HK cpu blocks....any huge performance difference between the LT and LC?

OK....as I see the Heatkiller cpu blocks, there are the LT/CU versions and the LC version.

What are the performance differences between the "cut down" LC vs. the LT/CU versions? Anyone have interior pics of the two? Well, having already seen inside the LT/CU, any pics of the LC interior?

Flow differences?

Ideas? Tests done on the two and links to said testing?

Thanks.

Just tired of looking at my Fuzion and wanting something different.....bored, I guess.

All I know is that the LC edition has fewer channels than the LT and CU.
