I'm trying to monitor voltages on my Asus P5W DH Deluxe motherboard (using a
w83627ehg chip) with lm-sensors. The problem is the compute line for the -12V
voltage, all other readings are fine with the default settings for the w83627ehf
chip.
Using the w83627ehf/ehg datasheet as a starting point I defined the following:
# Set the -12V
label in5 "-12VCC"
compute in5 (@-2.048)*((232+10)/10)+2.048, (@-2.048)*(10/(232+10))+2.048
set in5_min -12.0*1.1
set in5_max -12.0*0.9
With this line I get:
-12VCC: -9.57 V (min = -13.25 V, max = -10.73 V) ALARM
Which leads to one or more of the followings:
1) There's a mistake in my formula
2) Asus didn't follow the datasheet guidelines for -12V external resistors (232K
e 10K) or didn't connect the -12V at all.
3) My PSU is broken
The latter is a real possibility, which is the reason I want to monitor voltages.
Any hints?
