Wait!! I'm pretty sure of this, barring the Sunbeam Core Contact Freezer.
Noctua-NH-U12P.
You really have a choice, though. I'm pretty sure that hands down, the IFX-14 has the lowest thermal resistance of all these:
IFX-14
Noctua-NH-U12P
ThermalRight Ultra 120 Extreme
OCZ Vendetta 2
Xigmatek
But the problem with it is its size, and how you plan to mount the fans. I had a great idea of mounting it with the widest surface facing upward, sticking a piece of foam board between the the two sets of fins, building a foam-board duct around the whole thing, and pulling air through it with a 120mm case-mounted exhaust fan.
I can even see using a TR Ultima 90 for its size and weight.
The reason that I can be flexible about this, is the incredible scalability of over-clocks with the E0 Wolfies at voltages matching the retail-box spec.
