Area around DVP642 or general dvd player



In the manual it suggests having 4" of space on the left/right/top. In my current configuration, I have like 1 1/2" on either side and probably 10" on the top in a cabinet… Is that just a manufacturers default measurement, or will this thing really overheat in my setup. To me it seems like there’s plenty of airflow around it??
