the EX-series has 20 fins per inch.. and works well with 1200-2000 rpm fans..
i'd have to disagree with your statement "Radiator with 19 fins per inch is not
optimized for slow speed fans.
." like my Black Ice GTX 360 (20fpi) works well
with the Swiftech Helix 120, GT-15, Corsair SP120 (Quiets), Noctua NF-P12
even with the thicker core still was satisfactory in cooling..
so from my experience, i can say the EX will have the same experience, but
due to the thickness will not have as much headroom as the thicker counterparts.

this was all in the same case, pump, tubing and routing. just the rads were changed.
same Swiftech Helix 120 fans were used in all above runs...
