Looks reverse air-flow to me.
Now that the cards are available go to the website and compare the GTX970 and GTX770 with ACX.
The fan spins CLOCKWISE, but the more I stare at it I don't understand why anyone would think it pushes air towards the mount.
Both the previous ACX fans and the new ACX 2.0 fans spin counter-clockwise. The blades have a different sweep, but they spin the same direction.
You have to look at the cross-section of the fan blades (not the direction of sweep away from the center axis), that will tell you which way they spin and push the air. Which ever side of the blade is concave or "scooped" is the side that pushes the air away. The EVGA ACX 2.0 blade cross-section is quite flat, but there is a very subtle curve to it. If you look closely you can see the one side is curved outward (convex) like an airplane wing, which will effectively help pull air in while the other (scoop) side pushes.
Fans are much more efficient at moving air via pushing/blowing it rather than pulling/sucking it. You can put your hand some distance away from a running fan and still feel the air blowing, but you have to put your hand very close to the blades to feel it sucking.
100% these are counter-clockwise spinning fans.
