Good point, Mergatroid. I use the supplied H70 splitter to run the Corsair fans as case front intake on one fan channel, and the Uk3k's on the H70 rad each have their own channel. That way, you get full controller voltage, and if a channel (resistor) would burn out for some reason, you have another fan running as backup. I seem to keep very low temps as long as I have around >1800rpm, fanspeed through the rad. Under full load right now, 4 cores crunchin wu's at 42c, ambient 68f. Can't complain at all.
