2800 RPM good?

Hello, yesterday I built my first pc and everything is installed properly but if I start up a game (Fortnite for instance) my fans are spinning at around 2800 rpm and the temps go up to 78 degrees celsius.

It begins to make a lot of noise (I think that is a lot of noise for a pc but I can be wrong because it's the first time gaming on a pc for me).

I'm scared that the airflow isn't good enough, so my question is if it's normal or should I check the airflow/gpu?
