I come from an industry where I deal with the airflow in and out of things. Your screen will lead to slower airflow which will get worse if leaves, debris, etc. get stuck on the screen. This can and will lead to additional heat in the IC, but frankly without knowing what else you have done under the hood, it is tough to say how much. That is something a heat gun could answer. If you are in stock mode and haven't done anything else, the heat increase should be minimal and should not affect your performance...SHOULD being the operative word.
