This just seemed really hard based on the match I'd seen done in other configurations. It didn't look like a simple "solve for X" solution. However, I guess I can just do that and see how it comes out. > * Look at the voltage values displayed by a Windows tool, and use > factors such that "sensors" will display the same values. I'm not running Windows on this machine.

But if I understand it correctly, it's not just that they use the same chipset and sensor chips, but the resistors they use could easily be different (even the type of heat sensor, for example), right? > > This is tricky either way.

Is it true that I'm the first person to try to get the sensors package running on this particular mother board? When I chose this board, I had lm-sensors in mind, but I guess I didn't do a good enough job.

Ah... this could explain a lot. I hadn't considered getting a newer version, and feel silly for that now.

If it really is using the IT8716F, then I think I read something somewhere that this chip is not really supported yet, and a kernel patch was required.

Thanks so much for your help, Jean. I knew I must have been doing something wrong. I'll be back once I get the new version up and running and work through getting a configuration file up and running.
