i can hardly imagine what would be more quiet than my hyper 212 even the fan on my PSU is louder...i can't hear it even under full load and i run an highly overclocked FX-8320 under that thing... anyway

the rock 3 sure does look a little better tho!
But my guess is that the OP didn't realised his CPU wasn't meant for overclocking and his money would be much better spend somewhere else on his system like a new GPU or more RAM or an SSD as stated earlier...
