Hi folks.
I believe I have solved a problem that has plagued me for a couple of weeks. Sensors was reporting FAULT for the system temperature. See the bottom of the message for how I think I have solved the problem.
First, my setup:
===============
AMD Phenom X4, 4GB RAM DDR2 800Mhz, MSI K9A2GM-FIH Mobo
Ubuntu Hardy Heron 8.04
2.6.24-19-generic #1 SMP x86_64 GNU/Linux
sesnsors output(NOTE the FAULT reading in the last section
=======================
kdt at kdt-lnx0:/etc/init.d$ sensors
f71882fg-isa-0600
Adapter: ISA adapter
3.3V: +3.36 V
Vcore: +1.26 V (max = +2.04 V)
Vdimm: +2.21 V
Vchip: +1.74 V
+5V: +5.42 V
12V: +11.50 V
5VSB: +3.86 V
3VSB: +3.36 V
Battery: +3.28 V
CPU: 1411 RPM
System: 0 RPM ALARM
Power: 0 RPM ALARM
Aux: 0 RPM ALARM
CPU: +39.0?C (high = +85.0?C, hyst = +81.0?C)
(crit = +100.0?C, hyst = +96.0?C) sensor = transistor
System: FAULT (high = +85.0?C, hyst = +81.0?C)
(crit = +100.0?C, hyst = +96.0?C) sensor = transistor
Now, the sensors.conf (relevant portion)
===================
chip "f71882fg-*"
# Temperature
label temp1 "CPU"
label temp2 "System"
ignore temp3
# Fans
label fan1 "CPU"
label fan2 "System"
label fan3 "Power"
label fan4 "Aux"
# Voltage
label in0 "3.3V"
label in1 "Vcore"
label in2 "Vdimm"
label in3 "Vchip"
label in4 "+5V"
label in5 "12V"
label in6 "5VSB"
label in7 "3VSB"
label in8 "Battery"
# never change the in0, in7 and in8 compute, these are hardwired in the chip!
compute in0 (@ * 2), (@ / 2)
compute in2 (@ * 2), (@ / 2)
compute in3 (@ * 2), (@ / 2)
compute in4 (@ * 5.25), (@ / 5.25)
compute in5 (@ * 12.83), (@ / 12.83)
compute in6 (@ * 5.25), (@ / 5.25)
compute in7 (@ * 2), (@ / 2)
compute in8 (@ * 2), (@ / 2)
I finally found a data sheet for the F71882 chip, which is used on this mobo:
http://www.datasheet4u.com/html/F/7/1/F71882_Fintek.pdf.html
Now, look at the sensors3.conf. It's saying to use temp2 as the system temperature. HOWEVER, in the data sheet it refers to line D3 as (System). Hmmmm... I set the sensors3.conf like this:
=================
# Temperature
label temp1 "CPU"
ignore temp2 "T2"
label temp3 "System"
BINGO! Now I get a reading that occasionally changes and makes sense. Hope this helps anyone else in my situation.
Thanks much to the volunteers for their hard work on an outstanding and open product. I seriously doubt I would EVER have found this using closed-src.
