Best fans for a H100i push/pull config?

Trying to find fans that will disapate heat as fast as possible for my i5-3570K using an H100i. I'm thinking about getting Noctua NF-F12s, but I want to hear Tek Syndicate's voice before I make a choice. Thanks :D

Either works fine, I would do a pull for easy cleaning but that is really it.

NF F12s are fantastic fans. Look into Scythe Gentle Typhoon 1850 RPM fans, too. They are one of the go-to fans for radiators.

Cleaning isnt a big concern for me. I just want the CPU to stay as cold as possible, trying to get a 4.5GHz overclock if I can. Forgive me if that seems unreasonable lol.
