I recently obtained a Supermicro X7SPA-H motherboard for a NAS project,
loaded Fedora Core 13 on it ('mdadm' in FC 14 acted very
flaky...'unreliable' compared to FC 13), and developed a "local"
LM_Sensors configuration to share.
After referencing the configuration on the LM_Sensors.org web site
(http://www.lm-sensors.org/wiki/Configurations/SuperMicro/X7SPA), I came
up with a very slightly different configuration.
- I found no need to set limits on 'in6' since the limits shown in
"sensors" and those shown in Supermicro's "sdt" are the same and seem
"reasonable".
- I made very minor changes to naming certain inputs.
- I ignored "temp 3" since I could not easily correlate that to anything I
found meaningful or 'reasonable'; it's temperature reading always seemed
much lower that CPU diode or System thermistor readings, sometimes by
almost 50 percent less. Supermicro's "sdt" utility under Linux only
reports 2 temperatures and they correlate closely to 'temp 1' and 'temp
2'.
My "local.conf" file is based on studying the BIOS (Supermicro version
1.0c), the Supermicro SuperoDoctor utility [Supero Doctor II - Linux
version 2.73(101019)] for Linux, and the output of "sensors".
Note: The only 'adjustments' in Supermicro's Version 1.0c BIOS alter the
CPU overheat alarm ('early' or 'default') and the 'Fan Speed' (4 settings
controlling PWM percentages 100/70/50/30) applied to both 4-pin fan
headers (silk-screened: CPU Fan, SYS Fan) on the motherboard.
