Hi,

Translating this, fan2 (the one with the high reading) would be one of
the CPU fans. The CPU fans are pin multiplexed, meaning you'll never know
which one of the fan speeds is really reported, as the pin multiplexing
is not supported by Linux. I have no idea why it reads such a high speed.
Is this a standard fan ?
Fans 3..5 are read via direct MMIO, ie not through the NCT6775, and also not
supported in Linux. If you want to see the speed of a chassis fan, you would
have to connect it to the header for chassis fan 1.
The alarms are because the min/max values are not configured. You would
have to specify limits in the configuration file and apply as appropriate.
There is a scaling factor for most of the voltages, but unfortunately the ASRock
utility doesn't specify it, or I don't know how to interpret it. So you'll have
to figure it out based on the raw voltages.
See http://www.lm-sensors.org/wiki/Configurations/ASRock/AM2NF3-VSTA for an
example configuration file for another ASRock board, and
http://www.lm-sensors.org/wiki/VoltageLabelsAndScaling for how to find the
specific values for your board.
