Corsair H100i - fan spin direction?

[Siberian]

So I just got me Corsair H100i. It says to install the fans so that they they pull air in through the radiator, but there is nothing indicating their spin direction. Anybody know?

To give you a reference, the direction of air flow on this fan is away from you.

Hook up a fan and turn it on to see which way it blows.
