when you see low temps in the 30...(like my system). there using water cooled h100/h80 or a 140mm brick of a cpu cooler and a lot of case fans..i have an antec 100 and i have the two fans blowing out..you can see if it case flow issue or see if yuor temps drop if you take the side panel off and watch your temps.
great, thanks for the reassurance.
I am using a haf 912 with two front intake 120 1 side intake 120 1 rear expel 120 1 top expel 200
but i am pretty sure my non-modular psu's pile of unused cables is mucking up some airflow
