Core-Monitor

Core-Monitor reads sensor data from the SMC and system APIs and shows it in the menu bar, a dashboard, and on the Touch Bar where present. It covers CPU, GPU, memory, battery, thermals, power draw, fans, network and disk.

Fan control goes through a privileged helper that hands control back to macOS when you stop or the app disconnects. The project supports only Apple silicon and macOS 13 or later. It is available as a direct download and on the Mac App Store.
