Also, how long have you been running you setup? I can't believe the h50 can handle triple rad like that! But it looks awesome nonetheless!
another user mod using 360 rad, working good
that mine 360 rad has no restrict flow - i can blow in to it without any hard, blowing into orginal 120 corsair rad makes me much harder. also adding coolant into empty loop - with older setup was very hard to make pump realy pumping cooland and air from loop - with new setup i rise rez little above loop and gravity does 50% and pump rest, few knocks and shakes of pump and radiator and everyting filled in and air out
also in pump rpm's i see allmost no drop - ive got 1520-1470rpm with clear tubbing and juce bottel res - and now with about 130cm tubbing, res and 360 rad - pump is runing about 1410-1440rpm - so i think she got not much harder to push
