Supermicro X7SBL-LN2 Sensors
The Supermicro X7SBL-LN2 motherboard has a Winbond W83793G, a Winbond W83627HG-AW, and an Intel core temperature sensors
The W83627 sensor is located in the back left corner of the motherboard, and is connected to the LPC bus. In general the sensors on the W83627are not used/connected, and the W83793G (below) should be used.
The W83793G sensor is located in the front middle of the motherboard near the front panel header.
Note: Getting technical information regarding the sensors from Supermicro is difficult.
Fan Control
It appears that PWM1 on the W83793 controls all fans at the same time.
Note: The configuration generated by pwmconfig (version 3.0.2-1.fc10) incorrectly seperates the FCFANS entries with a plus sign ('+'), which is not read correctly with the fancontrol script. Manually editing the configuration to use spaces corrects this isuue.
