Do I need a case fan?

Hi guys! So I was wondering if I need a case fan for this PC.

My case currently doesn't have one and I was wondering if I need one?

Typically, I would say yes, at least one for intake and one for outtake, if not more. Would be nice to know what case you have regardless. Also, I would do some research to make sure that CPU will work out of the box with that board as it is flagged for compatibility. Could save some hassle later.
