Fanny Overview
Fanny lets you keep an eye on your Mac's fans and temperatures without cluttering your workspace. It is a small menu bar app and Notification Center widget that shows the current, target, minimum and maximum speed of each fan, how many fans your Mac has, and the CPU and GPU temperature. Just open the menu bar app or Notification Center to glance at your fan stats.
Fanny is made by Daniel Storm and is free and open source under the MIT license. Version 2.3.0 needs macOS 10.13 or later. The app is built for Intel Macs; on Apple Silicon Macs it runs through Rosetta 2.
