Sensors output: Interpreting

[Mike McCarty]

Here is the output from sensors on my machine, and
I want a little help interpreting it.

$ sensors
w83627thf-isa-0290
Adapter: ISA adapter
VCore:     +1.51 V  (min =  +1.93 V, max =  +1.93 V)
...
V5SB:      +5.00 V  (min =  +4.76 V, max =  +5.24 V)
VBat:      +2.37 V  (min =  +2.40 V, max =  +3.60 V)
fan1:     3054 RPM  (min =    0 RPM, div = 2)
...
fan3:        0 RPM  (min =    0 RPM, div = 8)
M/B Temp:    +59°C  (high =   +63°C, hyst =   +55°C)   sensor =
         PII/Celeron diode
...
temp3:     +22.5°C  (high =  +120°C, hyst =  +115°C)   sensor =
         thermistor
ERROR: Can't get VID data!
alarms:
beep_enable:
           Sound alarm disabled

eeprom-i2c-0-50
Adapter: SMBus I801 adapter at 0500
...


Now for my questions:

What is w83627thf-isa-0290?
What is ISA adapter? (I know what ISA bus is.)
What is VCore? Should I be concerned it is out of spec?
What is V5SB? (5V Supply to USB?)
What is VBat? (Lithium CMOS backup?) Looks like it's out of spec.
What is fan1? (Power supply?)
Why is it "div = 2"? What does this mean?
I think I know what CPU Fan is, but why is it "div = 2"?
What is fan3? Why is it "div = 8"?
In regards to M/B Temp, does "high =  +120°C, hyst =  +115°C"
mean that the fan comes on at 120C, and continues to run'
until temp drops to 115C? (IOW, Onset is 120, abatement is 115?)
What is temp3?
What is VID data? Should I be concerned it is unavailable?
What is a EEPROM sensor? (I know what EEPROM usually means.)
What is SMBus? (Anything to do with SMP?)

Thanks

Mike

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
