edit: I do not want to overclock the CPU and leave it as stock. The Hyper 212 evo is a great cooler but since my case doesn't fit a cpu cooler more than 157mm. The evo is 159mm. So i just left with this two corsair hydro series. So which one should i get? The price is $20 difference in singapore. And is it worth having two fans than one fan? Will I get lower temperatures like more than 5 degrees difference?
