You can adjust dev.amdtemp.N.sensor_offset as needed. By default, the amdtemp sysctl gives you the unadjusted value. On different Ryzen models the raw value is wrong by different amounts. E.g. on my 1950X, I have sensor_offset set to "-27" to show correct temperature readings. See this link for a table of offset values for various Ryzen models: https://www.guru3d.com/articles-pages/amd-ryzen-7-2700-review,7.html Take care, Conrad
