Didn't they stop doing that?
No, they havn't. The Ryzen1000x's had a 20c offset, the Ryzen2000x's have a 10c offset. It dosn't matter to be honest as long as peeps realize which is the actual temp and which is the offset temp. The only reason it's there is to bring the cpu fan speed up earlier during the heat up stage, in other words it forces the cpu to believe it is hotter thaan it actually is.
