I have an NZXT phantom 410 case and im running an fx-6300 and an r9 280 in it with a 550w power supply. I was wondering whether or not i could get a liquid CPU cooler with dual fans and take the stock top fan off on the top of the case to make room for a dual sized (2 fans) radiator or if i should just get a single sized radiator (1 fan). I am also wondering if I should get a larger PSU for a liquid cooler? please help me
