ThermalForge

ThermalForge is a free, open-source fan control application specifically designed for Apple Silicon Macs, offering both a menu bar app and a command-line interface. Key features include a smart adaptive fan curve, real-time temperature monitoring from multiple sensors, proactive cooling, thermal data logging, and a safety override mechanism that enforces fan speeds during critical temperature events. Unlike commercial alternatives, ThermalForge requires no subscriptions or telemetry, making it a robust solution for advanced fan management on compatible macOS systems.
