LmSensorsSuperMicroPtThreeDdr
These are my notes on configuring lm_sensors on the SuperMicro P3TDDR motherboard. This dual PIII motherboard is found in the SuperMicro 6011H server.
In case you don't know what this page is for, lm_sensors is the linux software package for reading the sensor data (temperatures, fan speeds, voltages) that is available on many modern motherboards.

Manufacturer: Supermicro Product Name: P3TDDR
I found the correct modules to run by running /usr/sbin/sensors-detect. Modules:
i2c-viapro i2c-isa eeprom w83781d
Note that sensors-detect tells you to load the w83627hf module, which I think may exist in newer versions of lm_sensors. I didn't have that so I tried the w83781d module instead. Appears to work fine.
Here's the /etc/sensors.conf:

label in1 "VCore 2"
label in2 "+3.3V"

You should ignore the CPU2 temperature if you oinly have one cpu installed.
