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...
