I have the same issue, new ryzen 2700x build, properly applied thermal paste (more than enough), high end cpu air cooler (Dark Rock Pro 4) and I get 90-120 C while in Msi Bios it says 32-38 C. I also had the same problem with my older cpu (A8 6600k) and also the vram of my Gtx 1060 6gb is shown as 2048mbs. I hope they fix this problems.
