This issue seems symptomatic to Lenovo Legion laptops, as far as I know. Something seems to trigger the cooling effect. Mine also is a Lenovo Legion laptop.

Is your computer Lenovo by chance? I experience the same with my Lenovo laptop. I could figure out some tweqks to calm it down a little bit, but it’s still running quite often despite a minimal load.

I know, but I can’t ditch it entirely yet.

True. Microslop haunting. 🤭
