In their own words
Gainward ExperTool
Gainward ExperTool is a free Windows utility for tuning graphics-card performance and desktop management. Gainward positions its dedicated Expert Tool for overclocking. ExperTool II adds flexible fan curve control and a BIOS saving feature, and also offers LED lighting control for ARGB effects. Gainward says fans stop during multimedia or general workloads and start under heavier loads when GPU temperature exceeds 60°C. Download requirements depend on system architecture and Nvidia driver version: the 64-bit download is listed for Nvidia GPUs with driver 436.xx or newer, while 32-bit downloads specify drivers 415.xx or newer and 347.xx or newer. The listed 64-bit package is version 11.13, dated 2025-02-19, and is 16.5 MB. Its supported Windows versions are Windows 7 (64-bit), Windows 10 (64-bit), and Windows 11. Gainward was founded in 1984 and is headquartered in Taipei, Taiwan. Warranty and return handling goes through authorized distributors or the original store.
Green Curve
Green Curve is a free, open-source utility for adjusting NVIDIA GeForce GPU behavior on Windows and Linux. It can inspect and edit live voltage/frequency curves, core and VRAM offsets, power targets, and fan settings. Supported GeForce architectures run from Pascal through Blackwell, with a best-effort fallback for future architectures. Users can save five profiles, switch them with global hotkeys, or switch automatically based on the foreground application. Fan options include driver auto, fixed speed, and temperature curves with up to eight points. A command-line interface supports hardware probing, profile changes and live-state output in text or JSON. Windows has a native GUI; Linux has a keyboard- and mouse-navigable terminal UI. The application loads NVAPI and NVML from the installed NVIDIA driver rather than bundling proprietary driver binaries. The project states it has no telemetry, analytics, cloud tracking or remote error reporting. Windows x64 and Linux x64 are validated on NVIDIA hardware; ARM64 platforms are compile targets without completed live hardware validation. The project warns that tuning may cause instability or hardware damage.
