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.
PenguinBurner
PenguinBurner is a free, open-source Linux application for tuning NVIDIA GPUs through automatic undervolting, overclocking, and per-game profiles. Auto-UV runs a managed Q2RTX benchmark and CUDA load, then finds and verifies stable voltage-frequency settings. Adaptive mode switches among saved Efficiency, Balanced, and Performance tiers to pursue a game's FPS target and reduce power use when headroom exists. Profiles work with Steam, Lutris, and Heroic, applying at launch and restoring the standing profile when a game exits. An overlay can display base FPS, frame-generation FPS, latency, clocks, power, temperatures, and the active tier. Manual voltage-frequency and fan-curve editors are included, along with a generated silent fan curve. The install guide lists NVIDIA RTX 30, 40, and 50 cards and requires the proprietary NVIDIA driver and CUDA. Linux installation options include pip, Flatpak, Fedora COPR, AUR, and Ubuntu PPA packages.
