Hmmm, I have 2 pumps in a single loops with three rads and I get better temps on everything than when I had 2 loopsand this is with only 2 fans on the 480, 1 fan on the 240, 3fans on the 360...I am using one d5 and a D4, I am cooling the cpu, mosfets, NB/SB, and dual GTX 295's....:shrug: I decided to get the HK 3.0 LT for the lower Pressure drop and the temps are very close! Could the unpolished base be the temp difference between the KL 350 and HK?
