I was looking into watercooling in the ncase m1 and I am planning on using an EK PE 240mm radiator on the side which according to EK's site has a cooling capacity of about 260 watts at 1500 rpms with their vardar fans. I was wondering if adding an additional 120mm slim radiator with a slim fan to the loop would enough of a difference to warrant doing. Does anyone have experience or insight regarding this?
