ekwb recommended the EK-CoolStream SE 240 (Slim Dual) radiator but i thought i could get a better one for the same price. on ek's cooling configurator it said the system would be 27c at idle while mine is 32c. i bought the alphacool nexXxos xt45 because it seemed better in every way because it had more fpi, and it was a full copper radiator. was i wrong, or is ekwb's estimate incorrect?
