Fan Control vs G-Helper

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.

G-Helper is a free, portable Windows control tool for Asus laptops and handhelds. It brings together performance, fan, GPU, battery, and RGB controls in a single executable that does not require installation. Performance modes are Silent, Balanced, and Turbo, with built-in fan curves; GPU modes are Eco, Standard, Ultimate, and Optimized. Dedicated GPU controls include core and memory clock offsets, GPU power, Dynamic Boost, and temperature limits. Automation can change performance mode, GPU mode, screen refresh rate, and keyboard-backlight timeout according to AC or battery power. An in-game overlay reports FPS, CPU and GPU temperatures, fan RPM, and power draw. Selected Asus mice, keyboards, and headsets can have lighting, bindings, equalizers, and battery settings. The app checks Asus for model-specific BIOS and driver updates and uses the Asus System Control Interface driver plus BIOS-stored operating modes. It requires the .NET 10 Desktop Runtime and that Asus driver. The desktop application says it does not collect or transmit personal data.
