2 fans (push/pull) on a 212 EVO gives very little benefit. A degree or two at best.
The single stock fan is fine.
But if you must, they both need to blow the same direction...towards the back of the case.
So would you say the best thing to do would be to buy a single Corsair SP fan to replace the stock cooler master fan and then replace the chassis fans with corsair AF fans.
I'm saying use the stock CM fan that comes with the cooler. I have a 212 PLUS (the previous model) with only the original fan.
In an 84F(29C) room, at 100% Prime 95 load, the max temp I see is ~69C. Idle temp is ~39C
For the other fans, more is not always better.
