NVIDIA Inspector is a free, lightweight Windows tool for GeForce GPUs. It reads clocks, temperature, voltage, and fan speed from the driver and lets you overclock, set fan curves, and manage power in real time. The package also includes NVIDIA Profile Inspector for per-game driver profiles the Control Panel does not expose. Works with GTX 600 through RTX 40 series on Windows 7–11.
