Best CPU cooler that won't block RAM slots?

[stepit]

What is currently the best Air CPU cooler within $100 budget that would fit Antec 300 and not block any RAM slots. It also must be as quiet as possible. I intend to overclock.

I'm using MB GIGABYTE|GA-Z68A-D3H-B3 Z68 1155 MoB and i5 2500k.

Not sure how similar your board is but I have an ASRock P67 Extreme 4 board with all 4 RAM slots filled and a Noctua NH-U12P SE2 fits in there fine
