It uses the "old" registers for the min speed settings, so presumably that should be correct. Yet, there must be a reason for the alarm. Maybe it is the "maximum RPM" register after all - the NCT6775F has that set of registers as well. Robert, can you play with the min speed setting a bit and see if you can get the alarm to disappear ?
