If I'm not mistaken, the values should come from the setup created in /etc/sensors.conf. I guess if things aren't setup properly there, then the values you get don't much make sense. I for one can't imagine my system doing anything useful if the 3.3V really would be 1.54V. I'm sure something's not set up correctly there.
You are right, you have to adjust the multipliers in /etc/sensors.conf For example, for my motherboard which uses via686 chip I had to make the following changes in the section chip "via686a-*": compute "2.0V" 1.02*@ , @/1.02 compute "3.3V" 1.02*@ , @/1.02 compute "5.0V" 1.02*@ , @/1.02 compute "12V" 1.02*@ , @/1.02 set fan1_div 8 ignore fan2 To calculate the coefficients compare the values reported by sensors to the ones reported by BIOS. You can also rename some sensores and/or exclude them from report. So here is my complete chip "via686a-*" section for the Gigabyte GA-6VTXE-A motherboard: chip "via686a-*" label "2.0V" "CPU core" label "2.5V" "+2.5V" ignore "2.5V" label "3.3V" "I/O" label "5.0V" "+5V" label "12V" "+12V" label fan1 "CPU Fan" label fan2 "P/S Fan" label temp2 "SYS Temp" label temp1 "CPU Temp" label temp3 "SBr Temp" ignore temp3 set in0_min 1.4 set in0_max 1.6 set in2_min 3.3 * 0.95 set in2_max 3.3 * 1.05 set in3_min 5.0 * 0.95 set in3_max 5.0 * 1.05 set in4_min 12 * 0.95 set in4_max 12 * 1.05 set temp1_hyst 45 set temp1_over 50 set temp2_hyst 45 set temp2_over 50 set temp3_hyst 60 set temp3_over 65 compute "2.0V" 1.02*@ , @/1.02 compute "3.3V" 1.02*@ , @/1.02 compute "5.0V" 1.02*@ , @/1.02 compute "12V" 1.02*@ , @/1.02 set fan1_div 8 ignore fan2 To make sensors recognize new settings run "sensors -s" as root. After that sensors report for me: via686a-isa-0c00 Adapter: ISA adapter CPU core: +1.58 V (min = +1.40 V, max = +1.60 V) I/O: +3.38 V (min = +3.13 V, max = +3.47 V) +5V: +5.08 V (min = +4.75 V, max = +5.26 V) +12V: +12.18 V (min = +11.39 V, max = +12.61 V) CPU Fan: 1654 RPM (min = 0 RPM, div = 8) CPU Temp: +38.5°C (high = +50°C, hyst = +45°C) SYS Temp: +33.5°C (high = +50°C, hyst = +45°C) -Kastus
