Disagrees with Intel Power Gadget about osx-cpu-temp HOT 3 OPEN

If you're still able to reproduce this, it might be worth testing the stock powermetrics command-line utility which (AFAIK) is the closest you can get to getting these values from the SMC directly. Perhaps Intel's Power Gadget is doing something special to get more accurate results?

sudo powermetrics --samplers smc -i1 -n1 will get a single (-n1) sample from the SMC (--samplers smc) after waiting 1ms (-i1) (normally it samples continuously every 5000ms)

If you can reproduce it with powermetrics, then we know the cause is not osx-cpu-temp but rather what the SMC is reporting.

I can +1 and say disagrees with Fanny Widget for macOS as well. Seems to be reporting around 6°C lower.

I tested it against powermetrics, it was reporting around 99°c, meanwhile osx-cpu-temp was reporting around 50-60°c. The 99°c number is believable, the MacBook was working hard and 2015 MBPs are notoriously hot, even with fresh thermal paste.
