Fan divisor is wrong.
adjust /proc/sys/dev/sensors/w83782d-i2c-0-2d/fan_div as needed.

thermistor type is wrong.

hard lockup on modprobe w83781d with Tyan Dual K7/Thunder

Dan, thanks, for your ultimate help on this topic.

ok, then

tyrex:~# echo "4 4 4" > /proc/sys/dev/sensors/w83782d-i2c-0-2d/fan_div
tyrex:~# sensors | egrep ^fan
fan1:     6887 RPM  (min = 1500 RPM, div = 4)                    
fan2:     7031 RPM  (min = 1500 RPM, div = 4)                    

tyrex:~# echo "1 1 1" > /proc/sys/dev/sensors/w83782d-i2c-0-2d/fan_div
tyrex:~# sensors | egrep ^fan
fan1:     7142 RPM  (min = 6000 RPM, div = 1)                    
fan2:     6716 RPM  (min = 6000 RPM, div = 1)                    

Is adjusting the min value the intended behaviour?
I also tried this in /etc/sensors.conf:
   set fan1_div 4
   set fan2_div 4
   set fan1_min 2000
   set fan2_min 2000
   ignore fan3

Again, with no success. The fan value isn't corrected. Or is this
a userland problem. (Divide yourself and get happy?)

That does the trick. I was looking at the wrong place ("w83781d")...

   set sensor1 2
   set sensor2 2
   set sensor3 2

# examples for temperature limits
    set temp1_over 65
    set temp1_hyst 55
    set temp2_over 65
    set temp2_hyst 55
    set temp3_over 65
    set temp3_hyst 55

Readings from temp2 are always lower than from 1 and 3.
BIOS says:
temp1 = cpu0
temp2 = cpu1
temp3 = chassis

I tend to distrust the BIOS and think that 1 and 3 are cpu temps,
and 2 is chassis temp, but I also tend to distrust these reading
generally, because of the low variance between the readings:
tyrex:~# sensors | egrep ^temp
temp1:    +46.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          
temp2:    +42.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          
temp3:    +45.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          

tyrex:~# sensors | egrep ^temp
temp1:    +46.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          
temp2:    +43.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          
temp3:    +46.0C   (limit = +65C, hysteresis = +55C) sensor = 3904
transistor          

More of a headache are the voltage readings:
VCore 1:   +1.74 V  (min =  +1.74 V, max =  +1.93 V)       ALARM  
VCore 2:   +2.84 V  (min =  +1.74 V, max =  +1.93 V)              
+3.3V:     +3.32 V  (min =  +3.13 V, max =  +3.45 V)              
+5V:       +4.89 V  (min =  +4.72 V, max =  +5.24 V)              
+12V:      +4.71 V  (min = +10.79 V, max = +13.19 V)              
-12V:      -2.11 V  (min = -10.90 V, max = -13.21 V)              
-5V:       +2.71 V  (min =  -4.76 V, max =  -5.26 V)              
V5SB:      +4.32 V  (min =  +4.72 V, max =  +5.24 V)              
VBat:      +3.29 V  (min =  +2.40 V, max =  +3.60 V)              
vid:      +1.85 V

VCore 2, +12V, -12V, -5V, V5SB are bogus (and no ALARM flag)

I have no idea how to correct the corresponding formulas in
/etc/sensors.conf. Does somebody did it, before?

Yes. One cpu is generally right below the power supply so the airflow is
obstructed or something, and it runs warmer than cpu0. Everyone's s2460 is
like this.

temp1:     +41.0 C  (limit =   +2 C, hysteresis =  +64 C) sensor = 3904 transistor
temp2:       +39 C  (limit =  +80 C, hysteresis =  +75 C) sensor = 3904 transistor
temp3:       +42 C  (limit =  +80 C, hysteresis =  +75 C) sensor = 3904 transistor

1. Dual Athlon XP 1800+ on Tyan Thunder K7 or Tiger MP anyone?

Erm, ???  Try www.crucial.com.  It's not quite as cheap as pc133, but it's
real close.  Where are you buying?
