The guy who originally posted that claims and screenshot has been creating a bunch of clickbait articles for some time, a few people have questioned the validity of his claim or at least wondered if he has a faulty unit.

For example here is someone trying to replicate this but ended up seeing the complete opposite results:

"Here’s the m2 MacBook Pro 13 rendering 8k canon raw footage for 15 minutes straight with no fans, no high temp, no anything." - https://twitter.com/every_daydad/status/1542534316433068033?...

I see the Twitter thread has already been regurgitated as an article elsewhere.

Do we know the junction temp of these chips? How are they not shutting off at 100c?
