How to View CPU Temp and Fan Speeds on Mac

System monitoring apps and widgets are nothing new on Mac. Peer inside the App Store and you’ll find handfuls of them, and look beyond the App Store to find dozens more. The problem is, most of them are outdated or pricey.

And most of them don’t include CPU temperature or fan speed data, both of which are important for diagnosing excessive heat in your computer.

I don’t like to spend money when I don’t have to, so color me surprised (and satisfied) when I found Fanny, a free Notification Center widget that’s both minimalist yet informative. As far as I’m concerned, this is a must-have Mac app.


Long story short, you install the app (using any of the normal installation methods) and then add the widget to your Notification Center. It also appears in the menu bar, which you can click for more info. It shows your current CPU temperature and the speeds of every fan in your system.

And best of all, it’s 100% free.

It’s really as simple as that. The next time your fans go on blast, check your CPU temperature. If it crosses the 60C threshold, you may want to look more into it. High CPU temperatures are not good over the long term.
