After staring at the numbers for a while I've noticed that they do vary slightly, so it's likely that something is actually connected. The raw values (/proc/sys/dev/sensors/w83697hf-isa-0290/in5) I've seen for in5 so far are 3.01 and 2.99 (187/188 on the ADC), in6 does 3.02 through 3.06 (189/191). I've also looked at the datasheet for the w83697hf now, but that didn't yield anything beyond that something strange is going on. My R3/R4 ratio appears to be about 25.4, and my R5/R6 ratio is about 14.4, that is if my power supply is perfect. I guess I'll have to reboot to see what the BIOS says. These values work out to the following lines in the configuration file. compute in5 (26.44 * @) - 91.58 , (@ + 91.58) / 26.44 compute in6 (15.36 * @) - 51.69 , (@ + 51.69) / 15.36 Note the huge multipliers, the values are jumping up and down in increments of about 0.3V for the -5V and 0.5V for the -12V now. That's way too much, so I'm guessing ASRock changed the offset voltage as well. I've emailed them, we'll see what happens. Incidentally, the values for +5 and +12 seem to be off as well, at 4.84V and 11.25V. I'm ready to chalk that up to the use of cheap large-tolerance resistors though. I did the numbers based on the datasheet and assuming my +12v really is +12v, R1/R2 works out to be about 3.0, which is about 8% higher than the 28K/10K given in the datasheet. That's within the margins for 5% resistors. > You can add ignore statements to /etc/sensors.conf. > > First find your chip configuration part and use the > ignore statement. > > like ignore inX where X would corresspond to the label inX > statement. ignore in6 > ignore in5 But that wouldn't solve anything...

Setting the divisor to 4 did the trick here. Thanks! Lourens -- GPG public key: http://home.student.utwente.nl/l.e.veen/lourens.key
