In their own words
Fan Control
Fan Control is free Windows software for configuring CPU, GPU, and case fans across supported motherboards, graphics cards, AIOs, and other hardware. It offers seven documented curve types: RPM mode, Linear, Graph, Mix, Trigger, Flat, Sync, and Auto. Users can calibrate controls and adjust response time, hysteresis, RPM avoid zones, step-up and step-down behavior, and fan start or stop logic. Multiple profiles can be saved, edited, and loaded, with guided setup on first launch. Custom sensors can average or combine readings, apply offsets, or read temperatures from files. Mix curves can combine inputs using maximum, minimum, average, sum, or subtraction. Community.NET plugins add temperature, speed, or control sensors, with integrations listed for HWInfo, Home Assistant, Thermaltake, Corsair, Aquacomputer, NZXT Kraken, Lian Li, and others. The backend mainly uses LibreHardwareMonitor. Windows 10 and 11 are supported, with portable, installer, Scoop, Winget, and Chocolatey options. The plan is free.
