(it nearly fits tho)
At first i want silent fans but that is a no go because of the high density and fin array of the radiator, also the pump is very weak it puts only 12 gallons a hour that's only 48l/pm roughly.
So i would highly suggest to mount the radiator in the top of the case pushing air out, if you can run it in push/pull with high static optimized fans and you will get good cooling otherwise in only pull or push it simply will not cool that much better than most high end air coolers.
pushing air is always better than sucking air from it... i don't know how people can say pulling is better than pushing because i tried everything from pushing, pulling and push/pull and the last gives me the best performance, i saw once on the internet that was from Linus Techtips that it does not matter if push or pull -_- i went like REALLY? i tested that and under full load i got 5/8c difference.
Also he is raving about the Noctua fans, the NF-F12 well i can tell you this that my Cooler master sickleflow blue led perform much better, more quiet and has better static pressure and for the price of one Noctua i can buy almost 4 Cooler master fans
Don't get me wrong that i think Noctuas are not good because Noctuas have mush better build quality but in my opinion they are way overpriced, i saw several reviews and the Noctuas perform very good but the Sickleflows are much more for your dollar
It all depends on how cold the air is what you push through your rad since that is the most important factor because, you can have the most powerful fans with the best radiator but if you pushing warm air through it you will never be able to keep it any cool.
Also like dmfree88 said, make sure you have an powerful fan as your exhaust that sucks warm air out of your case.
