HWiNFO and GPU-Z have implement the "gpu memory junction temperature" for rtx3080/3090 gddr6x vram.

I'm trying to find such function to get vram temp in nvapi but got no luck.

The closest stuff I found was NvAPI_GPU_GetThermalSettings(nvGPUHandle[id], NVAPI_THERMAL_TARGET_MEMORY, &thermalSettings);but the resultthermalSettings.sensor[0].currentTemp was 0x FFFF FFFF CCCC CCCC`, which means the vram temp feature is not implemented.

Through LOTS of googling I found your repo which have some undocumented nvapi query functions.

Is there any nvapi function that can get the vram temp? I'm begging for your help.
