Well that's just it Bill, I've not seen a rad like my example on the right. I must confess, radiator's have not been something I take note to, I have been water cooling almost 5 years now and until recently, the bigger the thicker the better! FPI? WTF is that most would have said 6 months ago (well most like me anyway). When I was looking at the closup of the fins on the new PA series is when this fin idea hit me, but I thought there was absolutely a reason as to why it was NOT done this way.
