I'll just leave this here.

"Most third-party applications are reporting the processor temperature
fairly accurately.
Because reports can sometimes show erroneous data, download
Intel® Processor diagnostic Tool to test if your processor is working correctly."
Fairly accurately = rough indication.
Erroneous = downright wrong.
I'm not saying that Intel isn't more accurate with temp reporting than AMD, but to try to brush the issue off entirely and act as if any problems are AMD's fault is misleading. I'm sticking with my original statement: third-party temp monitoring is sometimes subject to strange behavior and incorrect readings no matter which manufacturer made your components.
