Sorry about that.
They don't. hwmonitor in Windows gives you the correct mapping for your
board.
Voltage 0 1.11 Volts [0x8B] (CPU VCORE)
Voltage 1 0.69 Volts [0x56] (VIN1)
Voltage 2 3.30 Volts [0xCE] (+3.3V)
Voltage 3 4.97 Volts [0xCF] (+5V)
Voltage 4 11.54 Volts [0xCF] (+12V)
Voltage 5 1.69 Volts [0xD3] (VIN5)
Voltage 6 1.90 Volts [0xED] (VIN6)
where Voltage X maps to inX.

I though about it too at first, that Voltage X corresponds to inX in lm-sensors. The problem is, if you look at the default configuration lm-sensors provide at /etc/sensors3.conf:
chip "w83627ehf-*" "w83627dhg-*" "w83667hg-*" "nct6775-*" "nct6776-*"
label in0 "Vcore"
label in2 "AVCC"
label in3 "+3.3V"
label in7 "3VSB"
label in8 "Vbat"
set in2_min 3.3 * 0.90
set in2_max 3.3 * 1.10
set in3_min 3.3 * 0.90
set in3_max 3.3 * 1.10
set in7_min 3.3 * 0.90
set in7_max 3.3 * 1.10
set in8_min 3.0 * 0.90
set in8_max 3.0 * 1.10
You can see that in3 is "+3.3V". Of course I tried modifying in3 in my configuration as follows:
That is just a generic description for settings which are
often seen for those SuperIO chips. That doesn't mean they
apply in any way to your board.
label in3 "+5V"
set in3_min 5 * 0.95
set in3_max 5 * 1.05
compute in4 @*((20/10)+1), @/((20/10)+1)
You'll need the correct compute statement for in3.
You are labeling in3 as 5V and then provide a compute
statement for in4.
Where is the compute statement for in3 ?
And here's the result:
# sensors -s
# sensors

CPU Temp: +38.5°C (high = +60.0°C, hyst = +55.0°C) sensor = thermistor
As you can see:
+5V: +9.89 V (min = +2.98 V, max = +3.65 V) ALARM
doesn't look right, and even the min and max values does not reflect the ones I set. Moreover, it looks as though in3 is really "+3.3V" in lm-sensors.
But if I modify in4 in my configuration as follows:
##### in4 as +5V monitor
label in4 "+5V"
set in4_min 5 * 0.95
set in4_max 5 * 1.05
compute in4 @*((20/10)+1), @/((20/10)+1)

As you can see from above, I was able to successfully modify in4, and set min and max values for both +5V and +12V and showing the values as expected.
So what is the reason for this behavior?
PDL, or Pure Damned Luck. You are using the fact that both in3 and in4
happen to report the same physical value to your favor. That doesn't
make it correct.
