I cant really decide between these three coolers, i want to overclock but keep a quiet rig or at least cooler but not very sure about it when it comes to these so give your recommendation.
Ill be using a 4670k
ROCK 2-
Its the only air cooler i would like but not sure how it would compare against the AIOs.

Seidon 120XL-
I like the look of the block from their seidon series and its the cheapest of the three.

Seidon 240M-
Just a larger version which i assume would allow me to slow down the fans the most and keep temps down.
