Unfortunately, I was unable to note any differences in the voltages after setting all pwm values back to 0. I also played around with it some more, but nothing changed in the output of sensors. Strangely, all of a sudden, echoing new pwm values (0 means full speed and 255 is lowest) will change my fan speeds again and sensors will report overflows like it had been doing before. I have no clue what could have caused this sudden change, since I have not compiled/installed anything new or done anything different while booting my computer. Also, I don't recall anytime when pwm might have been forceably enabled. I played with changing min and max values in sensors.conf and all that works well. sensors output (all pwm is 0, everything at default) pc87366-isa-ecc0 Adapter: ISA adapter +5V: +3.46 V (min = +4.48 V, max = 5.47 V) ALARM Vcore: +0.77 V (min = +3.02 V, max = 3.02 V) ALARM +12V: +6.04 V (min = +10.79 V, max = 13.18 V) ALARM 5VSB: +2.47 V (min = +4.48 V, max = 5.47 V) ALARM Vsb: +3.36 V (min = +3.00 V, max = 3.60 V) Vdd: +3.32 V (min = +3.00 V, max = 3.60 V) Vbat: +0.00 V (min = +2.40 V, max = 3.02 V) AVdd: +3.32 V (min = +3.00 V, max = 3.60 V) fan1: 3503 RPM (min = 3000 RPM, div = 1) fan2: 2162 RPM (min = 2000 RPM, div = 2) S-IO Temp: +53 C (low = +5 C, high = +60 C) S-IO Crit: +70 C temp4: +36 C (low = +0 C, high = +70 C) temp4_crit: -25 C temp5: +40 C (low = +0 C, high = +70 C) temp5_crit: -25 C temp6: +36 C (low = +0 C, high = +70 C) temp6_crit: -25 C The chip dump is also attached. -------------- next part -------------- A non-text attachment was scrubbed...
