For enhancing cooling/better temps, bigger rads always > then more flow. No need to concentrate on pump/coolant flow.
I was just concerned that even with my triple rad the water isn't staying in the rad long enough for the fans to cool it off as my temps could be a few degrees better. I wish I could monitor my water temps somehow...

Thanks.
