Re: 970 Extreme4 wrong temp and no fan speed

Just some ideas for you. Since you use Ubuntu, you obviously cannot load any of the standard Windows drivers provided by ASR for your AMD board. On new Intel chipset boards, there is software called the Management Engine, that is needed in order for the platform to function correctly. Does AMD have a similar type of software that you could not load in the Ubuntu environment, that may be causing this problem?

Have you used Ubuntu and the programs you listed on other motherboards, and they worked correctly? Can you determine which sensor chip your board is using, and if the programs you use are compatible with it? Are you sure those programs are compatible with the new AMD CPUs, such as your FX 8120?

In the Windows environment, when running multiple hardware monitoring programs at the same time, it is not unusual for one of the programs to get bad data. I don't know if you are doing that, just FYI.
