I'm not following... the 212 is a heatsink with horizontal fins isn't it? So you should have one fan blowing through the fins and it doesn't really matter which direction it is blowing. As long as air is being blown or pulled over the fins and heatpipes it shouldn't be a problem.
Blowing downward is bad, it goes against the natural airflow of the case.
OP the fan is removable on the 212 EVO. Take it off, move it to the other side of the cooler so it blows upward and reinstall it. Its a simple change.
See, when I read blowing downward my automatic assumption is towards the motherboard. I'm sort of ancient that way I guess. Towards the motherboard is good. Now when someone says blowing down and they mean inside the case, well that doesn't quite register either because in that case the fans shouldn't be blowing up or down, they should be front to back, blowing right into that big fan that sucks the heat out of the case. I don't even know how you mount a fan to blow down. That is very strange to me and whomever thought that was ok to design a heatsink in which that can happen is obviously insane.
