Linus once said that you need pressure fans in areas witch are blocking the air flow of the fan, in this case 212 evo fins are blocking free air, so thats why im looking for sp series of noctua because, they well rated, they give good air flow (pressure) by keeping low noise also i watched this video https://www.youtube.com/watch?v=gXAFYNE7Cl0
and if it will be too noisy for me, i will turn down speed in motherboard bios setting, but i think it wont be, because cooler master tx3 fan was acceptable for me almoast 2 years and still is, tx3 is just smaller than 212 evo witch i first wanted but wasn't able to buy, cuz of case limitations.
as well for airflow the best one i've found was this one - beast fan http://noctua.at/en/nf-s12a-flx.html#.VlIFC-J3K00 107 cubic metres within one hour only at 1200rpm with ~18dB sound - BEASTLY FAN
