Is it really needed?

Do I really need to replace a 120mm fan located on the top of the case blowing out?
I have 2 other 120mm fans, one intake and one out.

A less vague post would be helpful. What case? What are you trying to fix or improve?

Just wondering if I need to replace a bad one.

If your temps are fine then, no.

How do you know it's bad?

It turns out that it's not but was wondering about leaving it out. I had a high pitched noise coming from the PSU.
