NVIDIA显卡在硬件上有温度传感器，可以感知显卡的运行环境。温度数据的获取，一般是通过调用NVIDIA的SDK的相关函数即可。SDK的下载的网址（https://developer.nvidia.com/nvapi），里面有一些sample code可以参考。获取温度的函数是NvAPI_GPU_GetThermalSettings。参考代码如下:
int main() { NvAPI_Status ret = NVAPI_OK; ret = NvAPI_Initialize(); if(ret != NVAPI_OK) { printf("NvAPI_Initialize() failed = 0x%x", ret); return 1; // Initialization failed } NvPhysicalGpuHandle hPhysicalGpu[NVAPI_MAX_PHYSICAL_GPUS]; for (NvU32 PhysicalGpuIndex = 0; PhysicalGpuIndex < NVAPI_MAX_PHYSICAL_GPUS; PhysicalGpuIndex++) { hP
