work their way loose. What isn’t normal is a hot silent Mac, which could suggest that fans have failed. Remember that heat is a normal part of your Mac’s operation, and loud whirring fans means the machine is operating as normal in an attempt to cool itself down. The computer should never be too hot to touch, though certain processes may make it uncomfortably warm, particularly if it’s a laptop that you are using on your lap. Under extreme load, it’s not unusual for your Mac to sound like it is about to take off. This means you will hear considerable fan noise when your machine is under load. While your Mac is hot, you should expect the fans to attempt to cool it down.

The most obvious is that the Mac feels hot to the touch, particularly on the underside of the chassis if you have a MacBook. There are several tell-tale signs that your Mac is running unusually hot.
