Just get Hyper 212+ and add another xtraflo and rock on, my friend has the same setup, idle is around 40s and load is around 65-68c, a tad higher than Noctua U12P. Only issue is applying Thermal Paste.
Else get D14 for 4.8k.
Also Cooler Master V6GT is there @ 4k, not as good as noctua coolers but good none the less.
I am not suggesting Thermalright coolers cause with price of the fans they come to 4.8k(3.8k cooler only) and at that range they are mauled by NH D14.

Overclocking is no Hurry.. Wait for Good Products if stock is not there at present.
In Real Time major applications.. you find Nothing boost between OC'ed and No OC system. Even in Gaming also..hardly 1 or 2 FPS if it is GPU bound Games.. If it's SLI or Fire setup you may get reasonable Boost in higher Resolutions... OC is Exclusively for Benchmarks not much for Real-World Applications apart from Encoding Jobs..
In my opinion...A70 or V6GT both are not worth at present.. Wait till Oct'ber, Seems to be New coolers are being launched..
Noctua is good But they really have bad clearance issues with certain models.. still they perform Top Notch..
That's my opinion...
He is getting Gskill sniper,
ALL coolers will fit. Plus he has CM690II.
