# NVFC: recovering undocumented NvAPI GPU controls > NVFC implements undocumented NvAPI interfaces for NVIDIA GPU monitoring and configuration. The author recovered the interfaces by observing nvapi_QueryInterface calls in existing utilities; the C++ tool reads clocks, voltage, temperature and fan state and can set fan behavior. - Type: Case study - Targets: App - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-11-08 - Added to the catalog: 2026-11-09 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/nvfc-case/index.md) ## Requirements & limits - **Prerequisites:** Windows 7, 8 or 10; NVIDIA display driver 384.76 or later and a 400 Series or newer GPU. - **Prerequisites:** Visual Studio 2017 for the supplied C++17 solution. - **License:** No licence file in the repository. ## Primary sources 1. ## More in Apps - [SingStar Mic: reconstructing the microphone app protocol](https://awesomerea.org/resources/singstar-mic-protocol-case/index.md) · Case study - [Techstream for Linux: recovering Toyota diagnostic formats and workflows](https://awesomerea.org/resources/techstream-linux-case/index.md) · Case study - [Fluval Plant Pro 4.0: reconstructing BLE light control](https://awesomerea.org/resources/fluval-plant-pro-4-ble-case/index.md) · Case study - [xtractedott: reconstructing the OTT compressor DSP core](https://awesomerea.org/resources/xtractedott-case/index.md) · Case study - [OpenApe: reconstructing the Call of Duty 4 Asset Manager](https://awesomerea.org/resources/openape-case/index.md) · Case study - [EOO: a Nintendo DS Wii-connection utility decompilation](https://awesomerea.org/resources/eoo-wii-connection-utility-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
