lol I also have this issue and I'm not even running intel, built a brand new ryzen 5 rig late last year and my asus b-150 prime board reads the same thing in speccy. All my old pcs I've built have read rediculously high for Mb temp in speccy aswell. I came to the conclusion a while ago that I will forever ignore this bug and will definitely find an app that yea know...
Works
