Given the surge in popularity of quad socket AMD systems, sensor information is below. I estimated the resistor values for +5V, +12V, will confirm later. Tested with a Supermicro H8QGi-F system.
assumes w83795 module is built and loaded.
For supermicro H8QGi-F (and like variants), add the following to /etc/sensors3.conf
Example output from 'sensors' command, idle:
(note the min, max values are just the default programmed thresholds considered within norms -- these aren't the min/max observed. charset wasn't set to UTF-8, so degree C is garbled)
Example output from 'sensors' command, folding load on watercooled system, a few degrees cooler than usual as it's not doing a -bigadv:

However, when I feel the exhaust, the air seems only slightly warmer than the surrounding room temperature (~27C). So while the machine is running, I decided to use the on-board sensors to monitor temp under different operating conditions to see if I truly do have a problem.
