That's good to know.  Thanks for testing it.

What happens is the IOD takes the max temperature of the chiplets in the
package and presents that as the temperature of the package.  It works
the same way as it does in Rome (server parts).  For better or worse,
you just get the max temperature of the chiplets rather than the
temperatures of the individual chiplets.
