I see what your saying. In my case the more exhaust areas lower the case temps i.e. (cool) intake fan air would blow across lower half of mobo (my P5N-E southbridge produces far too much heat) and push it out instead of leaving hot air to circulate.hp7909 said:Have mine on, assuming that off would affect airflow i.e. (cool) intake fan air would blow straight out the other end![]()
