[mythtv-users] OT: Output from LM_Sensors - Something hosed?

[Douglas Wagner]

I'll try to keep this short:

I've got a brand new Antec SmartPower 2.0 500 Watt PS in a new case for my
PVR (less than a week old).  I've just re-installed my myth box to Fedora
Core 6 (64 bit) and setup LM Sensors.  My prior install had LMSensors up and
running but everything was alarming, I'm now trying to get rid of the alarms
and actually have something that would notify me when a PS was going out.

The following is the output from my LM_Sensors:

[root at ghost ~]# sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:
             +36°C

it8712-isa-0290
Adapter: ISA adapter
VCore 1:   +1.49 V  (min =  +1.42 V, max =  +1.57 V)
+3.3V:     +3.22 V  (min =  +3.14 V, max =  +3.47 V)
+5V:       +4.97 V  (min =  +4.76 V, max =  +5.24 V)
+12V:     +12.29 V  (min = +11.39 V, max = +12.61 V)
-12V:     -27.36 V  (min = -27.36 V, max =  +3.93 V)   ALARM
-5V:      -13.64 V  (min = -13.64 V, max =  +4.03 V)   ALARM
Stdby:     +3.92 V  (min =  +4.76 V, max =  +5.24 V)   ALARM
VBat:      +3.25 V
fan1:     3590 RPM  (min =    0 RPM, div = 8)
fan2:     1308 RPM  (min =    0 RPM, div = 8)
M/B Temp:    +38°C  (low  =   +15°C, high =   +60°C)   sensor =
thermistor
CPU Temp:    +40°C  (low  =   +15°C, high =   +60°C)   sensor =
thermistor
Temp3:       +93°C  (low  =    -1°C, high =  +127°C)   sensor = diode
vid:      +1.500 V

Core Temp is fine from the AMD Thermistor
VCore is fine (1.5 +/- 5%)
VCore2 is turned off (Constantly reading 0)
3.3V is within spec
5V is within spec
12V is within Spec
-12V is WAY outside spec
-5V is WAY outside spec
Stdby is outside spec
The rest should be ok. (Temp3 is set to 93c, it's 127c when sensor =
thermistor...and it doesn't vary...so I assume it's probably either inactive
or not calculated correctly)

So my worries are -12v, -5v and Stdby.  I read somewhere that the negative
rails are purely crap these days and you shouldn't really worry about them,
which brings me to Stdby.  Stdby seems to be set to 5v +/-
5%...unfortunately at 3.92v it's well below that standard...I can't find
anywhere where 3.92 is an acceptable value for Stdby.

Is this something I should be worried about?  I can set the alarm to a lower
threshold, that's not an issue, but I don't want to do so if I've got some
kind of power problem already.
