In their own words
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.
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.
