Macs Fan Control
Macs Fan Control is a free temperature monitoring and fan management utility for macOS developed by CrystalIDEA. It displays real-time readings from all thermal sensors in your Mac (CPU, GPU, SSD, memory controller, battery) and lets you override Apple's default fan curves with custom RPM values or sensor-based profiles. The app is particularly popular among power users running demanding workloads like video editing or 3D rendering, iMac owners who have replaced the original hard drive with an SSD, and anyone who wants to reduce fan noise. It is not available on the Mac App Store due to the low-level hardware access it requires, but is freely downloadable and includes a Pro tier with presets and advanced automation.

1 suggestionMacs Fan Control ships as a Universal Binary that runs natively on both Intel and Apple Silicon Macs, and the current version (1.5.21, released in 2026) includes full support for the latest Apple Silicon chips including M5. There is nothing you need to do — your copy is already running natively if you have updated to a recent release. If you are running an older version, visit macsfancontrol.net to download the latest build; it will install the native version automatically on Apple Silicon Macs. All existing settings and presets will be preserved. You will see no material performance difference compared to older builds since the app's primary job is hardware monitoring rather than CPU-intensive computation, but staying current ensures compatibility with the latest macOS releases and newest Apple Silicon models.
