    Does OC Panel report Ryzen 1700X/1800X temps accurately, or with a +20 C offset?

    I read that Ryzen 7 1700X and 1800X CPUs appear to add about a +20 C offset to the actual temps at the Tctl sensor (die-to-heat spreader junction). AMD purposely does this so the fan control curves will act more aggressively to get out in front of rising CPU temps in response to increased processor demands. But this has freaked out users who see high temps at idle (e.g. 40-50 C) through software monitoring. This is my understanding of the situation so please correct me or add to the post with additional info.

    My question: is anyone using OC Panel I or II on a build with Ryzen 7 1700X and 1800X CPUs, and what temps does OC Panel show? Are they accurate (i.e. no 20 C offset)?
