How do I determine my fan's airflow direction?
When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:
For intake fans, the sticker should therefore be towards the inside of the case, whereas it should be towards the outside of the case for exhaust fans.
