[ELI5] Why is decreasing a fever considered good when that is your body fighting back ?

As I understand, the magic number is 40C over which proteins change, so decreasing it below 40C makes sense.

But why are doctors advising to decrease even when you have like 39.3C
Isnt increased fever how your body fights back. So by decreasing fever Im hindering my body.

The body basically has a fever to try and "cook up dead" the stuff that shouldn't be in your body, problem about that is that you also get cooked in the process. The body tends to overdo the whole thing too, so there's the chance that you'd end up dead along with whatever decided to get in you.
