with driver 19.12.2 vrm temp is showing but gpu thermal diode and memory etc, shows the same value, so i think this is not a problem since its showing vrm and gpu temp.
i havent tried with the older driver since this is my first upgrade from ryzen 2200g to 3600 and rx580.
Thank you for the data.
Those temperature values come from the driver and Polaris GPUs are not expected to return additional temperature values (like Memory, PLX and Liquid). So this is most likely a driver bug.
If HWiNFO was showing a discrete GPU VRM sensor and now it doesn't you might try to reset the GPU I2C Cache in HWiNFO. If that won't help, it's also likely that the new driver blocks access to the VRM.
