I never even thought of low profile fans, Bloody hell! and there isn't any room in the bottom of the case for a dual rad, only a single... but if i got low profile fans like the ones that came on it, i'd be fine, i have an idea!
the case came with 3 230mm Low profile fans, i could mount two of them on the top, and have them blow a lot of cold air through the rad, and use the 2 corsair fans elsewhere in the case! *excuse me a moment while i feel great for a second from my newly found wisdom*
edit: in all honesty i didn't know they made low profile fans
