Ok so my first is for nh-d14 and nh-d15 cpu coolers. I know the fans should point in the same direction for air flow facing the back exhaust fan on the case and one fan should go in the middle (unless someone thinks differently). I want to know if the second fan should go on the back pushing air towards the middle fan, or should it go on the front pulling air from the middle fan?

My second question is about the Noctua NH-U9B SE2. Should the fans be facing the same direction for air flow towards the back exhaust fan in the case? Or should the airflow from both fans be facing inwards towards the cooler?
