Hi David. I have Asus P5B Deluxe WiFi AP Edition with Gentoo. Below is the content of my .gkrellm2/sensor-config sensor sensor_config_version 1 sensor sensor_float_factor 10000 sensor gkrellm_float_factor 1000 sensor "MB" "w83627dhg-9191-0290/temp1" 10000 0 1 0 sensor "CPU" "w83627dhg-9191-0290/temp2" 10000 0 1 0 sensor "AUX" "w83627dhg-9191-0290/temp3" 10000 0 0 0 sensor "FAN1" "w83627dhg-9191-0290/fan1" 10000 0 1 0 sensor "CPU" "w83627dhg-9191-0290/fan2" 10000 0 1 0 sensor "NONE" "w83627dhg-9191-0290/fan3" 10000 0 1 0 sensor "FAN3" "w83627dhg-9191-0290/fan4" 10000 0 1 0 sensor "FAN2" "w83627dhg-9191-0290/fan5" 10000 0 1 0 sensor "Vcor1" "w83627dhg-9191-0290/in0" 10000 0 0 0 sensor "Vcor2" "w83627dhg-9191-0290/in1" 10000 0 0 0 sensor "+3.3V" "w83627dhg-9191-0290/in2" 09900 0 0 0 sensor "+5V" "w83627dhg-9191-0290/in3" 15640 0 0 0 sensor "+12V" "w83627dhg-9191-0290/in4" 71000 0 0 0 sensor "-12V" "w83627dhg-9191-0290/in5" -74500 0 0 0 sensor "-5V" "w83627dhg-9191-0290/in6" -30950 0 0 0 sensor "V5SB" "w83627dhg-9191-0290/in7" 10000 0 0 0 sensor "VBat" "w83627dhg-9191-0290/in8" 10000 0 0 0 sensor units_fahrenheit 0 sensor volt_display_mode 0 Left side of these pictures shows Asus Probe II. I don't have Windows, so just googled for these. http://www.bugtrack.almico.com/file_download.php?file_id=197&type=bug http://www.bugtrack.almico.com/file_download.php?file_id=200&type=bug # TEMPERATURES MB 46.0C CPU 59.0C As you said I had to disable AUX TEMP. It shows high temperature and it doesn't make any sense. And based on the above picture, I renamed SYS to MB # FANS The motherboard has 6 fans (one for CPU and 5 for CHASSIS) fan2 detected CPU_FAN fan1 detected CHA_FAN1 fan5 detected CHA_FAN2 fan4 detected CHA_FAN3 CHA_FAN4 or CHA_FAN5 seem not to have sensors Asus Probe II only shows three CHASSIS fans No idea what POWER means, but seems to be fan3 Maybe it's because I am using ATX not BTX power supply unit # VOLTAGES I changed some numbers of 4th column, based on the above pictures. Now I get these values: Vcor1 1.22 Vcor2 1.84 Sometimes it changes to 1.83 +3.3 3.26 +5V 5.15 as Asus Probe II shows, sometimes it changes to 5.12 +12V 12.0 -12V -12.0 -5V -5.15 sometimes changes to -5.12 V5SB 3.30 VBat 2.82 Asus Probe II shows only one Vcore and the value is 1.26. Do I have to choose Vcor2 and adjust the value? Above picture doesn't mention -12V, -5V, V5SB, VBat. No clue what V5SB and VBat are, but maybe P5B users could ignore those.
