I got the datasheets, (-P version is novuton, the other one is
winbond), and there are pretty similar.

The hardware monitoring chapter is pretty similar. Section 5 (PECI) is
completely rewritten. Section 6.3 has some differences, it looks -P
has new smart fan III+ feature. Section 6.3.4 (smart fan III+) is
new. There are differences in 7.1.3.1. section, but that is some SMI
interrupt stuff, not interesting for us.

Chapter 8/9 (hardware monitor register set) has completely different
graphics... but seems to describe same hardware. Hmm, it has even the
same value (5CA3) in the identification register. Sections .70-.84 seems to
describe new registers for smart fan III+ mode and more. And there are
more new registers near section .98 and .119.

But it seems hardware should be backwards-compatible...
