OK Here's the infomation
nct6776-isa-0290
Adapter: ISA adapter
Vcore:       +1.18 V  (min =  +0.00 V, max =  +1.74 V)
in1:         +1.02 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
AVCC:        +3.36 V  (min =  +2.98 V, max =  +3.63 V)
+3.3V:       +3.34 V  (min =  +2.98 V, max =  +3.63 V)
in4:         +1.03 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
in5:         +2.04 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
in6:         +0.78 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
3VSB:        +3.42 V  (min =  +2.98 V, max =  +3.63 V)
Vbat:        +3.30 V  (min =  +2.70 V, max =  +3.30 V)   ALARM
fan1:        550 RPM  (min =    0 RPM)  ALARM
fan2:       1013 RPM  (min =    0 RPM)  ALARM
fan3:          0 RPM  (min =    0 RPM)  ALARM
fan4:        824 RPM  (min =    0 RPM)  ALARM
fan5:          0 RPM  (min =    0 RPM)  ALARM
temp1:       +24.0째C  (high =  +0.0째C, hyst =  +0.0째C)  ALARM  sensor = 
thermistor
temp2:       -60.0째C  (high = +80.0째C, hyst = +75.0째C)  sensor = diode
temp3:       +38.0째C  (high = +80.0째C, hyst = +75.0째C)  sensor = 
thermistor
cpu0_vid:   +2.050 V

and BIOS
CPU temp 43
MB temp 25

CPU Volt 1.114-1.1176
3.3Volt     3.36 - 3.34
5Volt     5.160
12Volt  12.288

So it looks as if in4 * 5 is 5Volt, in5 * 6 is 12volt. This is on a asus 
p8p67 pro, but I've seen the same values on a asus p8p67 delux.

Looking in the n6776f specification if looks as if AUXTIN(temp3) and in6 
share the same pin (pin 109) so we can't have both enabled.

Ian Dobson
