Cheap i7 OCed watercooling

[misho]

OK, so thicker rad = better, I am going to go with a 3x120mm rad, (36cm), because I am going to put it on top of my case,
sitting on its side. Like this:: . Is this going to be a problem for the big pump to push all the water up like that? And I want to get the thicker rad because thicker = better


Edit:: What is better: Black Ice GT Stealth 360 OR Swiftech MCR320-QP?

I am looking to maybe get one of these
