When adjusting your fan settings, it’s best to err on the side of caution and perhaps consider making small changes, slowly, just to make sure there’s no negative side effects. Running your fans at maximum speed for a significant period of time can damage your Mac, and if you push the CPU too hard then it’s possible your Mac may start to overheat, even with the fans at full blast.Īt the other end of the scale, if you tell macOS to wait too long before activating the fans, then your Mac may be nice and quiet but it may also be internally burning up! Regardless of whether you’re cranking your fans up or down, it’s important to monitor the temperature of your CPU and other components, to make sure your manual tweaks aren’t damaging your system. In this article, I’ll show you how to manually configure your fan settings, using the free Macs Fan Control application.

As ever, there’s a downside: your system will get hotter, quicker, so macOS is more likely to throttle your CPU and make your Mac run noticeably slower, even when you’re not doing anything particularly strenuous. This performance boost comes at a cost, as your fans will be noticeably louder, which may be difficult for some users to deal with, or could even be embarrassing if you’re using your Mac around other people, such as in an office or cafe.Īlternatively, if you find the sound of the fans grating, then you can turn them down a notch. By configuring your fans to kick in at lower temperatures you can push your Mac harder, without macOS stepping in and throttling your CPU. Whenever your Mac’s temperature starts to rise, macOS automatically throttles your CPU to give the temperature a chance to return to normal. However, there are some benefits to manually adjusting your fan settings.

Your laptop’s built-in fans will go faster when your Mac starts to get hot, and slow down once the temperature returns to normal, all with zero interference from you. Most of the time, you don’t need to worry about your Mac’s temperature.
