There are frequent questions regarding the Hyper 212+ and whether or not push pull is worth it for the heat sink, so I did a more complete test to find out.
There are also frequent questions regarding whether or not positioning the heat sink vertically would affect performances, so I tested that too.
Note:
These tests are done using Prime95 at 20 minute intervals. The graphics card was not under load during the tests therefore results may vary.
Also the case used was a CM Elite 335 with the rear and front fan grills cut out.
The testing is done using a i5 760 overclocked to 3.8GHz at 1.353V using IC Diamond TIM
The wiring may seem like a mess, but it is the best I can do, all of the extra power cables are up top and there is a hole where the fan in the 5.25" bays blow cool air into the case
Testing Results
All temperatures are recorded in degrees Celsius
Horizontal Tests

The push/pull sickleflow was best since it had the highest cfm, but the push pull blademasters are also really good. 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.
As for the being horizontal or vertical, either is good but you would need ball bearing fans because when I tested it, the blademaster was vibrating audibly. However with the cooler vertical, it is best to have either a gaping hole up top or to have a faster fan than the ones on the cooler.
Questions and suggestions are welcome!
