Hello!

I have some basic questions regarding cooling a Haswell's i7 4770k, so I'd appreciate some help as I'm a bit stuck. I would very much like to buy an air cooler which would allow me to overclock to a stable 4.5GHz (1.25V) but while maintaining good temperatures.

As you may know, Haswell reaches very high temperatures and that's not exactly great about it.
So I'm trying to find a cooler which would change that, and I believe that Noctua NH-U14S is the way to go, but if there's a better option, I'd like to know about it.

Note: I own Corsair Vengeance high profile RAM cards (2x8GB 1600MHz).

I can move the memory cards to 2nd and 4th slots, increasing the selection of compatible coolers by a small ammount.

Cooling questions:

1.Noctua NH-U14S (dual fan setup) vs. Hyper 412 Slim, which one you'd prefer & why ?
2.Is there anything you'd recommend over these two ? If yes, please explain why as well.
3.Thermal compound, which one would you recommend for max. efficiency ?
4.Could you estimate "stable" temperatures for Hasswell (i7 4770K) overclocked to 4.5GHz at 1.25V ?
5.I've heard many people using the term "push-pull", could you please tell me more about it ?
6.Is it a good idea to turn 1 CPU cooler's fan to face the exhaust system fan ? (Top side system fan, 200mm)
7.If you answer all these questions, you're awesome and thank you.

Without any doubt I would go with Thermalright Silver Arrow or Noctua ND-14, but these are off the table due to high profile RAM.

Been thinking about a liquid cooling solution, but then I started reading reviews which made me change my mind due to huge ammount of problems, such as leaking / instability / noise / pump failures / short lifespan / overpriced / etc. and I simply cannot afford such risks, so I guess that's off the table.

Configuration:

Motherboard: Gigabyte Z87X-UD3H
Graphic Card: EVGA GTX 780
Processor: Intel i7 4770K
Memory: Corsair Vengeance 2x8GB 1600MHz
Hard Disk: Western Digital Caviar Black 2TB
Solid State Drive: Samsung 840S 250GB
Power Supply: Corsair TX750W
Case: Thermaltake Chaser MK-I

Thanks for the time reading this & respect to every constructive reply!

Cheers!

You are being paranoid about 'liquid cooling'. Get something like a Kraken X40 and you should be good to go :D
