If you're buying the Pi4 then why not go for a Pi5, there's very
little difference in the price.

I've run two Pi4 systems without heatsink or fan for a very long time
with no issues at all.  I've just looked at one of them, it's been
running at least since May 2023.  As I understand it anyway the
system will simply slow down if it thinks it's getting too hot.
