Hondacity,

nice post so far, for flow rate you said the koolance is only good with 2 pumps? I thought the general consensus now was flow rate (as long it was not much below 1gpm) was not that important, I am looking at getting one of these blocks as I move to i7 and if a 2nd pump is really necessary to get the most out of the koolance then that changes the price equation quite a bit. Have you tried the koolance with and without the 2nd pump on (if so what temperature differences did you get?) .
