push vs pull vs push-pull configuration on Cooler master hyper 212 evo ?
what is best ?

Generally the combo push-pull lining up with the airflow in your case.

Just the single fan in the default push config:

Wait, where'd you get that conclusion from?
The first post has http://cdn.overclock.net/3/3a/3afcca63_Graph2.PNG as result which puts "push" as worst option.
There's 25 pages to that thread though, does push come off better in the later pages?

I'll support a data driven conclusion over my guestimation any day though.

On the first page:
-----------------------------------------------------------
Push using 2000RPM Blademaster
Ambient Temperature: 23.2
CPU Temperature: 61, 57, 55, 59
Average Core Temperature: 58
Temperature Over Ambient: 34.8

Pull using 2000RPM Blademaster
Ambient Temperature: 23.3
CPU Temperature: 61, 57, 55, 58
Average Core Temperature: 57.75
Temperature Over Ambient: 34.45
-----------------------------------------------------------
So, about 0.4C difference.

-----------------------------------------------------------
Push using 2500RPM Sickleflow
Ambient Temperature: 23.5
CPU Temperature: 61, 58, 56, 58
Average Core Temperature: 58.25
Temperature Over Ambient: 34.75

Pull using 2500RPM Sickleflow
Ambient Temperature: 22.6
CPU Temperature: 58, 55, 54, 55
Average Core Temperature: 55.8
Temperature Over Ambient: 33.9
-----------------------------------------------------------
About 0.8C difference

"But if someone buys a brand new Hyper 212+ or a Hyper 212 Evo, I would suggest just using the one fan, as shown above it is pretty close in temperature."

The pull config appears to be ever so slightly better than the push, but not enough, to my mind, to really worry about.

i have phantom 630 all stock fan and the HDD Pivot will be aerocool shark fan 120mm
how bout that ?

But there's also this:
Push/Pull using CM 2000RPM Blademasters (without a rear fan)
Ambient Temperature: 23.0
CPU Temperature: 59, 56, 55, 56
Average Core Temperature: 56.5
Temperature Over Ambient: 33.5

Push/pull is 0.95C below pull.

Pull > Push/Pull > Push

Really? I would expect a linear progression with a change of prop. There's only a single data point for each setup though.
Unrelated, were these fans chosen for different . . . . blowing techniques? That might explain the change in preferred setup.
I'm also wondering what that rear fan was doing that the temp was higher for w/o
I'm going to have to read that thread now. Damn 😛

For Abdallahmgz: The temperature differences are small enough that unless you're really pushing your OC it should not affect your system.
And if you are pushing your system that hard you may want to consider water cooling.


Edit:
From that thread:

Those pull fan results are very very interesting -- quite the opposite of other heatsinks. And you had consistent results: both fans produced better cooling on pull alone than with push/pull or push alone.

I'm missing something, aren't I.

that will bring alot alot of dust
