Try disable turbo and search around there is an utility that keep no turbo and using hours still 50 degree.

I am not associated with that guy. In fact I bought one for even my macmini. Get my m1 macmini to avoid all these hot air.

If you run biotcamp windows has registry to disable that and also system setting to limit to 99% (but seem still hot) for my playing with Vr and fs2020 using external egpu.
