Are these intake fans or exhaust fans?

Yes. When you install them you choose the orientation, which dictates the flow direction. They will flow "through" the arms that hold the hub, so if you want to mount it as an intake fan the NZXT logo you see in the image will be facing out of the case.

How does the NZXT F120 RGB Core Fan enhance cooling performance?

The fan features a refined hub and blade design that pushes air through your radiator for enhanced static pressure while still providing powerful airflow.

What is the fan size and thickness of the NZXT F120 RGB Core Fan?

The fan size is 120mm and the thickness is 26mm.
