Here is the matching data from wthe ASrock tool:

<Voltage Enable="1">
        <Item Index="0" Name="CPU_VCORE_V" Enable="1">Vcore Voltage</Item>
	<Item Index="1" Name="P3P3_V" Enable="1">+3.3V Voltage</Item>
	<Item Index="2" Name="P5P0_V" Enable="1">+5.0V Voltage</Item>
	<Item Index="3" Name="P12_V" Enable="1">+12V Voltage</Item>
	<Item Index="4" Name="CPU_NB_V" Enable="1" VoltageControl="CPU_NB_V">CPU NB Voltage</Item>
	<Item Index="5" Name="DRAM_V" Enable="1" VoltageControl="DRAM_V">DRAM Voltage</Item>
	<Item Index="6" Name="NB_V" Enable="1" VoltageControl="NB_V">NB Voltage</Item>
	<Item Index="7" Name="HT_V" Enable="1" VoltageControl="HT_V">HT Voltage</Item>
	<Item Index="8" Name="SB_V" Enable="1" VoltageControl="SB_V">SB Voltage</Item>
</Voltage>

to help you determine scaling factors.

fan1 should be connected to the chassis fan.

fan2 is multiplexed to the two CPU fans through gpio pins.
You can select one of the two with the commands provided in
https://github.com/groeck/nct6775/blob/master/README.ASRock
Use the commands provided for the ASRock 970 Extreme4.

fan3..5 are not connected to the NCT6776; don't ask me why. They are connected
to memory mapped IO. Here is the data from Asus:

<Item Name="FAN1" Bank="6" HighReg="0x56" LowReg="0x57">SYSFANIN</Item>
<Item Name="FAN2" Bank="6" HighReg="0x58" LowReg="0x59" SwitchInterface="SIO_GPIO" SwitchControl="GPIO16=Low, GPIO10=High">CPUFANIN</Item>
<Item Name="FAN3" Interface="MMIO" BaseAddress="0xFED80400" ReadingReg="0x73" WritingReg="0x23">AUXFANIN</Item>
<Item Name="FAN4" Interface="MMIO" BaseAddress="0xFED80400" ReadingReg="0x69" WritingReg="0x03">AUXFANIN0</Item>
<Item Name="FAN5" Interface="MMIO" BaseAddress="0xFED80400" ReadingReg="0x6E" WritingReg="0x13" >AUXFANIN1</Item>
<Item Name="FAN6" Bank="6" HighReg="0x58" LowReg="0x59" SwitchInterface="SIO_GPIO" SwitchControl="GPIO16=High, GPIO10=Low">CPUFANIN2</Item>

Unfortunately, there is no driver available for the memory mapped fans.

Hope that helps a bit.
