Fan Control vs Handheld Companion

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.

Handheld Companion is a free, open-source Windows app for handheld gaming PCs, with touch-optimized controls and device settings. It maps controller inputs to keyboard, mouse, joystick, trigger, or virtual controller actions, including Xbox 360 and DualShock 4 output. Universal Motion Control translates supported motion sensor data for aiming, camera control, racing, and emulators. QuickTools adjusts TDP, frame limits, refresh rate, resolution, brightness, volume, and power mode. The app can detect the active game and apply saved controller, motion, graphics, and power preferences automatically. Listed device families include ROG Ally, Steam Deck, Legion Go, MSI Claw, AYANEO, and GPD Win. Steam Deck support applies to Windows 10 or 11 installations; this is not a SteamOS application. The free public release costs nothing for Windows 10/11 on x86 and x64. Installation requires administrator rights to deploy services and drivers.
