That will sort the CPU usage based on the highest first.

Here is how you can go about it: Image Source: Ask Different Stack Exchange When you catch those, end those processes to give your Mac some rest. To end this, you need to head to the Activity Monitor app and then look for the processes making Mac’s processor work harder than it normally should be. The more intensive tasks it has to perform, the more heat it will produce. Take note you are limited to the minimum value that Apple sets, so you can’t damage your hardware.A high load on the machine’s processor also causes it to overheat. If you’re having a noise problem, you can lower this value, but make sure you keep an eye on the temperatures. This fan control tool has been used for years to set a minimum rpm value for the built-in fans. Also, it’s free, so it’s worth trying it out before buying a premium app. Keep in mind that it won’t work on the new M1 Macs, but it should be compatible with the Intel builds. Displays a status bar with current fan speed and HDD temperature.Īlthough smcFanControl is outdated because it has been discontinued, you can still use it on an older iMac, MacBook Air, or MacBook Pro.Controls the fan automatically for optimal HDD/SSD cooling.If your HDD or SSD doesn’t come with a SMART interface, the app will still approximate the temperature of your hardware based on the other sensors.įind the right balance between temperature, cooling, and noise by setting a custom relationship between fan rpm and HDD temperature. Instead, it uses the hard disk’s integrated SMART interface to get the data it needs. The best thing about HDD Fan Control is that it doesn’t rely on Apple’s temperature sensors.
