I am running CUDA applications on a P4000 GPU. I noticed that the temperature is getting up to 82C, but the fan never goes above 63%. I dug a little further and found that the clock speeds are being reduced when this happens. I checked the throttle reason, and it is set to 0x20 (SW Thermal Slowdown).
If the device is throttling due to temperature, why doesn’t the fan speed increase to more than 63%?
