The Supermicro -F boards have a BMC onboard which monitors and controls the sensors. You should be careful not to change the configuration of the sensor chips so you don't interfere with the BMC control and monitoring.
You may want to look at the "bmcsensors" module for lm-sensors or use an IPMI utility directly ("ipmitool sdr elist" or "ipmitool sensor")
However, I would recommend the "coretemp" module so that you can see actual CPU temp. Supermicro policy is to report CPU temps as only green/yellow/red. Very annoying.
Phil P. -- Philip Pokorny, RHCE Chief Hardware Architect PENGUIN COMPUTING, Inc Hi,
I am trying to get fan control running on a Supermicro X8DTH-6F motherboard[*]. Supermicro tech support provided me with a specification file for the hardware monitor chip, a Winbond W83795AG. I have built and installed lm-sensors 3.2.0. I'm trying to understand how to convert the specifications into a good lm-sensors config file.
Here's an excerpt from the specifications file:
â
Windbond W83795AG, Slave Address=0x2f (0x5E in 8-Bit format) ============================================================= Fan1 Fan Speed, Offset 0x2e RPM = 84375/Data CPU1 Voltage, Offset 0x10 Voltage = Data* 0.008
CPU2 Voltage, Offset 0x11 Voltage = Data* 0.008 +5V Voltage, Offset 0x1f Voltage = Data* 0.008 * (40/10) â
If I understand this at all, to get the fan monitoring to work, I want to assign offset 0x2e to fan1, and add a compute line for fan1 like so: "compute fan1 84375/@, @*84375". Does that make sense?
Thanks!
