Any computer – whether it be a super-powered Mac Pro or the thinnest MacBook with passive cooling – generates heat during work and you won’t get away from it. It is quite normal as long as the temperature stays within acceptable limits. However, if the cooler is running at full throttle and the laptop burns your hands, it’s high time you did something. We have been researching the issue and managed to find a couple of fixes that are worth trying.
The program allows Mac users to track fan speed and temperature easily. First of all, with these measurements, you will be able to monitor if your further steps are helpful. Secondly, it has an option to regulate the fan speed and, thus, reduce overheating.
Change Graphics and Battery Life Settings
You may try the following simple Settings change to lower the temperature of the device:
- Find System Preferences, go to Energy Saver and uncheck the box Automatic Graphics Switching. Doing so, you will make sure that your device’s components won’t switch between multiple elements in order to get higher graphics performance and will use only the ones they are optimized for.
- Find System Preferences, go to Energy Saver, proceed to Graphics and select Better Battery Life. It will increase the battery life, slightly reduce the performance of the device and lower overheating.
Disable Adobe Flash
Apparently, flash games, videos and so on require a lot of power from your Mac’s processor. Moreover, sometimes Adobe Flash and Mac may be incompatible. We recommend disabling flash and enabling html5 instead. In order to disable Adobe Flash in Safari, open the browser, go to Preferences, then Security and in Web content, uncheck the Enable plug-ins option. For Firefox, check Disable flash in the Preferences section. Also, if you wish to decide whether to disable flash on a particular website, simply download FlashBlock on your computer.
Check the Activity Monitor
Activity Monitor provides shows which processes are running on your Mac and how much memory they are using. This allows you to find out which program is causing overheating. For that, go to Utilities and drag it right onto the Dock so that you should have a live status of the CPU usage. If you see that a certain application consumes lots of CPU time, just close it in the standard way. However, we recommend you not to force quite the unknown processes or the ones such as WindowServer, kernel_task or mdworker, as those may be the system tasks running in the background.
Set the device on a flat surface
This obvious, though, really important advice is still neglected by many Mac users. Working in bed or with lots of soft cushions on the couch will surely cause the increased heating depending on the intensity of the work. The reason is simple: the ventilation openings are blocked, and the natural air circulation is broken. Therefore, if you cannot work at the table, try to install the computer on flat surfaces. In bed, for example, you can use a special stand or just a large book placed on the pillow.
By following the tips above, you will certainly reduce the temperature of your Mac and won’t need to worry about overheating. If the described recommendations do not help and the Mac continues to warm like a stove, don’t leave it too long and contact the service center.
