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. When using the sensor adapter, no additional software is required.Most of the time, you don’t need to worry about your Mac’s temperature. This type of cable converts a plug-in sensor to an adhesive one, which allows the fan speed to be automatically controlled by the iMac system management controller.

This allows the user full control of the fan speed to set it to an acceptable level. One solution is to use a third-party software such as SMCFanControl. You will probably want to reduce the speed of the fan, as well as the noise. One of the benefits of SSDs is that they generate significantly less heat in comparison to a traditional HDD, so the increased fan speed is unnecessary. Please note that any iMac that uses a ‘sticky pad’ sensor can simply be re-attached to the new SSD and fan speed is unaffected. When you power on your iMac, the temperature will incorrectly register as much higher than normal and the fan speed will increase as a result. Solid state drives (SSDs) and the accompanying 2.5” to 3.5” converter bracket do not use this type of socket, meaning that the cable cannot be reattached. Some earlier iMacs systems use a separate plug-in temperature sensor cable, which attaches to a socket on the original hard disk drive (HDD) to determine the drive temperature and adjust the fan speed accordingly.
