Description of problem:

While this motherboard have lots of sensors, those aren't currently available on Fedora 18, as the Kernel driver is recent.

How reproducible:


Actual results:

Only the CPU sensors are available. It misses Fan, voltage and motherboard sensors.

Please don't backport those.  F18 will get 3.10 in a relatively short period of time.

This is fixed in the latest F18 update.
