Your right, it feels like a lifetime I've been waiting for Joe's review. Every day I read all of his comments hoping for just a hint of what's coming.

Personally I've owned both a heater core (Exactly the same as the Big Momma or D-Tek), and a AC core (20 pass like the BE cooling).

I started with the AC core and it tromped my flow rate (as the tubes are only 3/8"), so later I modified it with copper pipe to make it like the BE unit with 2 flow paths. This really increased the observed flow, but only gained me a couple degrees on average.

Then I switched to a heater core from a '87 Chevette as a couple others where raving about them and my temps stayed the same, but the flow was MUCH faster. I figured this was due to the fact that I just placed the 120mm-4" fan directly on the 6"x6" surface and hot fluid could just bypass.

Constructing a crude paper shroud and moving the fan forwards again dropped about 3-4 degrees, but I'm not happy with the way it's mounted and am looking for a more solid metal (probably tin) option.

The truth is each rad has advanages and disadvantages (and will cool better) in different situations. The Black Ice already has a shroud / mount for a fan built in, so does the BE and Danger Den. So they are the easiest to set-up. The Black Ice is expensive and only will gain a couple degrees over a BE cooling with the same fan and mount position (which really is the sam as the Danger Den other than flow loss). Id' be more concerned with what will fit best, look best, be quitest and not be in the way daily. As for cooling, there all good choices and in my opinion with the right fan and shroud if necessary will be within a couple degrees of each other if all the components are designed to work with them.
