ASUS GPU Tweak III vs G-Helper

ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.

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.
