My 2015 mbp 15" i7 runs at like 65/70c all the time with only like maybe 3 windows open and the fan is always at 2k+. If it does get overly hot just doing normal tasks I will get a app to throttle it at certain times if I need to. I don't need max performance with turbo boost if I'm just browsing the web. I never really ran temp monitors on my laptop until yesterday and saw it on the mbp.My 2020 air is much cooler on my lap than my 2018 macbook pro (i7). Even though the processor on the air gets much hotter (hitting 100C a lot).
