Install IPMITOOL or FreeIPMI and use those tools ( or super doctor ) to read sensors. You cannot control the fan speeds. They are managed by the onboard controller. You can choose one of several profiles in the bios but that is it. > My plan was to control the drive bay LEDs via software, so I installed > i2c-tools and ledmon packages.

The easiest way is to shutdown the system and unplug it for several MINUTES to discharge all the capacitors and insure everything resets. Then plug in and turn on again.
