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.

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: +46.0?C (limit = +65?C, hysteresis = +55?C) sensor = 3904 transistor temp2: +42.0?C (limit = +65?C, hysteresis = +55?C) sensor = 3904 transistor temp3: +45.0?C (limit = +65?C, hysteresis = +55?C) sensor = 3904 transistor tyrex:~# sensors | egrep ^temp temp1: +46.0?C (limit = +65?C, hysteresis = +55?C) sensor = 3904 transistor temp2: +43.0?C (limit = +65?C, hysteresis = +55?C) sensor = 3904 transistor temp3: +46.0?C (limit = +65?C, hysteresis = +55?C) 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.
