Why is it that the laptop fan is always very hot and emits warm air?

The task of the fan is to cool the processor. For this, of course, the warm air must be removed outside. The processor can get quite hot, especially in graphics-intensive applications.

It wasn't like that before! I downloaded an app and it has been so hot ever since!

Then this app must be quite demanding for the processor. Maybe a game that is very graphic-heavy?

No, it's not a game!
