My case is an nzxt h440, im running a i3-6100. A friend offered to sell me a h55 for $30, although i dont need it for an i3, I still think it might be worth it because its quiet, has better performance, and would give me opportunities for overclocking in the future with other processors. Anyway, what would the best mounting option be for the 120mm radiator? I would rather do it on the top, but if so, which side would the fan go on, and which way would it be blowing? Also, what fans should i purchase for this cooler? i would want ones to match my current nzxt fans.
