Depends on the type of pressure system you want. People have different opinions. Yours should be equal as it is which is a common setup. There’s three methods. All three are proven to be adequate with advantages and disadvantages. I’d leave it alone.

you have a neutral airflow setup, that is great interms of airflow, least you can do is that adding fans to the bottom if supported

I would remove it. I like positive pressure, and it’s stealing fresh air from the front that could be going through the CPU cooler.

people are waffling on about positive and neutral pressure as if that’s the most important thing here, it’s not
that top fan is exhausting fresh air that hasn’t gone through any hardware, essentially wasting a lot of the airflow of that top fan and stealing air from the CPU heatsink
yes, remove it

Disconnect that one fan and see if there’s a temperature difference.
TraumaMonkey
Flip it.

yes

On my last case, was very similar to yours.
On the yellow fan I used lowest fan RPM.

Generally I would remove the yellow highlighted fan, yes. Reason being that it disrupts the clear airflow path from front fans to the cpu cooler. They’re all in-line, but having that top fan sucking out air before it ever gets to do anything meaningful is counterproductive.
It may be the case that from a practical point of view the difference in temp isn’t big (hardly noticeable), but for any precise answers you’d have to perform your own tests to compare. No system is the same.

No. That setup is fine
