Xigmatek Dark Knight II Night Hawk

I am building a Mini-ITX build and I plan on using the Dark Knight II Night Hawk Edtion and I was wondering if anybody using it has any temperature benchmarks. Also I was wanting to know what the ram clearance is when using this cooler. Lastly does anybody know how high of an overclock I could get with a 4670k?

get some low profile ram nothing with big heatsinks like corsair vengence and you will be fine for ram as for cooling it performes around the same as a H80i I believe so look up some temps on that cooler and it should be similar.  For an oc depending on the motherboard and the "silicon lottery" probably 4.2-4.5ghz I would guess.
