Up to kernel 2.6.13.4 the sensor readings were perfectly okay, but ever since I upgraded the kernel there were many wrong values. Right now I am running Debian/Unstable with kernel 2.6.16.4 and lm-sensors 1:2.10.0-4 on an ASUS P4C800 board. #sensors -v sensors version 2.10.0 with libsensors version 2.10.0 ensors w83627thf-isa-0290 Adapter: ISA adapter VCore: +1.60 V (min = +0.69 V, max = +0.77 V) ALARM +12V: +11.98 V (min = +10.82 V, max = +13.19 V) +3.3V: +3.28 V (min = +3.14 V, max = +3.47 V) +5V: +4.99 V (min = +4.75 V, max = +5.25 V) -12V: +2.94 V (min = -13.18 V, max = -10.80 V) ALARM V5SB: +5.08 V (min = +4.76 V, max = +5.24 V) VBat: +2.10 V (min = +2.40 V, max = +3.60 V) ALARM fan1: 0 RPM (min = 3515 RPM, div = 128) ALARM CPU Fan: 2235 RPM (min = 84375 RPM, div = 4) ALARM fan3: 1885 RPM (min = -1 RPM, div = 4) ALARM M/B Temp: +36??C (high = -96??C, hyst = +0??C) sensor = thermistor ALARM CPU Temp: +35.0??C (high = +80??C, hyst = +75??C) sensor = diode temp3: -48.0??C (high = +80??C, hyst = +75??C) sensor = thermistor vid: +0.725 V (VRM Version 9.0) alarms: beep_enable: Sound alarm enabled sensors-detect said: # Generated by sensors-detect on Thu Apr 13 01:30:04 2006 # I2C adapter drivers i2c-i801 i2c-isa # I2C chip drivers # Warning: the required module smbus-arp is not currently installed on your system. # For status of 2.6 kernel ports see http://secure.netroedge.com/~lm78/supported.html # If driver is built-in to the kernel, or unavailable, comment out the following line. smbus-arp w83627hf condor:~#i2cdetect 0 WARNING!
