Is there a real huge difference between these other than the h70 having a thicker radiator and no fans? They're the same price so I was just wondering what one would I be better off going with? I'm going to be putting it in a Bitfenix Prodigy at the rear so I'm thinking the h60 as it is thinner than the h70. I will only be overclocking the 3570k to around 4ghz.
