I've tested your revised patch and it works on my V2 board too. I've
removed the stuff (alarm limits, for which the interrupts are disabled
anyway) that have nothing to do with fan regulation and it works still
(with and without the it87 module). It turns out that the zero degree
voltage setting 0xec is actually a lot better than the 0xe5 my shipped
bios put in. The 0x87 for the index 0x14 was just my mistake, 0xb7 is
the correct value.
I've changed the index 0x13 value to 0x75 to make both FAN1 and 3
'smart'-regulated. I hope that is correct for your boards too, if it
works fine, we don't need a different setting for V1 and V2 boards after
Please find the revised-revised patch attached.
