Although most of Apple's  Macs come with highly efficient cooling designs, there are times when intensive processing tasks such as video rendering and audio design put an enormous strain on the CPU.

If you need to stay on top of the situation and to keep a close eye on your Mac processor's temperature, it is a good idea to have an app capable of monitoring it one look away at all times.

Temp  Monitor is a macOS application specifically designed to watch a Mac processor's temperature very closely and  display it in the menu bar in the form of a text- and icon-based status item.

More precisely, Temp  Monitor runs in the background and will let you know when the CPU's temperature reaches dangerous levels, thus enabling you to pause highly intensive processing tasks and resume them at a later time to protect your Mac's integrity.

The CPU temperature which triggers Temp Monitor to  display an overheat notification can be customized via the app's settings window. From there you can also set Temp Monitor to launch on login and choose the default temperature unit it uses.

The Temp  Monitor utility displays audio and visual notifications via macOS' Notification Center feature, and it they are by default set to be alerts which will not go away until manually dismissed, an excellent idea for when you are away from your Mac and the CPU temperature goes above the safe threshold.

The temperature warnings are also added automatically to Notification Center's notifications tab, for later reviewing of all past alerts when and if needed.

As a downside, when clicking the "Configure Notifications" in Temp  Monitor's Settings window, you are directed to System Preferences' main screen instead of the Notifications preference pane.

To summarize it all, the Temp  Monitor app is an unobtrusive tool which will alert you when your Mac overheats, and the perfect utility to help you log all instances when the processor goes beyond a temperature which might be dangerous for both your Mac and yourself, if you're using a  MacBook or  MacBook Pro.
