Static pressure vs airflow fans – is there a real difference?
 

We are often told by online pundits that you have to use a static pressure fan for your heatsink or radiator, and that you have to use an airflow fan to intake or exhaust air from your chassis. In another fact-finding mission, I want to find out if the first claim is true – does it really matter if you want to put an airflow fan on your heatsink, not a static pressure model?
