Summary
ASUS GPU Tweak III is free Windows software for adjusting system settings on NVIDIA and AMD desktop graphics cards. Its tools cover overclocking, voltage and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves the result as a profile without overwriting driver data. The Voltage-Frequency Tuner provides several ways to manage the GPU boost curve, while Profile Connect can load linked overclock, fan-curve, and on-screen display settings when a selected application runs. Users can set curves or fixed RPM values for GPU fans and system fans connected to FanConnect headers. Monitoring features track fan speed and system power, display information over full-screen applications, and export logs for analysis. The OSD allows changes to metric font, color, opacity, size, and position. A hardware plug-in adds live statistics for components such as the motherboard, processor, and storage devices. ASUS lists Windows 10 and 11, at least 2 GB of RAM, and 200 MB of storage as minimum requirements for most versions.
