SMC Fan Control is an application that allows you to monitor the temperature of your Mac and adjust the fan speeds accordingly. However, even if you want to stick around for some good reading, carry on! All modern Macs have several internal temperature gauges, however, the ability to see those temperature readings is not built into the OS. To do this download SMC Fan Control or iStat Menus below.ĭo note that this article is for the Macbooks modelled before 2016. If you are confident that your MacBook is overheating you can download an application that allows you to see your Mac's internal temperatures. If you're interested in our reviews and ratings of each one, check out our overview below or click here for the full article. We've added a comprehensive breakdown of our favorite laptop cooling pads. This is the ultimate guide to preventing your Mac from overheating! If a MacBook is genuinely overheating, the cause could be a number of things, most of which are easy to fix, but unfortunately are often left untreated. To find out how to diagnose and solve your MacBook's overheating problems, not only ensuring your MacBook a long life but protecting your body from potentially harmful heat radiation, read the rest of this article.

However it is often difficult to differentiate between a MacBook that is simply running hot, which they are designed to do, and one that is genuinely overheating. You can base the fan speeds on other internal temperature sensors like the CPU.WARNING: An overheating MacBook could be the sign of a virus or malware infection. I have set up fan rules that set the fan speed to 3000RPM if the battery temperature is above 35C when the battery is charging, or 5500RPM if the battery temp is over 40C at any time. Some use Macs Fan Control, but iStat Menus has that built in and I already have that. The other thing you can do is control your internal fan speeds manually. MacBook Pros have long had primary ventilation out the rear vents. I believe that Apple has probably done thermal management testing with the lid closed. I do not think Apple would have a whole tech note telling us how to use closed clamshell mode if it was dangerous for the screen. I won't have to plug the fan into the Mac, when it gets here it will be powered by my USB hub. I have found that this lowers the internal temperature a lot more than leaving the lid open. To allay my concern I ordered a quiet little USB powered fan to put next to the MBP, to blow air horizontally over and under the closed case. My 2011 maintained its battery life so well (80% after 5 years) that I want my 2018 to do the same, but the higher battery temperatures might not let that happen. It is a fact that a li-ion battery loses capacity faster if it's hot while charging, and it's really bad if it's hot and 100% charge. I have been monitoring internal temperatures with iStat Menus, and I notice my thin, powerful new 2018 13" MBP runs hotter than my old 2011 15" MBP, and I am concerned about the battery temperature. My answer is going to make you even more paranoid though. I edit photos and video which often get the fans going, yet I have never seen heat-related screen damage, so I never worry about it. I have used Mac laptops for over 20 years, often in clamshell mode (closed) with a monitor attached.
