Hi, I've found out that I made a mistake: I used the IT8712_V07 datasheet and not the datasheet for the IT8705F. That's because my last board has a IT8712F and my current board has now a IT8705F...seen it while trying to get the VID reading. However the automatic fan control registers/values are on both chipsets the same, I haven't seen a difference in the datasheets. So automatic fan control should work on both chipsets. The check for revision/version should be fixed. Regards, Sebastian
