which would be better for an i5 3570k at 4.5ghz overclock or in general? I've yet to find a good comparison or one at all online comparing these two. Hoping on an off chance somebody here has experience with both or one of these heatsinks. I've been wanting an all-black heatsink for aesthetics.


For either, I'd be replacing the stock fan for push-pull black cougar vortex 120mm fans(part of me is wary of the rubber plugs holding the fans on the Dark Knight, but never read of being a big con online), or a good yet quiet LED fan, still not sure if I'm going green,red, or blue for pc theme in terms of lights.
