It has pins. Those pins are monitored by the driver, as specific registers. The pins wired to who the hell knows where by each board manufacturer. Sometimes the chips need special registers and capacitors Quite often, the board engineer sent to add this part to the board choose the wrong registers and capacitors, and sometimes they compensate for these errors with private tables in the BIOS or various monitoring programs which move around machine to machine. We monitor registers. We assume the vendor did the right thing. No that I've described what a shitshow it is, I hope you can adjust your expectations. Otherwise, maybe it is time to give up and delete these sensor drivers..
Boot the machine to startup BIOS. Search for a hardware monitor screen. Write down what it says - values and descriptions. Any correlation between that and what sysctl.hw.sensors says is purely in the mind of the viewer.
