Overheating framework 13

Just got my i7 13th gen Framework 13, and I’ve been noticing under heavy single threaded loads (say, unzipping a file,) the fan spins pretty high and the cpu gets pretty hot. This, to me, feels like a bad thermal paste application. Is it worth replacing the paste? Or is this just how modern Intel CPUs are? My last laptop was an AMD 4800H so I’m not so hip to the new intel nonsense.

edit: Browsing i7z, it looks like it’s mostly cores 4 and 5 (logically 6 and 8, because hyperthreading) seem to be the most problematic.
