From what I've read push and pull has been proven to provide only marginal performance boost .in the case of single fan and 212, pull provided better performance (though, honestly can't remember if it was the + or evo model)
It may just be with the Hyper 212, which is a fairly slim heatsink, I have read that when the fans are too close (within 1 to 1.5" or so) the effectiveness drops, when I used to do it I had a massive heatsink, Sunbeam CR-CCTF, and I was using insane fans (Ultra-Kaze's) with it, I had really good results
Right now I have a 212+ in push/pull but using PWM fans, though I never overclock...the aftermarket sink was for silence not cooling
