There's no reason to be worried about such temperatures for the VRs, since they usually run at higher temperatures. On some boards under load, the VR temperature can easily hit 80-90 C. All depends on VR cooling provided by the manufacturer - some ship boards with passive and some active VR cooling. If you'd like to bring the values down, you might adjust your case fans to blow air at the VR part.
I have also a question

I see you have the new series Gigabyte mainboard, which yet lacks proper sensor adjustments in HWiNFO. Could you please help me with this? If you would attach/send me the HWiNFO Debug File with sensor data and a screenshot of Gigabyte Easytune tool showing actual temperature/voltage/fan values, I could adjust HWiNFO to show proper values too.
