Macs Fan Control

Macs Fan Control is a free app from CrystalIdea Software Inc. for better control over Mac cooling fans, letting you set individual fans to a constant speed or control them in relation to a specific temperature sensor, from built-in Apple sensors to third-party hard drive and SSD SMART data. You can set minimum and maximum thresholds, display thermal sensor data, display a temperature and fan speed in the Mac menubar, and even use it with Windows running in Boot Camp.

Macs Fan Control 1.5.4 is a free download for macOS 10.12 and up with earlier versions available for Mac OS X 10.6 to OS X 10.11. A $14.95 “Pro” version brings custom fan presets, plus “priority customer support and confidence in future updates and improvements.” The latest release now works in Windows 10 also on modern computers that have the T2 security chip.
