Looks great (except the alignment which is discussable, but that's not
really important).

Yes, it is.

Obviously, we could live without the extra precision, but that's a funny
feature.

No, you're right. I'll need some time to implement what Alex suggested.
It's something relatively new for us, and I don't know how we can handle
this both cleanly and user-friendly.

I don't really understand what you mean, so yes, you must have had
something strangely configured before.

> What is the meaning/purpose of tcrit over temp_high?

They generate different signals when reached. The exact actions depend
on how your hardware is wired. For example, being over temp_high may
trigger an extra fan or CPU throttling, while being over tcrit would
shut down the system. Read the LM90 data sheet if your interested in the
details:
