Not really, because most of your heat removal will still be through convection. Even if you have zero _forced_ airflow (fans, etc), you will still have airflow, due to hot air decreasing in density, and flowing upward, which is then replaced by cooler, denser air, and so on and so forth.
As BB2K said, heat removal through radiation is not terribly relevant here on Earth, in most cases.
