^ all of that has no real validity. Those closed loop cooler(CLC's) are nothing but piles of junk with a fake "watercooling" tag on them.
if you're going watercooling, invest in an entry level kit like an XSPC rasa 240/360 kit...better yet, head down to teh watercooling sticky(in my sig) and maybe pop down to the closed loop coolers section to be better informed of these so called liquid coolers.
there are more reasons for not getting a Hxx series
If you really need something cheap and is also good should you go for that overclocking agenda , the Hyper 212 evo is right up your alley. Beyond that, there's no real reason to move to an expensive and crappy cooler thats outperformed by a cheaper air cooler.
btw, you haven't mentioned anything about your full system specs...
